Frequently asked questions
- What are the UK car seat rules?
- Children must use an appropriate car seat until they reach 135cm tall or turn 12, whichever comes first. The seat must be correctly fitted and approved to the relevant standard.
- What does i-Size mean?
- i-Size is a regulation based on a child's height rather than weight. It promotes longer rearward-facing travel and is designed to improve protection, particularly in side impacts.
- Is an Isofix base safer than belt fitting?
- Isofix clips to fixed anchor points, reducing the chance of an incorrect installation. A belt-fitted seat can be equally safe when fitted correctly, but is easier to fit wrongly.
