Avionaut MaxSpace Smart i-Size High Back Booster Car Seat – Grey

The Avionaut MaxSpace Smart i-Size High Back Booster Car Seat is a premium forward-facing booster seat designed to support your child’s comfort, posture, and safety as they grow. Suitable from 100 to 150 cm (approx. 3 to 12 years), it offers a long-lasting solution for the final stage of car seat use. Featuring refreshed upholstery, ergonomic design, and proven i-Size safety, the MaxSpace Smart delivers reliable everyday protection with a strong focus on healthy spinal support.

Built to the ECE R129/03 i-Size safety standard, the MaxSpace Smart includes an additional side impact protection system to enhance safety in the event of a collision. Designed with ergonomics at its core, this booster promotes correct posture throughout every stage of development, helping to support your child’s spine on every journey.

Thanks to its backrest tilt function, the MaxSpace Smart can be adjusted into a comfortable resting position—ideal for naps on longer journeys. This rare feature helps prevent the child’s head from falling forward while sleeping, improving comfort and reducing fatigue during travel.
