The Nuna ARRA Flex Thunder i-Size child car seat is designed to provide advanced safety and outstanding comfort from the very first days of life. It is suitable for children with a height from 40 to 87 cm (from birth up to about 24 months / maximum weight 13 kg). It is certified according to the ECE R129/03 (i-Size) standard, focusing on enhanced protection of the head, neck, and spine, through additional tests for front, side, and rear impact. It is used exclusively rear-facing, recommended up to at least 15 months, for significantly better protection in the event of an accident.
The ARRA Flex stands out for its ergonomics and adaptability: it offers 3 recline positions, with a maximum angle of 157°, ideal both in the car and when the seat is mounted on a stroller, supporting a healthy posture for the spine and breathing. The headrest adjusts to 10 positions with one hand, and the side impact protection contributes to a safer journey. Premium materials in the head support and surface area include ecological Merino wool and TENCEL fibers, gentle on the baby’s skin and naturally managing moisture.
Installation is flexible, depending on the family’s needs: either with the ISOFIX next i-Size base (sold separately) for quick placement, or with the car’s seat belt, offering clearly defined guides and installation indicators. All covers and extra cushions are removable and washable for easy maintenance. The large, extendable canopy with UPF50+ protection and viewing window, as well as the carrying handle with elegant eco-leather finish, complete a premium product compatible with Nuna strollers. Dimensions: L 72–79 x W 43.5 x H 58.5 cm; weight: 3.9 kg (without canopy or newborn insert).
