A car seat is an essential for most parents but choosing one is not just a matter of personal preference. Here’s everything you need to know.
Unlike buying a playhouse or a scooter for your child, you don’t have complete free will when it comes to selecting a car seat. You can choose the make and model that suits you / your child best, but fundamentally there are laws around car seats that you have to follow. What’s more, these legal requirements change as your child gets older.
What's the law?
The law says that your child must be:
- In a car seat until the age of 12 or until they reach 135cm in height, whichever comes first.
- The seat also has to meet EU safety standards - shown by an E on the label. Of course, if you’re buying from a reputable dealer it will almost certainly meet these regulations, but check to make sure.
- You also need to make sure the seat is the right type for your child’s age and size. The car seat must be rear facing until your child is 15 months old.
Car seats are split into categories from 0 to 3, representing different weights (a no:1 seat is for children between 9 and 18kg, for example). This Government web page explains a little more about what the numbers mean, but the main details are in the table below.
Some car seats cover more than one category, and you can buy seats that adjust to cover them all.
GROUP | CHILD'S WEIGHT | SEAT TYPE |
|---|---|---|
Group 0 | 0kg to 10kg | Lie-flat or ‘lateral’ baby carrier, rear-facing baby carrier, or rear-facing baby seat using a harness |
Group 0+ | 0kg to 13kg | Rear-facing baby carrier or rear-facing baby seat using a harness |
Group 1 | 9kg to 18kg | Rear- or forward-facing baby seat using a harness or safety shield |
Group 2 | 15kg to 25kg | Rear- or forward-facing child car seat (high backed booster seat or booster cushion) using a seat belt, harness or safety shield |
Group 3 | 22kg to 36kg | Rear- or forward-facing child car seat (high-backed booster seat or booster cushion) using a seat belt, harness or safety shield |
Before shopping for a car seat, check your child’s weight and height. That will give you the information you need to buy the right car seat to keep them both comfortable and safe.
Finally, never buy a second hand car seat - it may have wear and tear and may even have been weakened or damaged in an accident.
What else to look out for?
As well as the law and checking your child's weight, there are a few other things to consider when you're buying a baby car seat:
It fits the car.
Most modern seats will fit in most modern cars, but it’s best to check to make sure. Remember that you may be using the seat not just in your own car, but in - for example - a grandparent’s car too.
The right seat fit.
Be confident that you can fit the seat properly. A seat is only safe if it has been fitted correctly, so follow all instructions carefully. These Which? videos (rear facing, forward facing) should help.
What accessories do you need.
As with all things, more expensive models tend to have more accessories. For example, you may think it worth splashing out for a sunshade, cup holder or mirror (so you can see your baby’s face in a rear facing seat).
