Maxi-Cosi's new tool will show you the car seats best suited to your child and vehicle

Child car seat brand Maxi-Cosi has launched a new tool that shows you which Maxi-Cosi car seats are suitable for your car, child and preferences.

The new tool, which can be found on Maxi-Cosi's UK website, starts by asking you the height or length of your child. You are then asked a series of questions including whether you want a belted, Isofix or iSize child car seat and, depending on your child's size, whether you want a forward-facing or rearward-facing seat. The site then presents you with the Maxi-Cosi seats that match your preferences.

There are also choosing tools available for Britax child car seats and Recaro child car seats - but before buying any child car seat, it's vital that you check our child car seat reviews to see whether the seat has passed our rigorous safety tests, which are stricter than those required by UK law. Not all Maxi-Cosi car seats have excelled in our safety tests - the scores range from an excellent 82% down to a pretty poor 53%. Head to all of our Maxi-Cosi car seat reviews to find out which came out on top.

How to fit your child car seat correctly

A staggering 51% of child car seats are fitted incorrectly, according to recent research by Child Car Seat Safety Limited. This statistic is particularly worrying because an incorrectly installed car seat won't offer the best protection in a crash.

Common problems include seatbelts not being in the route guides and Isofix points not being clicked into place. However, some parents are also using car seats that aren't the right match for their child's age, weight or height, which means the seat might not offer maximum protection.

Child car seat safety tests

In order to find the safest child car seats, we put each model through a series of intensive tests. First up are the crash tests, where we simulate both front and side-impact collisions. We conduct these at greater speeds than standard British safety tests to make them more realistic and also use a real car - the compulsory standard test just uses a mock-up of a back seat and only tests frontal collisions.

We also test car seats for ease of use, assessing how straightforward they are to fit and use on a day-to-day basis. We use a range of cars and test car seats in both Isofix and seat-belt modes.

The test results are combined to create a percentage score for each child car seat. Only the very best models become Which? Best Buy child car seats.
