The set consists of a seat, back cushion and 3-point belt incl. Fidlock magnetic buckle. The seat is made of EPP foam and the seat surface is finished with embedded cellular rubber for the best possible seating comfort. The back cushion is high enough to allow children of different heights to sit comfortably and relaxed. The harness is secured to the CAB at three points: a short harness including the buckle is fixed to the floor. The two shoulder straps are secured at the back of the CAB in the holders provided. There are six holders at different heights so that the harness can be adjusted to the size of the child. The Fidlock magnetic buckle is easy for parents to operate, but not easy for passengers to open on their own. The special feature: the short belt and buckle are fed through the opening provided in the seat and hold it securely in place. At the same time, the seat can be removed quickly and without tools if something other than your little one needs to be transported.
