Want the safest child car seat for your baby?

Sign up for a £1 trial to Which? and discover our expert reviews of the latest child car seats.

Which? is the only review website that tests the child car seats it reviews in simulated car crashes. Our crashes push a car seat further than the safety standard required for a car seat to be sold in Europe. Our experts also try them out in real cars to find out how easy they are to install and whether they are practical and easy to use.

Which? spends more than £45,000 each year testing child car seats.

Our more stringent tests differ from the legal requirement ECE R44/04 in several key ways:

  • Our front crash test is carried out at a higher speed than ECE R44 - about 40mph instead of 30mph.
  • We include a side impact crash test, which ECE R44 does not require.
  • We test child car seats in a real car body, not on a sledge with a car bench seat fixed to it, so the position of the seat belt anchorage points and car seat characteristics are more realistic.

We believe our tests are more representative of real-life crash situations and that choosing a Which? Best Buy child car seat will give your child the best crash protection that money can buy.

You cannot know how a car seat will perform in a crash situation just by looking at it, so find out which child car seats we recommend with a £1 trial to Which?.
