Best Swedish Plus Tested & Rear Facing Car Seats UK (2026 Guide)

Best Swedish Plus Tested Car Seats UK (2026 Guide)

When it comes to child car seat safety, few certifications are as respected as the Swedish Plus Test. This independent crash test is widely considered the toughest car seat safety standard in the world, focusing on the forces placed on a child’s neck during a collision.

Unlike standard European testing, the Swedish Plus Test only approves car seats that offer exceptional protection in severe frontal crashes. Because of this, only rear-facing car seats pass the test.

For parents looking for the safest option for their child, choosing a Swedish Plus Tested car seat is one of the best decisions you can make.

In this guide, we explain what the Swedish Plus Test means and highlight some of the best Swedish Plus Tested car seats available in the UK.


What Is the Swedish Plus Test?

The Swedish Plus Test is an independent crash test developed in Sweden and conducted by VTI (the Swedish National Road and Transport Research Institute).

The test measures the forces placed on a child’s neck during a frontal crash. If the forces exceed safe limits, the seat automatically fails.

Because forward-facing seats place significantly higher forces on a child’s neck, only rear-facing seats can pass this test.

For parents, this means Swedish Plus Tested seats offer some of the highest levels of protection available.


Why Rear Facing Car Seats Are Safer

Research consistently shows that rear-facing car seats provide superior protection for young children.

In a frontal collision, a rear-facing seat distributes crash forces across the back of the seat rather than concentrating them on the neck and spine.

This dramatically reduces the risk of serious injury.

Safety experts recommend children remain rear-facing for as long as possible, ideally until at least 4 years old — and many extended rear-facing seats allow travel up to 6–7 years.

FAQ – Swedish Plus Tested Car Seats

Are Swedish Plus Tested car seats the safest?

They are widely considered among the safest because the test measures neck forces in severe frontal collisions.

Can forward-facing car seats pass the Swedish Plus Test?

No. Only rear-facing car seats pass the Swedish Plus Test.

What age can children stay rear facing?

Many extended rear-facing seats allow travel until 6–7 years old.

What Is an Extended Rear-Facing Car Seat?

An extended rear-facing car seat (ERF) allows children to travel rear-facing for far longer than standard car seats.

While many traditional car seats turn forward-facing around 12–15 months, extended rear-facing seats allow children to travel rear-facing until 4, 5, or even 7 years old depending on the model.

Rear-facing travel is widely considered the safest way for children to travel because it reduces the forces placed on the neck and spine during a collision.

Many of the safest rear-facing car seats in the UK are also Swedish Plus Tested, meaning they have passed one of the toughest crash tests in the world.

Examples of extended rear-facing car seats include:

• Axkid Minikid Core
• Axkid Minikid 4 Max
• Avionaut Sky
• Avionaut Stardust RWF+

These seats allow families to keep their child rear-facing for significantly longer, providing additional safety during the early years of travel.
