Our comfort insert with extra padding helps to reduce the potential space between small children and the sides of the car seat, and provides additional comfort. It can be used for ECE R44 car seats with an integral harness from 9 kg, and for ECE R129 (i-Size) approved car seats with an integral harness from 60 cm rearward facing or 76 cm forward facing. The comfort insert does not replace a newborn insert and must not be used in infant carriers.
