Nuna ARRA™ Flex Car Seat – Chateau

Flat Recline i-Size Infant Car Seat | Birth to 13kg

Introducing the Nuna ARRA™ Flex Car Seat in Chateau – a beautifully crafted infant carrier designed for parents who want ultimate comfort, advanced safety, and effortless flexibility from day one. Finished in Nuna’s elegant Chateau neutral tone, this warm, sophisticated colourway blends seamlessly into modern lifestyles while delivering the premium performance Nuna is known for.

From quick errands to long-distance journeys, the ARRA Flex allows you to move from car to pushchair to carry mode without disturbing your baby, making everyday travel simpler and more comfortable.

A Warm, Timeless Neutral – Chateau

The Chateau colourway features a soft, warm neutral tone inspired by natural textures and calming interiors. Perfect for parents looking for a beige / taupe aesthetic, it pairs effortlessly with a wide range of pushchairs while offering a lighter, more contemporary alternative to black.

✨ Ergonomic Comfort for Longer Journeys

At the heart of the ARRA Flex is its 157° near-flat recline, allowing your baby to lie in a more natural position that supports healthy spine, hip, and head development.

Unlike traditional infant carriers, this innovative design makes the ARRA Flex suitable for longer journeys, giving parents greater freedom when travelling.

With three recline positions, your baby stays comfortable whether in the car, attached to your pushchair, or carried on the go.

Flexible Installation for Everyday Life

The ARRA Flex is designed to fit around your lifestyle, offering multiple installation options:

• Compatible with Nuna BASE™ next and BASE™ curv (360° rotating ISOFIX bases)

• Secure vehicle seat belt installation – ideal for taxis or second cars

• Travel system ready with Nuna pushchairs

• TÜV aircraft certified – safe for use on aeroplanes

Part of Nuna’s NEXT™ system, it integrates seamlessly into a modular travel solution for your child’s early years.

• EPP energy-absorbing foam for enhanced side impact protection
