Every Avionaut Car Seat Explained, Compared & Independently Reviewed
From the ultra-light Pixel 3 to the Swedish Plus Tested Sky 2.0, discover which Avionaut car seat is right for your family with our complete buying guide.
Welcome
Choosing a car seat is one of the most important purchases you'll make as a parent. Long before your baby arrives, you'll probably find yourself comparing safety ratings, reading reviews, watching videos and trying to understand terms like i-Size, ISOFIX, ADAC and Swedish Plus Test. Before long, what should feel like an exciting decision can become overwhelming.
If you've discovered Avionaut, you've already stepped into the world of premium child safety. Unlike many manufacturers that produce everything from pushchairs to highchairs, Avionaut has built its reputation by focusing on one thing: creating exceptionally safe, ergonomic car seats designed to protect children from their very first journey home.
Today, Avionaut is trusted by child safety specialists, healthcare professionals and thousands of families across Europe. Its seats are recognised for their lightweight design, advanced ergonomics and commitment to independent safety testing. While the brand may not be as familiar to some UK parents as household names like Joie, Maxi-Cosi or Cybex, those who discover Avionaut often become lifelong advocates.
But with models such as the Pixel 3, Pixel PRO 2.0 C, Cosmo, Sky 2.0, Stardust 360, Stardust RWF and MaxSpace, choosing the right seat isn't always straightforward.
That's where this guide comes in.
Why We Created This Guide
Most Avionaut buying guides only scratch the surface. They list a few specifications, compare prices or repeat the manufacturer's brochure.
We wanted to create something different.
This guide has been written to help parents genuinely understand the Avionaut range—not just what each seat does, but why it was designed, who it's best suited to and how independent safety testing helps separate one model from another.

- The difference between ADAC testing, the Swedish Plus Test and R129 (i-Size).
- Why some seats receive better crash safety scores than others.
- Which models are designed for newborns, toddlers and older children.
- Whether a rotating seat or an extended rear-facing seat is the better choice for your family.
- Which Avionaut seat offers the best balance of safety, practicality and value.
By the time you've finished reading, you'll have the confidence to choose the right Avionaut car seat for your child and understand exactly why it's the right choice.
What You'll Find in This Guide
To make this guide easy to navigate, we've divided it into dedicated chapters covering every aspect of the Avionaut range.
You'll discover:

Before We Begin...
Every family is different.
The "best" car seat isn't always the most expensive one or the model with the longest feature list. It's the seat that fits your child, your vehicle and your everyday lifestyle, while being installed and used correctly every single time.
That's why, throughout this guide, we'll focus not only on independent safety performance but also on practicality, comfort, ease of use and long-term value—because all of these factors contribute to keeping your child safe on every journey.
Let's begin by exploring the story behind Avionaut and why this European manufacturer has become one of the most respected names in child car seat safety.

Meet the Avionaut Family
Which Avionaut Car Seat Is Right for Your Family?
One of the biggest mistakes parents make when shopping for a car seat is assuming there's one "best" model.
The truth is, there isn't.
The best car seat for a newborn living in a city apartment will often be very different from the best choice for a family travelling long distances every weekend.
That's exactly why Avionaut has developed a complete range of car seats designed for different stages of childhood, different vehicles and different lifestyles.
Some parents want the lightest infant carrier available.
Others prioritise keeping their child rear-facing for as long as possible.
Some want one car seat that lasts for years, while others simply want the easiest everyday experience with a rotating base.
Understanding what each model has been designed to do makes choosing the right seat much easier.
Let's meet the range.

| Model | Child Height | Best For | Rotation |
|---|---|---|---|
| Pixel 3 | 40–86cm | The latest premium infant carrier | IQ Orbit Compatible |

| Cosmo | Birth–87cm | Outstanding value and excellent ADAC performance | IQ Orbit Compatible |
| Sky 2.0 | Extended Rear Facing | Maximum rear-facing safety | No |
| Stardust 360 | 40–150cm | One seat from birth to approximately 12 years | ✅ |
| Stardust RWF | 40–105cm | Maximum rear-facing protection | 180 |
| MaxSpace | 100–150cm | Premium high-back booster | No |

Avionaut Pixel 3
The Next Generation of Newborn Safety
If there's one product that perfectly represents where Avionaut is heading as a brand, it's the Pixel 3.
Building on the success of the award-winning Pixel range, the Pixel 3 has been developed to make travelling with a newborn safer, lighter and more comfortable than ever before. Rather than simply updating the styling, Avionaut has refined almost every aspect of the seat—from the ergonomic insert and harness system to the fabrics and compatibility with its latest rotating ISOFIX base.
The result is an infant carrier that's designed not only to protect your baby in a collision, but to support them during every journey, whether that's the trip home from hospital, the weekly supermarket shop or your first family holiday.
For parents looking for a premium infant carrier that combines intelligent engineering with everyday practicality, the Pixel 3 sets a new benchmark.

| Suitable From | 40–86cm |
| Approximate Age | Birth to around 15 months |
| Maximum Child Weight | 13kg |
| Regulation | R129 (i-Size) |

Who Is the Pixel 3 Designed For?
The Pixel 3 is ideal for parents who want the latest generation of Avionaut infant carrier without compromise.
It's particularly suited to:
- First-time parents.
- Families using a travel system every day.
- Parents regularly moving the seat between vehicles.
- Families wanting compatibility with a rotating ISOFIX base.
- Those who value premium ergonomics alongside proven safety engineering.
Whether you're travelling five minutes to nursery or five hours to visit grandparents, the Pixel 3 has been designed to make every journey easier.
Why the Pixel 3 Matters
The first journey home from hospital is one of the most memorable moments in parenthood.
It's also one of the most important.
A newborn baby's body is still developing rapidly. Their muscles are weak, their spine is naturally curved and their head represents a much larger proportion of their body weight than it does later in childhood.
Supporting that tiny body correctly is just as important as protecting it during an impact.
That's why Avionaut has continued to work closely with specialists in child ergonomics when developing the Pixel 3.
Every element has been carefully considered to help maintain a natural, supported position during travel while remaining practical enough for everyday family life.
Designed Around Newborn Comfort
Unlike many infant carriers that simply scale down an adult seat shape, the Pixel 3 has been developed specifically around the needs of newborn babies.
The ergonomic insert helps support natural positioning while providing a secure and comfortable fit during those first precious months.
Combined with carefully shaped side protection and premium cushioning, the result is a seat that feels reassuringly supportive without feeling restrictive.
For parents, this means confidence that every journey begins with your baby sitting comfortably and securely.
Lightweight by Design
Anyone who has carried an infant carrier containing a growing baby knows one thing:
They get heavy—quickly.
Every unnecessary kilogram adds strain to your back, shoulders and arms.
That's why lightweight construction remains one of Avionaut's defining principles.
The Pixel 3 has been engineered to minimise weight wherever possible without compromising structural integrity.
Whether you're carrying your baby from the house to the car or clipping the seat onto a compatible pushchair chassis, you'll appreciate every gram that's been saved.
Did You Know?
Parents often spend more time carrying the infant carrier than driving with it. Lightweight construction isn't just about convenience—it can make everyday life significantly easier during the first year.
Travel System Ready
Modern family life rarely involves using a car seat in isolation.
The Pixel 3 integrates seamlessly with a wide range of compatible travel systems, allowing you to move your sleeping baby from car to pushchair without disturbing them.
For short journeys, school runs or quick shopping trips, this flexibility becomes invaluable.
Simply remove the seat from the vehicle, attach it to your pushchair chassis using the correct adapters and continue your journey.
No waking.
No transferring.
No unnecessary fuss.
IQ Orbit or Dock Base?
One of the Pixel 3's biggest advantages is its flexibility.
Parents can install the seat using:
- The vehicle's seat belt.
- The Avionaut Dock Base.
- The Avionaut IQ Orbit rotating base.
If convenience is your priority, the IQ Orbit transforms everyday use by rotating towards the vehicle door, making lifting your baby in and out significantly easier.
For families who prefer a simpler ISOFIX installation without rotation, the Dock Base offers excellent security and straightforward operation.
Whichever option you choose, the Pixel 3 has been designed to work seamlessly with both systems.
Independent Testing
At the time of writing, the Avionaut Pixel 3 is awaiting official ADAC testing, meaning no independent ADAC rating has yet been published.
Rather than speculate, Avionaut has chosen to wait for the official results.
This guide will be updated once independent testing has been completed.
While the Pixel 3 is new, it builds upon the engineering philosophy established by earlier Pixel models, including the Pixel PRO 2.0 C, which achieved an overall ADAC rating of 2.1 ("Good") when paired with the IQ Orbit base.
Is the Pixel 3 Right for You?
Choose the Pixel 3 if you want:
✅ Avionaut's newest infant carrier.
✅ Premium ergonomics from birth.
✅ Compatibility with the IQ Orbit rotating base.
✅ Lightweight everyday practicality.
✅ A premium travel system companion.

Overall Verdict
The Pixel 3 represents the next chapter in Avionaut's infant carrier range. Rather than reinventing what already worked, it refines it—combining premium materials, ergonomic design and everyday practicality into a seat that's built for modern family life.
For parents wanting Avionaut's latest technology from day one, the Pixel 3 is an outstanding place to begin.
Coming Up Next
The Pixel 3 may be Avionaut's newest infant carrier, but it's not the lightest.
In the next chapter, we'll take a closer look at the Pixel PRO 2.0 C—the remarkably lightweight infant carrier that has become one of Avionaut's most recognised products and achieved an impressive ADAC "Good" (2.1) rating when used with the IQ Orbit base.

Avionaut Pixel PRO 2.0 C
The Ultra-Light Infant Carrier That Changed Expectations
When Avionaut introduced the Pixel range, it challenged one of the biggest assumptions parents had about infant car seats.
Heavier doesn't necessarily mean safer.
For years, parents accepted that carrying a bulky infant carrier was simply part of life with a newborn. Lifting a seat in and out of the car, carrying it across a supermarket car park or clipping it onto a pushchair chassis often became one of the most physically demanding parts of the day.
Avionaut saw an opportunity to do something different.
Rather than accepting unnecessary weight as inevitable, its engineers asked a simple question:
Could an infant carrier be significantly lighter without compromising safety?
The answer became the Pixel PRO 2.0 C.
Today, it remains one of the lightest premium infant carriers available, proving that advanced engineering, carefully selected materials and intelligent design can reduce weight while still delivering outstanding protection.
At a Glance
| Feature | Details |
|---|---|
| Suitable From | 40–86cm |
| Approximate Age | Birth to around 15 months |
| Maximum Child Weight | 13kg |
| Weight | Approx. 2.5kg |
| Regulation | R129 (i-Size) |
| Installation | Vehicle seat belt, Dock Base or IQ Orbit Base |
| Rotation | Compatible with IQ Orbit 360° Base |
| ADAC Rating | 2.1 (Good) with IQ Orbit Base |
Why Is Everyone Talking About the Pixel PRO?
Ask almost anyone who has owned one and you'll hear the same answer.
It's unbelievably light.
That might sound like a small advantage.
It isn't.
Think about how many times you'll lift an infant carrier during the first year.
- Into the car.
- Out of the car.
- Onto a pushchair.
- Into the house.
- To the nursery.
- Through the supermarket.
- At the doctor's surgery.
- At grandparents' house.
Those lifts quickly add up.
When your baby weighs 8 or 9 kilograms, every kilogram you save on the car seat itself becomes genuinely noticeable.
For many parents, it's the difference between carrying the seat comfortably with one hand or constantly swapping arms halfway across the car park.
Engineered for Everyday Life
Reducing weight wasn't simply about making the Pixel PRO easier to carry.
It also improves everyday usability.
The lighter the seat, the easier it becomes to:
- Move between vehicles.
- Attach to a travel system.
- Lift safely without straining your back.
- Carry upstairs.
- Manage while holding shopping bags or changing bags.
It's one of those features you don't fully appreciate until you've lived with it.
Expert Tip
If you're recovering from a Caesarean section or regularly lifting your baby between the house, car and pushchair, the weight of an infant carrier can make a significant difference to everyday comfort.
Safety Comes First
Of course, weight means very little without protection.
Fortunately, the Pixel PRO 2.0 C delivers both.
When paired with the IQ Orbit Base, it achieved an overall ADAC rating of 2.1 ("Good"), demonstrating excellent all-round performance in one of Europe's most respected independent child car seat tests.
ADAC doesn't just assess crash protection.
It also evaluates:
- Ease of installation.
- Ergonomics.
- Risk of misuse.
- Comfort.
- Harmful substances.
Achieving a strong ADAC result therefore reflects the seat's performance across a wide range of real-world conditions, not simply laboratory crash testing.
Ergonomics Designed Around Newborns
One of Avionaut's greatest strengths is its understanding that newborn comfort and safety go hand in hand.
The Pixel PRO features an ergonomic insert designed to help support a baby's natural posture during those first months of life.
Rather than simply filling empty space, the insert has been carefully developed to:
- Encourage healthy spinal positioning.
- Provide even body support.
- Help maintain comfortable head alignment.
- Offer a secure fit for smaller babies.
This thoughtful approach reflects Avionaut's wider philosophy of designing seats around child development rather than simply meeting minimum safety requirements.
IQ Orbit Compatibility
The Pixel PRO 2.0 C is fully compatible with the Avionaut IQ Orbit rotating ISOFIX base.
The 360° rotation makes everyday life noticeably easier.
Instead of leaning awkwardly into the vehicle, parents can simply rotate the seat towards the door before lifting their baby in or out.
It's one of those features that quickly becomes indispensable—especially during the early months when lifting and fastening a newborn can feel awkward.
If you don't require rotation, the Pixel PRO can also be installed using the Dock Base or the vehicle's seat belt.
Travel System Ready
Like the Pixel 3, the Pixel PRO integrates seamlessly with many leading pushchair brands using the appropriate adapters.
This allows parents to transfer a sleeping baby from the car to the pushchair without disturbing them—particularly useful for shorter journeys, appointments or quick shopping trips.
Pixel PRO 2.0 C vs Pixel 3
This is one of the most common questions parents ask.
Both are premium infant carriers.
Both are compatible with the IQ Orbit Base.
Both meet the latest R129 safety standards.
So what's the difference?
Choose the Pixel PRO 2.0 C if you:
- Want one of the lightest infant carriers available.
- Prefer a model with a published ADAC result.
- Value proven independent testing.
Choose the Pixel 3 if you:
- Want Avionaut's newest infant carrier.
- Prefer the latest design refinements and updated ergonomics.
- Don't mind waiting for official ADAC results to be published.
Neither is the wrong choice.
It simply depends on whether you prioritise proven independent testing today or Avionaut's newest generation of design.
Is the Pixel PRO Right for You?
The Pixel PRO 2.0 C is ideal for:
✔ Parents carrying the seat regularly.
✔ Families using a travel system every day.
✔ Anyone recovering from childbirth who wants to minimise lifting.
✔ Parents who value independently tested safety.
✔ Families wanting premium engineering without unnecessary weight.

Our Verdict
The Pixel PRO 2.0 C remains one of the most impressive infant carriers on the market—not because it's packed with gimmicks, but because it solves real problems for real parents.
Its remarkably low weight makes everyday life easier, while its excellent ADAC performance demonstrates that lightweight engineering doesn't have to come at the expense of safety.
Although the newer Pixel 3 now sits alongside it in the Avionaut range, the Pixel PRO 2.0 C continues to be an outstanding choice for parents who value independently tested performance and exceptional everyday practicality.
Coming Up Next
Not every family needs the lightest infant carrier on the market.
In the next chapter, we'll explore the Avionaut Cosmo—a seat that proves exceptional safety doesn't have to come with the highest price tag. With outstanding ADAC crash performance and an impressive five-star safety rating, the Cosmo has become one of the best-value premium infant carriers available.

Avionaut Cosmo
Outstanding Safety Without the Premium Price Tag
When shopping for an infant car seat, it's easy to assume that spending more automatically means getting a safer product.
The Avionaut Cosmo proves that isn't always the case.
Positioned as the most accessible infant carrier in the Avionaut range, the Cosmo has become one of the brand's biggest success stories. Rather than stripping away important features to reduce the price, Avionaut focused on retaining what matters most—excellent crash protection, low weight, ergonomic comfort and straightforward everyday usability.
The result is an infant carrier that offers exceptional value while achieving one of the strongest independent safety performances in its class.
For many families, the Cosmo represents the perfect balance between affordability and premium engineering.

Who Is the Cosmo Designed For?
The Cosmo is ideal for parents who want the reassurance of Avionaut engineering without stepping into the very top end of the range.
It's particularly well suited to:
- First-time parents.
- Families shopping to a budget.
- Grandparents needing an additional infant carrier.
- Parents who want excellent independent safety credentials.
- Families looking for a lightweight, easy-to-use seat.
If your priority is maximum safety and outstanding value, the Cosmo deserves serious consideration.
Small in Price. Big on Safety.
One of the reasons the Cosmo has become so popular is simple.
It performs exceptionally well where it matters most.
In independent ADAC testing, the Cosmo achieved outstanding results, particularly in crash protection.
ADAC Highlights
| Test Category | Result |
|---|---|
| Overall Safety | ⭐⭐⭐⭐⭐ |
| Frontal Impact Protection | 1.0 |
| Side Impact Protection | 1.2 |
| Ergonomics | 2.3 |
| Ease of Use | 2.0 |
These results place the Cosmo among the strongest-performing infant carriers in its category.
What makes this even more impressive is that these scores aren't marketing claims—they come from one of Europe's most respected independent testing organisations.
Did You Know?
In ADAC testing, lower numbers are better. A frontal impact score of 1.0 and side impact score of 1.2 represent outstanding crash performance.
Designed Around Everyday Parenting
Life with a newborn is busy enough without fighting with complicated equipment.
The Cosmo has been designed to make everyday journeys simple.
Its lightweight construction makes it easy to carry between the house and the car, while intuitive installation helps parents feel confident every time they travel.
Whether you're dropping older children at school, heading to a medical appointment or visiting friends, the Cosmo has been built to fit naturally into family life.
Comfort From Day One
A newborn's first few months involve rapid growth and development.
That's why Avionaut has designed the Cosmo to provide more than just protection in the event of a collision.
The carefully shaped interior helps support your baby's natural position while offering the comfort needed for everyday travel.
Soft fabrics, supportive padding and a secure harness combine to create a reassuring environment for even the smallest passengers.
Whether your journey lasts five minutes or several hours, your baby remains supported throughout.
Travel System Ready
Like the rest of Avionaut's infant carrier range, the Cosmo integrates with many leading pushchair brands using the correct adapters.
This allows parents to move a sleeping baby from the car to the pushchair without interruption—a feature that quickly becomes invaluable during everyday life.
For busy families, that flexibility can be just as important as the crash protection itself.
Cosmo vs Pixel PRO 2.0 C
One question we hear regularly is:
"Should I buy the Cosmo or spend more on the Pixel PRO?"
The answer depends on your priorities.
Choose the Cosmo if you:
- Want exceptional safety at a lower price.

🏆 Best Value Infant Carrier
If you're looking for the strongest combination of price, protection and everyday usability, the Avionaut Cosmo stands out as one of the best-value premium infant carriers available today.
Our Verdict
The Cosmo perfectly demonstrates Avionaut's philosophy that outstanding child safety shouldn't be reserved only for flagship products.
With exceptional ADAC crash performance, lightweight construction and thoughtful everyday practicality, it offers parents genuine peace of mind without demanding the highest price.
If your goal is to maximise value without compromising on what matters most, the Avionaut Cosmo is one of the easiest recommendations in the entire Avionaut range.
Coming Up Next
Until now we've focused on infant carriers designed for your baby's earliest journeys.
In the next chapter, we'll move into one of the most important decisions parents make after the first year—whether to choose a rotating seat or keep their child rear-facing for as long as possible. We'll begin with one of Avionaut's most respected models: the Sky 2.0, a Swedish Plus Tested seat developed for families who want to prioritise extended rear-facing travel and maximum protection.

Avionaut Sky 2.0
Maximum Rear-Facing Safety. Maximum Peace of Mind.
For many parents, choosing an infant carrier is relatively straightforward.
The bigger question comes later.
What happens when my baby outgrows it?
This is the point where families often face one of the most important decisions they'll make.
Do you move to a rotating seat that can eventually face forwards?
Or do you keep your child rear-facing for as long as possible?
If maximum protection is your priority, the Avionaut Sky 2.0 has become one of Europe's most respected extended rear-facing car seats.
Designed to keep children travelling rear-facing for significantly longer than many conventional seats, the Sky 2.0 has earned the prestigious Swedish Plus Test certification—an achievement regarded by many child safety specialists as one of the highest standards in child passenger protection.
It isn't the easiest seat to install.
It isn't the smallest.
It doesn't rotate.
And that's exactly the point.
The Sky wasn't designed around convenience.
It was designed around one objective:
Keeping children as safe as possible during a frontal collision.
At a Glance
| Feature | Details |
|---|---|
| Suitable From | 40–125cm* |
| Approximate Age | Birth to around to 6 years** |
| Installation | Vehicle seat belt with lower tethers |
| Rotation | No |
| Regulation | R129 (i-Size) |
| Swedish Plus Tested | ✅ Yes |
| ADAC Overall | 3.4 (Satisfactory) |
Always follow the manufacturer's height requirements and ensure your child meets the minimum criteria before moving from an infant carrier.
Who Is the Sky 2.0 Designed For?
The Sky isn't for every family.
It's for parents who have already decided one thing.
They want their child to remain rear-facing for as long as possible.
It's ideal for:
- Parents who prioritise safety over convenience.
- Families following extended rear-facing recommendations.
- Long-distance travellers.
- Parents wanting Swedish Plus Tested protection.
- Families who understand the benefits of rear-facing beyond infancy.
If you're prepared to spend a little longer installing your seat in exchange for exceptional protection, the Sky 2.0 is one of the strongest choices available.
Why Rear-Facing Matters
One of the biggest myths surrounding child car seats is that children should move into a forward-facing seat as soon as possible.
Modern safety research tells a very different story.
During a frontal collision, a forward-facing child's head continues travelling forwards while the harness restrains the body.
This places enormous forces on the neck.
Young children's bones and muscles are still developing, making them far more vulnerable than adults.
A rear-facing seat works differently.
Instead of the harness absorbing those forces alone, the shell of the seat supports the entire head, neck and back.
The energy is spread across a much larger area of the body.
The result is dramatically lower forces acting on the neck.
That's why child safety experts across Europe continue to recommend keeping children rear-facing for as long as practical.
Did You Know?
Many Scandinavian countries have kept children rear-facing until around four years of age for decades—and they consistently report some of the lowest rates of serious child injury in road traffic collisions.
It's no coincidence that the Swedish Plus Test also originated in Sweden.
Swedish Plus Tested
The words "Swedish Plus Tested" appear on relatively few child car seats.
That's because achieving this certification is incredibly difficult.
Unlike standard approval testing, the Swedish Plus Test focuses on one specific measurement:
The force transmitted to a child's neck during a severe frontal collision.
If those forces exceed the strict limit...
The seat fails.
There are no grades.
No silver medals.
No "almost passed."
It either meets the required standard...
Or it doesn't.
The Sky 2.0 does.
For many parents, that certification alone is one of the biggest reasons for choosing it.
Understanding the ADAC Score
Some parents notice that the Sky's overall ADAC score is 3.4 and immediately wonder why.
The answer highlights why understanding ADAC is so important.
Crash Protection
Frontal Impact
1.4
Side Impact
1.2
These are excellent crash performance scores.
So why isn't the overall score higher?
Because ADAC also assesses:
- Installation complexity.
- Risk of misuse.
- Ergonomics.
- Space inside the vehicle.
- Everyday usability.
The Sky requires a more involved installation than many rotating ISOFIX seats.
It also occupies more space within the vehicle.
These practical considerations influenced the overall score—not poor crash protection.
Expert Insight
If your primary concern is crash safety, it's important to look beyond the headline ADAC rating. The Sky 2.0 achieved excellent frontal and side-impact scores, with the overall result reflecting practicality and installation rather than a weakness in protection.
Designed for Growing Children
One concern many parents have about extended rear-facing seats is comfort.
Will older children really be happy travelling backwards?
The answer may surprise you.
Children are far more flexible than adults.
Many naturally sit cross-legged, rest their feet against the vehicle seat or simply change position throughout longer journeys.
The Sky 2.0 has been designed with generous internal space, supportive padding and carefully shaped side wings to provide comfort throughout the years your child uses it.
Parents often worry far more about legroom than children ever do.
Is the Sky Difficult to Use?
Let's be honest.
Compared with a modern rotating ISOFIX seat...
Yes.
It takes more time to install.
It requires careful adjustment.
It isn't designed to be moved regularly between vehicles.
But once installed correctly, most families leave it in place for years.
For parents prioritising maximum rear-facing protection, that extra installation time is often seen as a worthwhile trade-off.
Sky 2.0 vs Stardust RWF
This is another question we hear regularly.
Both are Swedish Plus Tested.
Both prioritise rear-facing travel.
Both offer exceptional protection.
The difference comes down to how you plan to use them.
Choose the Sky 2.0 if you:
- Want a dedicated extended rear-facing seat.
- Prioritise proven crash performance.
- Don't need long-term forward-facing use.
Choose the Stardust RWF if you:
- Want a newer design with an extended height range.
- Prefer the latest Avionaut engineering.
- Want maximum rear-facing longevity before transitioning to a booster.
We'll explore the Stardust RWF in the next chapter.
Is the Sky 2.0 Right for You?
Choose the Sky if your priorities are:
✅ Swedish Plus Tested protection.
✅ Extended rear-facing travel.
✅ Outstanding frontal impact performance.
✅ Specialist engineering.
✅ Long-term peace of mind.

🏆 Best Extended Rear-Facing Car Seat
For families who believe rear-facing for as long as possible is the safest choice, the Sky 2.0 remains one of the most respected options available anywhere in Europe.
Our Verdict
The Sky 2.0 isn't trying to be the easiest seat to install or the most feature-packed on the market.
Instead, it focuses relentlessly on one objective: providing outstanding protection through extended rear-facing travel.
Its Swedish Plus Test certification, excellent crash performance and specialist design have made it a favourite among child safety professionals and parents who place maximum protection above everything else.
If your goal is to keep your child rear-facing for as long as possible, the Avionaut Sky 2.0 deserves a place at the very top of your shortlist.

Avionaut Stardust 360
One Car Seat. Twelve Years of Adventures.
For many parents, buying a car seat isn't simply about today's journey.
It's about avoiding having to buy another one next year.
That's exactly the thinking behind the Avionaut Stardust 360.
Designed to accompany your child from 40cm all the way to 150cm, the Stardust 360 is Avionaut's most versatile car seat. Rather than replacing multiple seats as your child grows, the Stardust adapts through every major stage of childhood—from your baby's very first journey home to the day they no longer require a child seat.
But longevity is only part of the story.
The Stardust 360 has been designed to make everyday parenting easier.
Its smooth 360° rotation simplifies getting your child in and out of the car, while intelligent ergonomics, premium materials and carefully considered engineering ensure every journey is as comfortable as it is safe.
It's a seat built not just to grow with your child—but to grow with your family.

|---|---|
| Suitable From | 40–150cm |
| Approximate Age | Birth to around 12 Years |

Who Is the Stardust 360 Designed For?
The Stardust 360 is ideal for families who want one premium car seat capable of supporting their child through multiple stages of growth.
It's particularly suited to:
- First-time parents.
- Families wanting to minimise future purchases.
- Parents who regularly lift children in and out of the car.
- Grandparents looking for a long-term solution.
- Anyone who values convenience alongside safety.
If you're looking for a seat that combines longevity with everyday practicality, the Stardust 360 is one of the strongest options in the Avionaut range.
One Seat From Birth to 150cm
Buying multiple car seats over the years can become expensive.
Infant carrier.
Toddler seat.
High-back booster.
Each transition means another decision.
Another installation.
Another purchase.
The Stardust 360 simplifies that journey.
Designed for children from 40cm to 150cm, it adapts as your child grows, reducing the need to replace seats throughout childhood.
For many families, this isn't just convenient—it offers genuine long-term value.
360° Rotation Changes Everyday Life
If you've never used a rotating car seat before, it's difficult to appreciate just how much difference it makes.
Instead of leaning awkwardly into the vehicle while trying to tighten the harness...
Simply rotate the seat towards the door.
Lift your child in.
Fasten the harness comfortably.
Rotate the seat back into the travelling position.
Simple.
Parents often tell us that once they've experienced a rotating seat, they wouldn't want to go back.
It's particularly helpful:
- After a Caesarean section.
- For grandparents.
- With larger toddlers.
- In smaller cars where space is limited.
- During everyday nursery and school runs.
Sometimes the biggest improvements are the simplest ones.
Expert Tip
A rotating seat doesn't just make life easier—it can also encourage correct everyday use. When harnessing your child is simpler and more comfortable, parents are more likely to take the time to achieve the correct fit on every journey.
Understanding the ADAC Result
The Stardust 360 achieved an overall ADAC rating of 3.3 (Satisfactory).
At first glance, some parents wonder whether this means it's less safe than other Avionaut seats.
The answer is no.
Once again, it's important to understand what ADAC actually measures.
Security
ADAC praised:
- Good belt routing.
- Excellent vehicle stability.
The report concluded there was an average risk of injury in both frontal and side impacts, contributing to the overall security score of 3.0.
Operation
ADAC highlighted:
✔ Very good build quality.
✔ Machine washable cover.
It also noted that:
- The instructions could be clearer.
- There is potential for incorrect installation if instructions aren't followed carefully.
- Harnessing the child takes slightly longer than some competitors.
- The seat itself is relatively heavy.
These practical factors influenced the overall score.
Ergonomics
The Stardust received positive feedback for:
- Comfortable seat padding.
Areas identified for improvement included:
- Leg support.
- Seating position.
- The amount of space required within smaller vehicles.
- The child's outward visibility.
Importantly, these observations relate to convenience and comfort—not structural safety.
Why Isn't the Stardust Swedish Plus Tested?
This is probably the most common question we receive about the Stardust.
The answer surprises many parents.
The Stardust isn't Swedish Plus Tested because it can't be.
Not because it failed.
Because it isn't eligible.
The Swedish Plus Test is only available to rear-facing-only car seats.
The Stardust 360 is designed to grow with your child and eventually allows forward-facing travel.
That automatically excludes it from Swedish Plus certification.
It doesn't mean the Stardust is unsafe.
It simply means it serves a different purpose.
Think of it this way:
The Sky 2.0 and Stardust RWF have one objective:
Maximum rear-facing protection.
The Stardust 360 has a different objective:
Providing safe, practical transport from birth through to approximately twelve years while making everyday family life easier.
Those are two very different design philosophies.
Premium Materials Matter
Safety is only one part of a child's journey.
Comfort matters too.
The Stardust features thoughtfully selected materials designed to support children through years of everyday use.
ADAC testing also concluded that the seat contains very low levels of pollutants, including PFAS (per- and polyfluoroalkyl substances), giving parents additional reassurance about the materials used throughout the product.
It's another example of Avionaut considering the whole ownership experience—not just crash testing.
Stardust 360 vs Sky 2.0
Parents often compare these two seats.
Here's the simplest way to think about it.
Choose the Sky 2.0 if:
- Your priority is maximum rear-facing protection.
- You want Swedish Plus Tested certification.
- You don't mind a more involved installation.
- You intend to keep your child rear-facing for as long as possible.
Choose the Stardust 360 if:
- You want one seat from birth to around 12 years.
- You value the convenience of 360° rotation.
- You want to simplify everyday loading.
- You prefer a seat that adapts as your child grows.
Neither seat is objectively "better."
They're simply designed for different families.
Is the Stardust 360 Right for You?
Choose the Stardust if you want:
✅ One seat from birth to 150cm.
✅ Smooth 360° rotation.
✅ Long-term value.
✅ Premium European engineering.
✅ Everyday convenience without sacrificing safety.

🏆 Best All-in-One Car Seat
If you're looking for a single premium seat that will support your child from birth through to approximately 12 years while making everyday life easier, the Stardust 360 is our top recommendation.
Our Verdict
The Avionaut Stardust 360 isn't trying to compete with dedicated rear-facing seats like the Sky 2.0 or Stardust RWF.
Instead, it offers something different.
It combines premium safety, intelligent engineering and exceptional day-to-day convenience in a seat that grows with your child for over a decade.
For busy families who value simplicity, versatility and long-term value, it's one of the most compelling all-stage car seats available today.
Coming Up Next
Some parents aren't looking for convenience.
They're looking for the highest possible level of rear-facing protection.
In the next chapter, we'll explore the Avionaut Stardust RWF—a Swedish Plus Tested seat that takes everything Avionaut has learned about child safety and applies it to one goal: keeping children rear-facing for as long as possible.

Avionaut Stardust RWF
Maximum Rear-Facing Safety. Everyday Convenience.
For years, parents wanting the highest level of rear-facing protection often had to accept one compromise.
Convenience.
Traditional extended rear-facing seats offered exceptional protection but could sometimes make everyday life more challenging. Lifting a child into the car, fastening the harness and reaching into the vehicle became increasingly difficult as children grew.
The Avionaut Stardust RWF changes that.
Designed for children from 40cm to 105cm, the Stardust RWF combines one of the most respected safety certifications in the world—the Swedish Plus Test—with an intelligent 180° Easy-Access Rotation that makes getting your child in and out of the car significantly easier.
It isn't designed to become a forward-facing seat.
It isn't designed to last until secondary school.
Instead, it has one clear mission:
To provide the highest possible level of rear-facing protection throughout the years when it matters most.
At a Glance
| Feature | Details |
|---|---|
| Suitable From | 40–105cm |
| Approximate Age | Birth to around 4 years* |
| Installation | ISOFIX |
| Loading Rotation | 180° Easy-Access Rotation |
| Travel Direction | Rear-Facing Only |
| Regulation | R129 (i-Size) |
| Swedish Plus Tested | ✅ Yes |
Always follow your child's height rather than age when deciding when to move between car seats.
Who Is the Stardust RWF Designed For?
The Stardust RWF has been developed for parents who believe rear-facing travel offers the safest possible way for young children to travel.
It's an excellent choice for:
- Parents wanting Swedish Plus Tested protection.
- Families planning to rear-face for as long as possible.
- Parents who value convenience without compromising on safety.
- Families looking for premium engineering and long-term comfort.
- Those wanting an ISOFIX rear-facing seat that's easy to live with every day.
If your priority is maximum protection, this is one of the strongest seats Avionaut has ever produced.
Why Rear-Facing Matters
One of the most important advances in child passenger safety has been the growing understanding of just how beneficial rear-facing travel is for young children.
A baby's body is very different from an adult's.
Their head is proportionally much larger.
Their neck muscles are still developing.
Their spine remains flexible throughout the early years.
During a frontal collision, these differences become incredibly important.
A forward-facing child is restrained by the harness while their head continues moving forwards, placing enormous forces on the neck.
A rear-facing seat works in a completely different way.
Instead of allowing those forces to concentrate on the neck, the shell of the car seat supports the child's head, neck, shoulders and back, spreading crash energy across the strongest parts of the body.
That's why many child safety experts recommend keeping children rear-facing for as long as possible.
The Stardust RWF has been engineered to make that decision easier.
Swedish Plus Tested
Very few words carry more significance in the child safety world than Swedish Plus Tested.
Unlike standard approval tests, the Swedish Plus Test focuses on one critical measurement:
The forces acting on a child's neck during a severe frontal collision.
The limits are extremely demanding.
If a seat exceeds them...
It fails.
There are no grades.
No silver medals.
No "almost."
The seat either passes...
Or it doesn't.
The Avionaut Stardust RWF proudly carries this certification, placing it among a select group of rear-facing car seats that have demonstrated exceptionally low neck loads during testing.
For many parents, that's one of the strongest reassurances any car seat can offer.
Did You Know?
The Swedish Plus Test is voluntary. Manufacturers choose to submit their products for testing because they believe they can meet one of the toughest child safety standards in the world.
Rear-Facing Safety Without the Struggle
One of the biggest concerns parents have about dedicated rear-facing seats isn't safety.
It's practicality.
Getting a toddler into a rear-facing seat can sometimes feel awkward, particularly in smaller vehicles.
That's where the Stardust RWF stands apart.
Its clever 180° Easy-Access Rotation allows the seat to turn towards the vehicle door while you're placing your child into the seat or fastening the harness.
Once your child is safely secured, the seat rotates back into its locked rear-facing travel position.
The result?
The convenience of a rotating seat...
Without compromising the rear-facing philosophy that makes the Stardust RWF so special.
Why Doesn't It Rotate 360°?
This is one of the questions we're asked most often.
The answer is surprisingly simple.
The Stardust RWF isn't designed to become a forward-facing seat.
Its rotation exists purely to make everyday loading easier.
By remaining a dedicated rear-facing model throughout its usable lifespan, Avionaut has been able to optimise the seat around one goal:
Delivering the highest possible level of rear-facing protection.
That commitment is one of the reasons it successfully achieved Swedish Plus Test certification.
Built Around Growing Children
The Stardust RWF has been designed to support children from 40cm to 105cm, making it suitable from birth through the most important early years of development.
Throughout that time, the seat grows alongside your child.
Features include:
- Adjustable headrest.
- Premium newborn insert.
- Deep protective side wings.
- Breathable upholstery.
- Supportive seating position.
- High-quality materials throughout.
As children grow, the seat adapts with them, maintaining excellent support and comfort at every stage.
Comfort on Every Journey
Parents often worry that older children won't enjoy sitting rear-facing.
Interestingly...
Children rarely share that concern.
Unlike adults, young children naturally sit with crossed legs, bent knees or their feet resting comfortably against the vehicle seat.
Most simply adapt without thinking about it.
The Stardust RWF has been designed with generous internal space and supportive cushioning to keep children comfortable on both short journeys and longer family adventures.
Stardust RWF vs Stardust 360
Although they share a family name, these two seats have been designed for different priorities.
Choose the Stardust RWF if you:
- Want Swedish Plus Tested protection.
- Plan to keep your child rear-facing throughout the seat's lifespan.
- Like the convenience of 180° Easy-Access Rotation.
- Want a dedicated rear-facing solution from birth to 105cm.
Choose the Stardust 360 if you:
- Want one seat from 40–150cm.
- Need full 360° rotation.
- Plan to transition to forward-facing travel later.
- Prefer maximum long-term flexibility.
Neither seat is better.
They simply reflect two different parenting philosophies.
One prioritises lifelong versatility.
The other prioritises maximum rear-facing protection.

🏆 Best Premium Rear-Facing Car Seat
The Stardust RWF combines the reassurance of Swedish Plus Test certification with one of the most practical innovations we've seen in a dedicated rear-facing seat. Its 180° Easy-Access Rotation removes one of the biggest frustrations parents associate with rear-facing travel, making it easier to enjoy the benefits of extended rear-facing without compromising everyday usability.
Our Verdict
The Avionaut Stardust RWF demonstrates that parents no longer have to choose between maximum safety and everyday convenience.
By combining Swedish Plus Tested protection with intelligent 180° Easy-Access Rotation, Avionaut has created a seat that makes rear-facing travel more practical without losing sight of its primary purpose.
If your goal is to keep your child rear-facing throughout their earliest years while making daily life easier for yourself, the Stardust RWF is one of the most compelling rear-facing car seats available today.
Coming Up Next
We've explored Avionaut's infant carriers, extended rear-facing seats and all-stage solutions.
Next, we'll look at the Avionaut MaxSpace—a premium high-back booster designed to prove that older children deserve the same level of comfort, engineering and independent safety as babies and toddlers.

Avionaut MaxSpace
Because Growing Children Still Deserve Outstanding Protection
By the time a child is ready for a high-back booster seat, many parents feel they've reached the final chapter of their car seat journey.
The sleepless nights are becoming memories.
The infant carrier has long since been packed away.
Your toddler has grown into a confident, chatty child who climbs into the car by themselves.
It's easy to assume that the difficult decisions are over.
In reality, choosing the right booster seat is just as important as choosing your very first infant carrier.
Although older children are physically stronger, they still need carefully engineered protection to ensure the vehicle's seat belt fits correctly, manages crash forces effectively and provides comfort during everyday travel.
That's exactly why Avionaut created the MaxSpace.
Designed for children from 100cm to 150cm, the MaxSpace combines intelligent engineering, premium comfort and independently tested safety to support children throughout the final stage of their car seat journey.
At a Glance
| Feature | Details |
|---|---|
| Suitable From | 100–150cm |
| Approximate Age | Around 3½–12 years* |
| Installation | ISOFIX with vehicle seat belt |
| Travel Direction | Forward Facing |
| Regulation | R129 (i-Size) |
| ADAC Rating | 2.3 – Good |
Always use your child's height rather than age to determine when they are ready to transition to a high-back booster.
Who Is the MaxSpace Designed For?
The MaxSpace has been developed for growing children who have outgrown their rear-facing or harnessed car seat but still require the protection and positioning provided by a high-back booster.
It's an excellent choice for:
- Families moving on from an extended rear-facing seat.
- Parents who travel long distances.
- Older children who need additional comfort.
- Families wanting premium safety without compromising on everyday usability.
- Parents who value independently tested performance.
Rather than simply raising your child higher in the vehicle, the MaxSpace has been engineered to ensure the seat belt fits exactly where it should.
Why Booster Seats Matter More Than You Think
Many people assume a booster seat is simply there to help a child see out of the window.
In reality, its job is far more important.
Vehicle seat belts are designed around the proportions of an average adult.
Without a correctly designed booster seat, the belt may sit too high across a child's abdomen or too close to their neck.
During a collision, that poor positioning can significantly increase the risk of injury.
A high-quality booster seat helps to:
- Position the lap belt correctly across the pelvis.
- Guide the shoulder belt comfortably across the shoulder.
- Support the head and upper body.
- Improve side-impact protection.
- Encourage children to sit in the safest possible position throughout every journey.
The MaxSpace has been designed around these principles, helping the vehicle's own safety systems work as effectively as possible.
Independently Tested Safety
The MaxSpace has achieved an impressive ADAC rating of 2.3 ("Good"), reflecting strong all-round performance in one of Europe's most respected independent child car seat tests.
As we've discussed earlier in this guide, ADAC doesn't only evaluate crash protection.
It also considers:
- Ease of installation.
- Ergonomics.
- Child comfort.
- Ease of use.
- Harmful substances.
This means the MaxSpace has demonstrated its capabilities not only in laboratory testing but also in the practical areas that matter to families every day.
Designed for Longer Journeys
As children grow older, they often spend more time in the car.
School runs become sports clubs.
Weekend visits become family holidays.
Comfort becomes increasingly important.
The MaxSpace has been designed with this in mind.
Its generous seating area, supportive side wings and carefully shaped headrest provide excellent comfort, even on longer journeys.
Rather than encouraging children to slump or lean awkwardly against the vehicle door, the seat promotes a natural, supported seating position that remains comfortable mile after mile.
Expert Tip
A comfortable child is more likely to remain seated correctly throughout a journey. Good posture isn't just about comfort—it's an important part of ensuring the vehicle's seat belt continues to protect them as intended.
Built to Grow
Children don't stop growing once they reach booster-seat age.
The MaxSpace has been designed to adapt with them.
Its adjustable headrest and spacious internal dimensions allow the seat to continue providing excellent support throughout years of growth, helping parents avoid replacing booster seats unnecessarily.
For many families, it's the final car seat they'll ever need to buy.
Premium Comfort, Everyday Practicality
Avionaut believes that older children deserve the same level of comfort and quality as babies.
That's reflected throughout the MaxSpace.
Premium upholstery, supportive cushioning and thoughtful ergonomics combine to create a seat that children genuinely enjoy travelling in.
Parents will also appreciate the straightforward installation and intuitive adjustment, making it easy to achieve the correct fit as children grow.
MaxSpace vs a Standard Booster Cushion
This is one of the most common questions we hear.
The answer is simple.
A backless booster cushion may raise a child into a better position, but it doesn't provide the same level of:
- Side-impact protection.
- Head support.
- Belt guidance.
- Upper-body positioning.
- Comfort during longer journeys.
A high-back booster like the MaxSpace has been engineered to work with your vehicle's seat belt, helping it perform as effectively as possible while also protecting your child in side-impact collisions.
Is the MaxSpace Right for You?
The MaxSpace is ideal if you:
✅ Need a premium high-back booster from 100–150cm.
✅ Want independently tested safety.
✅ Value comfort on longer journeys.
✅ Want a seat that grows with your child.
✅ Prefer premium European engineering.
Independent Safety

Editor's Choice
🏆 Best Premium High-Back Booster
The MaxSpace proves that excellent child protection doesn't stop once your child leaves a harnessed seat. Combining premium comfort, thoughtful ergonomics and strong independent safety credentials, it's an outstanding choice for the final stage of your child's car seat journey.
Our Verdict
The Avionaut MaxSpace brings the same philosophy found throughout the rest of the Avionaut range to older children.
Rather than treating booster seats as an afterthought, Avionaut has created a product that prioritises proper belt positioning, long-distance comfort and independently verified safety.
For families looking for a premium high-back booster that will support their child from 100cm to 150cm, the MaxSpace is a fitting conclusion to the Avionaut journey.
Coming Up Next
We've now explored every car seat in the Avionaut range.
Next, we'll look at the two ISOFIX bases that support the infant carriers—the IQ Orbit and the Dock Base. We'll explain the differences between them, who they're designed for, and whether a rotating base is worth the extra investment. This chapter will help parents complete their travel system with confidence.
IQ Orbit vs Dock Base
Choosing the Right Avionaut Base
Selecting the right infant carrier is only part of the journey.
The base you choose will influence every journey you make during your baby's first year—from the school run and supermarket trips to long family adventures.
Avionaut offers two dedicated ISOFIX bases for its infant carriers:
- IQ Orbit – the premium rotating base with intelligent installation technology.
- Dock Base – a simple, secure ISOFIX base designed for straightforward everyday use.
Both provide a fast and secure way to install your infant carrier, but they're designed with different priorities in mind.
The question isn't which one is better.
It's which one is better for your family.
Why Choose an ISOFIX Base?
Although compatible Avionaut infant carriers can be installed using your vehicle's three-point seat belt, a dedicated ISOFIX base offers several important advantages.
Once installed, the base remains securely fixed in your vehicle. Instead of threading the seat belt through the infant carrier every time you travel, you simply click the seat into the base until it locks into position.
For busy parents, that means:
- Faster installation.
- Reduced risk of installation errors.
- Greater day-to-day convenience.
- Improved confidence that the seat has been fitted correctly.
- Less disturbance when moving a sleeping baby.
When you're making multiple journeys every day, those small conveniences quickly become part of everyday family life.
Avionaut IQ Orbit
Premium Innovation for Everyday Parenting
The IQ Orbit is Avionaut's flagship ISOFIX base, created for parents who want the easiest and most intuitive everyday experience.
Compatible with the Pixel 3 and Pixel PRO 2.0 C, the IQ Orbit introduces two features that make it stand out from conventional ISOFIX bases:
Smooth 360° Rotation
The seat rotates effortlessly towards the vehicle door, allowing you to place your baby into the carrier, fasten the harness and lift them out without awkward stretching or leaning into the car.
This is particularly helpful:
- During the newborn months.
- After a Caesarean birth.
- In smaller vehicles.
- When your baby becomes heavier.
- For grandparents and other caregivers.
It's one of those features that parents often don't realise they need until they experience it.
Dual Confirmation Technology
Correct installation is essential for every journey.
That's why the IQ Orbit provides both visual and audible confirmation when the infant carrier has been correctly attached.
Visual indicators allow you to quickly check that everything is locked into place, while an audible click provides immediate reassurance that the seat has engaged correctly.
This dual confirmation system helps reduce uncertainty and gives parents extra confidence every time they set off.
Key Features
- 360° rotation for easier loading and unloading.
- ISOFIX installation.
- Visual installation indicators.
- Audible installation confirmation.
- Premium everyday usability.
- Compatible with Pixel 3 and Pixel PRO 2.0 C.
Avionaut Dock Base
Simple, Secure and Reliable
Not every family needs a rotating base.
Some parents simply want a secure ISOFIX installation that's quick to use, dependable and represents excellent value.
That's exactly what the Dock Base delivers.
Once installed, the Dock Base allows your compatible infant carrier to click securely into place in seconds, removing the need to route the vehicle's seat belt around the seat for every journey.
Like the IQ Orbit, the Dock Base features clear visual installation indicators, helping parents confirm the seat has been correctly fitted before travelling.
Its straightforward design makes it particularly popular as:
- A base for a second family car.
- A grandparent's vehicle.
- A practical choice for parents who don't require rotation.
- An affordable way to enjoy the benefits of ISOFIX installation.
Sometimes, simple really is all you need.
Key Features
- Secure ISOFIX installation.
- Clear visual installation indicators.
- Quick click-in installation.
- Lightweight, durable construction.
- Compatible with Pixel 3, Pixel PRO 2.0 C and Cosmo.*
*Always check compatibility with your chosen infant carrier before purchasing.

Which Base Should You Choose?
The answer depends entirely on how you use your car.
Choose the IQ Orbit if you:
- Use your car every day.
- Want maximum convenience.
- Value the ease of 360° rotation.
- Want both visual and audible installation confirmation.
- Appreciate premium features that make everyday parenting easier.
Choose the Dock Base if you:
- Want secure ISOFIX installation without unnecessary extras.
- Are looking for excellent value.
- Need a base for a second vehicle.
- Prefer a simple, dependable solution.
- Don't feel you'll benefit from a rotating base.
Both bases achieve the same goal—providing a secure connection between your infant carrier and your vehicle. The difference lies in the everyday experience they offer.
Expert Tip
If this is your family's main vehicle and you'll be using your infant carrier every day, the IQ Orbit is well worth considering. The combination of 360° rotation and dual confirmation technology transforms one of the most repetitive parts of parenting into something noticeably easier.
If you're buying a base for a second car or simply want the reassurance of ISOFIX installation at a lower cost, the Dock Base remains an excellent choice.
Our Verdict
Both the IQ Orbit and the Dock Base reflect Avionaut's commitment to thoughtful engineering and child safety, but they serve different needs.
The Dock Base is a dependable, straightforward solution that offers the confidence of ISOFIX installation with clear visual indicators and excellent everyday usability.
The IQ Orbit takes that experience a step further. Its smooth 360° rotation, combined with dual confirmation technology—using both visual and audible indicators—makes loading your baby easier while providing additional reassurance that the seat has been installed correctly.
Whichever base you choose, you're investing in a system designed to make every journey safer, simpler and more enjoyable for both parent and child.

Which Avionaut Car Seat Should You Buy?
Finding the Right Seat for Your Family
After exploring every seat in the Avionaut range, you might still be asking the same question:
"Which one is right for us?"
The truth is, there isn't a single "best" Avionaut car seat.
Each model has been designed to solve a different problem.
Some parents want the lightest infant carrier they can find.

Expert Advice from Baby Boutique UK
If you're still unsure which Avionaut seat is the best fit for your child, we're here to help. Our team can explain the differences between models, discuss compatibility with your vehicle and help you choose a seat that suits both your child's needs and your lifestyle. We believe buying a car seat should feel reassuring—not overwhelming.
Why Choose Avionaut?
What Makes Avionaut Different?
The premium car seat market has never been more competitive.
Parents can choose from dozens of respected brands, each promising exceptional safety, innovative features and premium comfort.
So why do so many families choose Avionaut?
The answer isn't a single feature or marketing slogan.
It's a philosophy.
Rather than trying to manufacture every type of baby product imaginable, Avionaut has built its reputation around one goal:
Designing child car seats that place safety, ergonomics and healthy development at the centre of every decision.
That philosophy is reflected throughout every product in the range—from the lightweight Pixel infant carriers to the Swedish Plus Tested rear-facing seats and the independently tested MaxSpace booster.
Safety Comes Before Marketing
Every car seat sold in the UK must meet the latest R129 (i-Size) regulations before it can legally reach the market.
For Avionaut, that's only the beginning.
Many manufacturers are satisfied once a seat passes the legal approval process.
Avionaut regularly goes further by entering its products into some of Europe's most demanding independent testing programmes, including ADAC and the Swedish Plus Test.
These tests are entirely voluntary.
Manufacturers don't have to take part.
Choosing to do so demonstrates confidence in the engineering behind the product.
Throughout this guide we've seen examples of Avionaut seats achieving impressive independent results, from the Cosmo's outstanding ADAC crash performance to the Swedish Plus Tested Sky 2.0 and Stardust RWF.
Designed With Child Development in Mind
One of the biggest differences you'll notice with Avionaut is that the conversation isn't only about crash protection.
It's also about how children travel every day.
From birth, a baby's spine, muscles and posture are constantly developing.
A well-designed car seat doesn't simply restrain a child during a collision.
It should also provide appropriate support throughout every journey.
That's why Avionaut works with specialists, including physiotherapists, during the development of many of its products.
This collaboration helps shape features such as:
- Ergonomic newborn inserts.
- Natural seating positions.
- Head and neck support.
- Pressure distribution.
- Long-term comfort.
It's a reminder that child safety extends beyond the moment of impact.
Innovation That Solves Everyday Problems
Not every innovation has to be complicated.
Sometimes the best ideas simply make life easier.
Throughout the Avionaut range you'll find thoughtful features designed around everyday parenting.
Examples include:
- Ultra-lightweight infant carriers that reduce lifting strain.
- 360° rotating ISOFIX systems.
- 180° Easy-Access Rotation on the Stardust RWF.
- Intelligent visual and audible installation confirmation.
- Premium breathable fabrics.
- Ergonomic inserts developed for newborn comfort.
These aren't gimmicks.
They're practical solutions designed to improve everyday family life.
A Commitment to Independent Testing
One of the reasons Avionaut has built such a strong reputation among specialist retailers is its willingness to submit products to independent testing.
Independent testing gives parents valuable information that goes beyond manufacturer claims.
For example:
- ADAC evaluates crash performance, ergonomics, ease of use and harmful substances.
- The Swedish Plus Test measures the forces acting on a child's neck during severe frontal collisions.
- R129 ensures every product meets modern European legal requirements.
Rather than relying on a single certificate, Avionaut believes in building confidence through multiple forms of assessment.
Supporting Families Beyond the Product
Earlier in this guide, we explored Avionaut's partnership with Bliss, the UK's leading charity for babies born premature or sick.
That partnership reflects a broader commitment to supporting families—not simply selling products.
Combined with Avionaut's work alongside healthcare professionals and child development specialists, it demonstrates that the company sees child safety as something much bigger than crash testing alone.
It's about giving every child the safest possible start in life.
Built for Every Stage of Childhood
One of Avionaut's greatest strengths is the way its products work together.
Rather than treating each seat as an isolated product, the range has been developed to support families from birth through to approximately twelve years of age.
Whether you're choosing:
- Pixel 3.
- Pixel PRO 2.0 C.
- Cosmo.
- Sky 2.0.
- Stardust RWF.
- Stardust 360.
- MaxSpace.
You'll find the same design philosophy running throughout the range.
Premium engineering.
Thoughtful ergonomics.
Independent safety credentials.
And a clear focus on protecting children during every stage of their journey.
Why Parents Choose Avionaut
Parents consistently tell us they choose Avionaut because they value:
✔ Independent safety testing.
✔ Premium European engineering.
✔ Lightweight, practical designs.
✔ Ergonomic support for growing children.
✔ Excellent build quality.
✔ Long-term comfort.
✔ Innovation that genuinely improves everyday family life.
It's these qualities that have helped Avionaut become one of Europe's fastest-growing premium child car seat brands.
Is Avionaut the Right Brand for You?
If you're looking for the cheapest car seat available, there are plenty of alternatives.
But if you're looking for a brand that combines thoughtful engineering, independent safety credentials and a genuine commitment to child development, Avionaut deserves a place on your shortlist.
Every family is different.
Every journey is different.
That's why Avionaut offers a carefully considered range rather than a one-size-fits-all solution.
Whether your priority is the lightest infant carrier, extended rear-facing travel, a rotating all-stage seat or a premium booster, there's an Avionaut model designed with that purpose in mind.
Our Final Thoughts Before the FAQ
By now, you've met every seat in the Avionaut family, explored the different ISOFIX bases and learned about the independent testing that underpins the brand's reputation.
There's only one thing left to do.
Answer the questions parents ask most often.
In the final chapter, we'll tackle everything from "Is Avionaut better than Cybex?" to "How long should my child stay rear-facing?", giving you clear, evidence-based answers to help you make your final decision.
Your Avionaut Questions Answered
Everything Parents Want to Know Before Buying
Buying a child car seat is a significant decision, and it's completely natural to have questions before making your choice.
Throughout this guide we've explored every model in the Avionaut range, explained independent safety testing and compared the different seats available.
This chapter brings everything together by answering the questions we're asked most often by parents both online and in store.
Whether you're choosing your very first infant carrier or deciding between two different models, we hope these answers help you make your decision with confidence.
Is Avionaut a Good Car Seat Brand?
Yes.
Avionaut has built an excellent reputation across Europe for designing premium child car seats that combine advanced engineering with a strong focus on ergonomics and child development.
Unlike many manufacturers that produce a wide range of baby products, Avionaut specialises in child car seats. That specialist approach allows the company to focus its research and development on improving child safety, comfort and everyday usability.
Many Avionaut products have also undergone independent testing through organisations such as ADAC, while selected rear-facing seats have achieved the prestigious Swedish Plus Test certification.
Is Avionaut Better Than Cybex?
There isn't a single answer because both brands produce excellent products.
The biggest difference lies in philosophy.
Cybex is well known for combining innovative design with premium safety features across a very broad product range.
Avionaut focuses almost exclusively on child car seats, placing particular emphasis on ergonomics, lightweight construction and extended rear-facing travel.
If your priority is specialist child seat engineering and thoughtful ergonomics, Avionaut is an outstanding choice.
Is Avionaut Better Than Maxi-Cosi?
Both brands manufacture high-quality car seats that meet the latest R129 safety regulations.
Maxi-Cosi has one of the widest product ranges in the industry.
Avionaut offers a smaller, more focused collection, with particular attention given to ergonomics, lightweight infant carriers and independent safety testing.
Rather than asking which brand is better, it's more helpful to compare the individual models that best suit your child's age and your family's lifestyle.
Why Are Avionaut Infant Carriers So Light?
Reducing weight has been one of Avionaut's design priorities for many years.
Rather than relying on heavier construction, the company uses advanced materials and carefully engineered structures to minimise unnecessary weight without compromising safety.
The result is infant carriers that are significantly easier to carry while still meeting the latest European safety standards.
For parents lifting a growing baby several times a day, those weight savings quickly become noticeable.
Which Is Better: Pixel 3 or Pixel PRO 2.0 C?
Both are premium infant carriers, but they're designed for slightly different parents.
Choose the Pixel 3 if you want Avionaut's latest generation infant carrier with the newest design refinements and compatibility with the IQ Orbit base.
Choose the Pixel PRO 2.0 C if your priority is carrying one of the lightest premium infant carriers available and you want a model with an established ADAC result.
Neither is the wrong choice.
Both are excellent.
Should I Buy the Pixel 3 or the Cosmo?
The decision comes down to priorities.
The Pixel 3 offers Avionaut's newest generation of design and premium features.
The Cosmo offers exceptional value while achieving outstanding independent crash performance in ADAC testing.
If your budget allows and you want the newest model, choose the Pixel 3.
If your priority is value combined with excellent safety credentials, the Cosmo is one of the strongest options available.
Is the IQ Orbit Worth the Extra Money?
For many families, yes.
The IQ Orbit doesn't simply provide ISOFIX installation.
It adds features that improve everyday life, including:
- Smooth 360° rotation.
- Visual installation indicators.
- Audible confirmation when the seat is correctly attached.
Parents often tell us the rotating function quickly becomes one of their favourite features because it makes lifting a baby into and out of the vehicle much easier.
If you travel frequently, it's an investment many families feel is worthwhile.
Do I Need an ISOFIX Base?
No.
Compatible Avionaut infant carriers can also be installed using your vehicle's three-point seat belt.
However, an ISOFIX base offers:
- Faster installation.
- Reduced chance of installation errors.
- Greater convenience.
- Easier everyday use.
For families making regular car journeys, an ISOFIX base is often a worthwhile investment.
How Long Should My Child Stay Rear-Facing?
The simple answer is:
For as long as your chosen rear-facing seat allows.
Rear-facing seats help distribute crash forces across a child's back, shoulders and head, reducing the forces placed on the neck during a frontal collision.
Many child safety experts recommend keeping children rear-facing for as long as possible, provided they remain within the height and weight limits specified by the manufacturer.
Is Swedish Plus Better Than ADAC?
This is one of the most misunderstood questions in child passenger safety.
The answer is:
They measure different things.
The Swedish Plus Test focuses almost entirely on the forces acting on a child's neck during a severe frontal collision.
ADAC evaluates a much broader range of factors, including:
- Crash performance.
- Ease of use.
- Ergonomics.
- Installation.
- Harmful substances.
Neither test replaces the other.
Together, they provide parents with a much more complete picture of a car seat's performance.
Why Doesn't the Stardust 360 Have Swedish Plus Test Certification?
Not because it failed.
Because it isn't eligible.
The Swedish Plus Test is only open to rear-facing-only seats.
The Stardust 360 eventually allows forward-facing travel, which automatically excludes it from the programme.
That doesn't mean it isn't a safe seat.
It simply has a different purpose.
Is the Stardust RWF Safer Than the Stardust 360?
Both seats meet the latest R129 safety regulations.
The difference lies in how they're designed.
The Stardust RWF has been engineered exclusively for rear-facing travel and has achieved Swedish Plus Test certification.
The Stardust 360 has been designed as an all-stage seat that offers greater flexibility and everyday convenience through full 360° rotation.
The better seat depends on your priorities rather than one being universally safer than the other.
Which Avionaut Seat Lasts the Longest?
The Stardust 360 has the longest usable lifespan in the current Avionaut range.
Suitable from 40cm to 150cm, it supports children from birth through to approximately twelve years of age.
Can I Use an Avionaut Infant Carrier as Part of a Travel System?
Yes.
Avionaut infant carriers are compatible with a wide range of leading pushchair brands when used with the correct adapters.
Always check compatibility with your chosen pushchair before purchasing.
Which Avionaut Seat Is Best for Premature Babies?
Every baby's needs are different, particularly if they are born prematurely or have ongoing medical needs.
Avionaut has worked with physiotherapists during the development of its infant carriers and supports Bliss, the UK's leading charity for babies born premature or sick. W would recommend the Pixel 3.
If your baby has been born prematurely, always follow the advice provided by your neonatal team or healthcare professionals when selecting and using a car seat.
Our Final Advice
Every family's needs are different.
Some parents will value lightweight design above everything else.
Others will prioritise Swedish Plus Test certification or the convenience of 360° rotation.
There is no single "best" Avionaut car seat.
Only the one that's right for your child, your vehicle and the way your family travels.
Taking the time to understand the differences between each model is one of the best investments you can make before welcoming your child into the world.
Which Avionaut Car Seat Is Right for You?
If you've made it this far, you've probably realised something important.
Choosing a car seat isn't about finding the most expensive model, the one with the most features or even the one with the highest independent test score.
It's about choosing the seat that's right for your child, your vehicle and your family's lifestyle.
Throughout this guide we've explored every seat in the current Avionaut range, explained the meaning behind independent safety testing and looked beyond marketing claims to understand what really matters when transporting your child safely.
One thing has become clear.
Avionaut doesn't believe every family needs the same car seat.
Instead, each model has been carefully designed to solve a different challenge.
Whether that's carrying a newborn more comfortably, keeping a child rear-facing for longer or providing a premium booster for older children, every product has a clear purpose.
