Backless booster seats are temptingly cheap - some start from as little as £6 - legal to sell and use, and there's no doubt they're convenient.
But while using any child car seat is better than using none, booster seats offer very little protection in a crash, particularly if you're hit from the side.
In February 2021, we surveyed 2,021 parents who have a child or children under 12 years old and asked them whether they think backless booster seats offer the same crash protection as high-backed booster seats.
More than a third of parents (37%) think that they do.
Read on to find out what the issues are with backless booster seats and our advice on the best type of car seats to use for older children.
The video below shows what happened in a crash test to a child sitting on a backless booster seat.
We'd always advise using a high-back booster seat when travelling in a car. Here's why:
A backless booster seat will raise your child's body to a height suitable for use with the adult seat, but it makes it more difficult to correctly position the diagonal strap of a three-point adult seat belt across the shoulder.
This can mean there's nothing to stop your child from slamming into the side of the vehicle, seriously injuring themselves.
We've tested and reviewed nearly 35 high-back booster seats and found seven Best Buys, including one that costs £90 and can be used from four to 12 years old.
