*Some of our seats are designed for a more specific weight/height group (eg Birth to 13kg/87cm). Our All in All range is an “All Stages” seat and is designed to cover a much wider weight/height range (Birth to 36kgs/150cm). Therefore, the All in All Range will appear in all of the categories below.
There are the two separate, current car seat standards that you need to be aware of to meet car seat legislation across Europe: R44 and R129/i-Size. Children up to the age of 12 years old or under a set height (135cm) should always travel in a car seat that meets one of these approved standards.
As ECE R44 is an older standard, it is planned to be gradually phased out. The reason for the gradual change is that seats made to the newer R129/ i-size standard are usually significantly more expensive. PLEASE NOTE: At present there is no clear date for phase out of ECE R44 seats in mainland UK and be assured they are perfectly safe to buy and use.
About ECE R44: This standard recommends that your child travels rearward-facing for at least 9 months but with R129 it is mandatory that your child travels rearward-facing for longer – 15 months.
Seats that have specific features that are designed to be compatible with i-Size cars, to avoid misfitting.
