Are parents getting the message about backless booster seats?

Which? survey discovers backless booster seats are still popular but less so than a few years ago

Are parents getting the message about backless booster seats?

Parents are continuing to use backless booster seats, a Which? survey has found, but significantly less than they were a few years ago.

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 March 2019, we surveyed 3,286 parents who have a child or children under 12 years old and asked them whether they use a backless booster seat.

16% of them told us they do.

Back in 2015, 26% of parents answered yes to the same question.

Why we recommend high-backed boosters

We’d always advise using a high-back booster seat when travelling in a car. Here’s why:

  • A high-back booster seat has a supportive full-length back, side wings and a headrest, which provide extra protection for your child’s head and torso.
  • It also holds your child securely in the seat thanks to the upper belt guide.

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 40 high-back booster seats and found 13 Best Buys, including one that costs just £80 and can be used from four to 12 years old.

Nearly half of all parents don’t know the risks

Our survey also asked parents whether they think backless booster seats offer the same crash protection as high-back booster cushions.

A worrying 18% told us they believed both were equal in terms of safeguarding your child in the event of a collision, and 27% didn’t know either way.

The law and backless booster seats

  • UK law dictates that children must use a child car seat until they’re 12 years old or 135cm/4ft 5in tall, whichever comes first.
  • From 1 March 2017 the rules on backless booster seats changed. These seats can now only be made for children taller than 125cm and weighing more than 22kg.
  • However, backless booster seats made and bought before this date are still legal and approved for use by children weighing between 15kg and 36kg.
  • So, if you own a backless booster seat bought before this date, you can still use it for a child within this weight range.
  • Shops can also sell backless booster seats that are approved for use by children weighing between 15kg and 36kg, so you’ll need to check the label when you buy a seat.
  • Check the label on your booster seat corresponds with the size of your child.
