The Best Car Seat from 4 Years in 2021

Updated 10-03-2021 – Lucy Walters

According to GOV.UK, children must use a child car seat until they are 135 centimeters or 12 years old, whichever comes first. So, if you have a young girl/boy at home who has outgrown their car seat, it is necessary that you find the best car seat that can be used from 4 years. When choosing from the many available options, you can either go with a height-based seat or weight-based seat.

Though your kid had been traveling in a child car seat for a long time now, the one big change they will realize when transitioning to their big girl/boy car seat is that there will be no 5-point harness; instead, they will now be using an adult car seat belt to stay secure. Given below is our list of the best car seats from 4 years in the UK:
