Isofix is a standard system for installing child car seats in vehicles. It is designed to make installation easier, quicker and safer. Isofix car seats are attached directly to the car's chassis using two anchor points and a top tether strap, rather than relying on a seatbelt to hold the car seat in place. The Isofix anchor points are built into the car's seat structure and can be found in the gap between the backrest and the seat cushion. This system ensures that the car seat is securely attached to the car, reducing the risk of incorrect installation and improving the safety of the child.
