Group 0
Birth to 10kg This is a car bed, which is suitable for the first six months. They are particularly good for premature babies who can suffer breathing difficulties in more upright seats. They take up two spaces in the car as they are installed sideways. Not many manufacturers make these car beds anymore, and unless the baby needs one for medical reasons, we believe that travelling backwards is safer than travelling sideways.

Group 0+
Birth to 13kg Rear facing infant carrier car seat, for babies from birth up to about 18 months.
Seats like this can be used until the top of the baby's head is level with the top edge of the seat. |
Group 1
9-18kg Car seat with a five-point harness, for children aged approximately 9 months to 4 years. There are no rear facing seats available that are Group 1 only, extended rear facing seats are all combination seats which cover more than one group, which is why we used a picture of a forward facing one here. Both rear and forward facing Group 1 seats can be used until the child's eye line is level with the top edge of the seat or the shoulders no longer fit under the headrest.
|
Group 2-3
15-36kg Seat belt positioning high back booster seat. The head rest can be moved up to grow with the child, and in some models the sides move outwards to give a bigger child's shoulders more room. These seats are for children aged 4 to 12. In some models the back can be removed to leave a booster cushion.
|
Group 3
22-36kg Seat belt positioning booster cushion. There are no seats that only cover Group 2 or Group 3, high back boosters as well as booster cushions are Group 2-3, which means these cushions are also suitable from 4 to 12 years. But they offer no side impact protection, and no comfort for a small child, which is why we have just called this Group 3. Since early 2017 all new booster cushions have been approved for Group 3 only, and must only used by children who are taller than 125cm and weigh more than 22kg. |
Some babies are very big and reach 9kg when they are very young. But even if they are big and appear 'strong', their skeleton is not mature enough to support their heavy head in a crash. Even the nine month minimum forward facing age that manufacturers give is far too young. The bones in a child's neck don't begin to fuse until they are two or three years old, and it takes about three years for this process to complete. So it isn't actually until they are six that their neck is strong enough to cope with the forces of a car crash. This is why it is important for children to travel rear facing for as long as possible.
When this picture was taken this 93rd percentile baby was six months old. He already weighed 9.5kg, so legally he was 'heavy enough' to face forward. A perfect example of the fact that legal doesn't necessarily mean safe... (This car seat was a combination one which he only used rear facing.) |
Group 0-1
Rear facing from birth to 18kg, forward facing from 9-18kg
|
Group 0-1-2
Rear facing from birth to 25kg, forward facing from 9-25kg
|
Group 0-1-2-3
Rear facing from birth to 18kg, forward facing with the five-point harness from 9-18kg, high back booster from 15-36kg.
|

|
Group 1-2-3
Forward facing with an impact shield from 9-18kg, high back booster from 15-36kg.
Impact shields are not as safe as seats with a five-point harness and we do not recommended them. |
|

All car seats have an orange approval sticker, usually on the back. This sticker tells you whether the seat meets R44/04 or i-Size, it gives the weight and height limits, and the seat's approval number. The circle with the E in it indicates that the seat is approved for use in Europe and the number is the country it was tested in. For example 1 is Germany, 4 is the Netherlands, 5 is Sweden, 11 is the UK, etc. Each country has its own number, but seats from any European country may be used in any other. It will say Universal meaning the seat will fit in most cars, or Semi-Universal if they have a support leg which you may not be able to use if your car has storage compartments in the footwell. The Y indicates that the seat has a harness with a crotch strap.
Seats bought outside Europe which do not have this sticker are not legal in Europe and must not be used here. |
The law says that children need to use a car seat until they are either 12 years old or 135cm tall. Seat belts are designed for adults and don't fit children properly. That is why older children need to sit in booster seats which guide the shoulder belt away from their neck, and the lap belt down from their abdomen onto their pelvis. If a child is 12 years old, but under 135cm tall, it is still safer for them to sit on a booster cushion. The 36kg weight limit is just given as an average. In the unlikely event that a child weighs over 36kg, but is still under 135cm, it is safer to stay on the booster until they have grown a bit taller.
On average children reach 135cm at about nine and a half, only children on the 2nd percentile take 12 years to reach that height. 150cm is more realistic for a 12 year-old and most boosters will fit up to 150cm. Don't be in a rush to stop using the booster as soon as your child hits 135cm, because that is often still too short for the adult seat belt to fit them safely. |
