Frequently asked questions
- Are high-back boosters better than backless ones?
- High-back boosters guide the belt across the shoulder and add side-impact protection, which backless cushions lack. They are generally recommended for younger or shorter children.
- When can a child use a booster seat in the UK?
- Children can use a high-back booster once they reach 100cm tall, or 125cm and 22kg for R44 booster cushions, until they are 135cm or 12 years old.
- Does a booster need ISOFIX?
- No. Boosters use the adult seat belt to restrain the child, though many include ISOFIX connectors that simply hold the empty seat in place.
