Flat Recline i-Size Infant Car Seat | Birth to 13kg
Introducing the Nuna ARRA™ Flex Car Seat in Pistachio – a beautifully refined infant carrier designed for modern parents who want ergonomic comfort, advanced safety, and effortless flexibility from day one. Finished in a soft, nature-inspired Pistachio green, this contemporary colourway brings a fresh, calming aesthetic to your travel system while maintaining Nuna’s signature premium look.
Designed for real life, the ARRA Flex offers a seamless transition from car seat to pushchair to carry mode, keeping your baby comfortable and undisturbed wherever the day takes you.
The Pistachio colourway is a soft, muted green tone that feels both on-trend and timeless. Perfect for parents looking for something lighter than black but still beautifully neutral, it pairs effortlessly with a wide range of pushchairs and accessories.
At the heart of the ARRA Flex is its 157° near-flat recline, allowing your baby to lie in a more natural, ergonomic position – ideal for healthy spine, hip, and head development.
Unlike traditional infant carriers, this design supports longer, more comfortable journeys, making it perfect for busy days, travel, and everyday life.
With three recline positions, your baby stays supported whether in the car, on a pushchair, or on the move.
The ARRA Flex adapts to your lifestyle with multiple installation options:
ISOFIX compatible with Nuna BASE™ next or BASE™ curv
Vehicle seat belt installation – no base needed
Travel system ready – easily attaches to Nuna pushchairs
TÜV aircraft certified – safe for use on aeroplanes
Part of Nuna’s NEXT™ system, it offers a modular solution designed to grow with your child over the first four years.
Safety is at the core of every Nuna design. The ARRA Flex is:
i-Size approved (R129) with side impact testing
Equipped with EPP energy-absorbing foam for enhanced protection
Featuring a Tailor tech™ memory foam headrest for a secure, custom fit
Built with a high-strength protective shell and handle system
Every detail is engineered to provide maximum protection and peace of mind.
From newborn to toddler, the ARRA Flex is designed for everyday comfort:
Lightweight at just 3.8kg – easy to carry and lift
Removable newborn insert with Merino wool & TENCEL™ for breathable softness
10-position adjustable headrest to grow with your baby
UPF 50+ canopy with mesh window and flip-out eyeshade
Luxury leatherette carry handle for a premium finish
The result is a car seat that feels as good as it looks – for both parent and baby.
