Flat Recline i-Size Infant Car Seat | Birth to 13kg
Meet the Nuna ARRA™ Flex Car Seat in Caviar – a beautifully engineered infant carrier designed for modern parents who want maximum comfort, flexibility, and safety from day one. Finished in Nuna’s signature Caviar black, this premium car seat combines sleek styling with cutting-edge ergonomic design, making every journey smoother for both you and baby.
Whether you're heading out for a quick trip or a long-distance journey, the ARRA Flex transitions effortlessly from car seat to travel system to carry mode, keeping your baby comfortable without disruption.
What sets the ARRA Flex apart is its 157° near-flat recline, allowing your baby to lie in a more natural position – ideal for healthy spine, hip and head development. Unlike traditional infant carriers, this means it’s exempt from the usual 2-hour usage guideline, making it perfect for longer days out.
With 3 recline positions available both in the car and on your pushchair, your baby stays comfortable wherever your journey takes you.
Designed to fit seamlessly into your lifestyle, the ARRA Flex offers multiple installation options:
Compatible with Nuna BASE™ next and BASE™ curv (360° rotating ISOFIX bases)
Secure vehicle seat belt installation – no base required
Travel system ready with Nuna pushchairs
TÜV aircraft certified – safe for air travel
It’s part of Nuna’s NEXT™ system, giving you a modular solution that grows with your child.
Built to exceed the latest i-Size (R129) safety standards, the ARRA Flex is packed with innovative safety features:
EPP energy-absorbing foam for superior side impact protection
Tailor tech™ memory foam headrest for a custom, secure fit
High-strength shell and handle design to protect baby’s head and body
Side impact tested for complete peace of mind
Every detail of the ARRA Flex is designed with comfort in mind:
Lightweight design (just 3.8kg) – easy to carry and lift
Removable newborn insert with Merino wool & TENCEL™ for breathable softness
10-position adjustable headrest – grows with your baby
UPF 50+ canopy with mesh window and flip-out eyeshade
Luxe leatherette carry handle for a premium feel
