Question: what is the difference between group 2 and 3 car seat?
Answer: Group 1, 2 and 3 seats are forward-facing. The child uses the seat's integral harness, or an impact cushion, until they are 15 kg and then uses the car's seat belt, which secures the child and the seat. Group 2 and 3 seats are high-backed booster seats, although they can also be booster cushions without a back.
