Children are ready to move to a booster seat once they have exceeded the maximum weight or height limit of their harnessed car seat — typically around 3.5 to 4 years old. A high-back booster is always recommended over a backless booster for younger children, as it provides superior head and side-impact protection. In the UK, children must use an appropriate car seat until they reach 135cm in height or their 12th birthday. UK Legal Compliance & Safety Standards All booster seats in our collection meet either the R44 or the newer R129 (i-Size) safety regulations, ensuring full UK legal compliance.
