Booster seats position your child so the vehicle's seat belt fits correctly — across the chest and lap, not the neck and abdomen. High-back boosters provide head support and side-impact protection. Backless boosters are more portable. Our testing evaluates belt fit, side-impact protection, and ease of use.

Frequently Asked Questions
When is my child ready for a booster seat?
When they've outgrown the maximum weight or height of their harnessed seat AND can sit properly in the booster for an entire trip without slouching.
High-back vs. backless booster — which is safer?
High-back boosters generally provide better side-impact protection and head support. Backless boosters are fine in vehicles with high seat backs, but high-back is the safer default choice.
