Harness Booster Car Seats

A harness booster car seat provides extended five-point harness security for your child with built-in transition to a belt-positioning booster seat as they grow. Your child can use the five-point harness until they meet the height and weight requirements – and are at least 4 years old – to transition to using the vehicle seat belt in booster mode. Browse our selection of the best harness booster car seats and find the perfect fit for your growing family.
