The Cybex Aton S2 i-Size car seat grows with your baby by allowing you to adjust the headrest to 11 different heights. In the car, the safety seat is mounted on the Cybex Base One ISOFIX base (not included), or using the seatbelt.

The baby seat complies with the latest safety standard UN R129 (i-Size) and features L.S.P. linear side impact protection. The extending protectors on both sides reduce the impact force by 25% and direct it away from the child.
