Car Seats
Choose the correct car seat
Children must normally use a child car seat until they're 12 years old or 135 centimetres tall, whichever comes first. Children over 12 or more than 135cm tall must wear a seat belt. You can choose a child's car seat based on your child's height or weight.
Height-based seats
Height-based seats are known as 'i-Size' seats. They must be rear-facing until your child is over 15 months old. Your child can use a forward-facing child car seat when they're over 15 months old. You must check the seat to make sure it's suitable for the height of your child. Only EU-approved height-based child car seats can be used in the UK. These have a label showing a capital 'E' in a circle and 'R129'.
Weight-based seats
The seat your child can use (and the way they must be restrained in it) depends on their weight. Only EU-approved weight-based child car seats can be used in the UK. These have a label showing a capital 'E' in a circle and 'ECE R44'. You may be able to choose from more than one type of seat in the group for your child's weight.
Manufacturers can now only make booster cushions approved as group 3. This won’t affect any existing booster cushions in group 2 and you’ll still be able to use them.
