Nuna ARRA™ Flex Car Seat – Chestnut

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

Introducing the Nuna ARRA™ Flex Car Seat in Chestnut – a beautifully designed infant carrier created for parents who want superior comfort, advanced safety, and everyday flexibility from day one. Finished in Nuna’s rich Chestnut colourway, this warm, earthy tone adds a luxurious feel while maintaining a timeless, neutral look that complements any pushchair or travel system.

From quick trips around town to longer journeys, the ARRA Flex allows you to move effortlessly from car to pushchair to carry mode without disturbing your baby, making everyday travel smoother and more convenient.

A Rich, Warm Neutral – Chestnut

The Chestnut colourway features a deep, earthy brown tone inspired by natural materials and modern interiors. Perfect for parents looking for a warmer alternative to black or grey, it offers a premium, sophisticated look while remaining practical for everyday use.

✨ Ergonomic Comfort for Every Journey

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

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

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

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

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

• Travel system ready with Nuna pushchairs

• TÜV aircraft certified – suitable for air travel

Part of Nuna’s NEXT™ system, it provides a flexible, modular solution that grows with your child.
