The best isofix car seats: keep your little one safe on the road

The best isofix car seats

An isofix car seat is one of the safest ways to transport your baby from A to B. They connect to an integrated system that exists in most cars and they have been designed to perform highly in the event of crash, absorbing shock and preventing the seat from dislodging.  

Before you buy an isofix car seat, you need to make sure that your car features the correct fixtures and fittings. Which? have put together a detailed guide about isofix car seats, so make sure you familiarise yourself with what you need to look out for before you buy. 

With regards to the isofix car seat itself, you need to ensure that you purchase a car seat within the right group. 0 and 0+ seats are suitable for birth upwards, with the 0+ lasting right up to 15 months. Once your baby has surpassed the weight boundaries of a group, you’ll need to upgrade the seat to the next group up, and if you purchase an i-Size seat, like the Maxi Cosi Pebble Plus, you’ll have to consider their height, too.
