Back booster car seats help older children sit at the right height for a vehicle seat belt. A proper booster can position the lap belt across the upper thighs and the shoulder belt across the middle of the chest and shoulder. High-back boosters can also provide head and side support, while some models convert into backless boosters as a child grows.
The right booster depends on your child’s height, weight, age, and the vehicle you use. Check the manufacturer’s limits before buying because booster seats have different height and weight ranges. High-back models can work well for younger booster riders, while backless models can offer a lighter option for older children who already have good support from the vehicle seat. Models such as the Chicco KidFit, Britax Skyline, Graco TurboBooster, and UPPAbaby Alta V2 offer different combinations of high-back and backless use.
This guide covers six of the best back booster car seats for different children, vehicles, and budgets. We considered belt positioning, height and weight limits, comfort, head support, adjustability, portability, LATCH features, and overall value. These picks can help you find a booster that gives your growing child a more comfortable and properly positioned ride.
