It’s important to note that you shouldn’t fit a rear facing seat in the front when there is an airbag active. All babies that are less than 15 months old should use a rear facing seat and once their necks are stronger, they can begin to use a front facing seat. For further child seat laws in the UK, we advise that you read the RAC guide.

All of our recommendations are suitable for a range of budgets and newborns up to the age of 12 years old. To avoid disappointment, we advise that you analyse the dimensions of the seat and buy from a reputable brand in the UK.
