Group 0/1 car seat

Group 1

Group 1 is the follow-on car seat from group 0+. They are for children aged between 9 months and 4 years old.

Features:

These seats still tend to be bucket shaped and are usually front-facing seats designed for comfort and safety.

Group 1 car seat

Group 1/2/3

Things to consider:

Group 1/2/3 car seats are only suitable for children over nine months old.
