Rules around child car seats are set to change later this year.

Backless booster seats will then be limited to older children.

Here's everything you need to know about the changes:

What's changing?

Which? has reported that regulations will change later this year and the backless seats will only be for children who are taller than 125cm and weigh more than 22kg.

Why are the rules changing?

The consumer watchdog said backless booster seats, also known as booster cushions, were "temptingly cheap to buy" but it did not recommend them.

Which? child car seat expert Lisa Galliers said: "A decent high-backed booster seat provides better protection in a front crash, as they're designed to guide the adult seat-belt across the child's body properly, and our crash tests prove they offer much more protection in a side-impact crash that a backless booster seat alone."

When are the rules changing?

The extra rules are expected to be introduced in December 2016 and will apply to new products on the market.

What if I put my child in a backless booster anyway?

The penalty for breaking rules is a fine of up to £500.
