The Avionaut MaxSpace Smart child seat is an innovative solution for the safety and comfort of children aged 3.5 to 12 years. With a height of 100 to 150 cm and a weight of 15 to 50 kg, this child seat not only offers protection, but also promotes a healthy sitting posture. The lower seat surface supports a natural pelvic contour, which prevents back pain and contributes to a healthy musculoskeletal system. The one-hand height-adjustable headrest and the practical adjustment indicator allow the seat to be customised to the child's height. In addition, the backrest angle can be adjusted to a reclined position, which promotes a relaxed sleeping position. The sturdy hip belt guides and side supports offer additional protection in the event of a collision, while the leather armrests increase seating comfort. The MaxSpace Smart is easy to install in the vehicle, either with Isofix or the 3-point harness, and fulfils the requirements of the ECE R129/03 standard, making it a safe choice for parents.
