What Is a Booster Seat?

A booster seat helps position your vehicle’s seat belt correctly once your child has outgrown their forward-facing harnessed car seat (typically around 40 lbs and at least 4 years old).

Boosters raise your child so the lap belt fits low across the hips and the shoulder belt sits properly across the chest — both critical for safety.

Booster seats come in high-back, backless, and 2-in-1 designs, each offering different benefits depending on your child’s size, comfort needs, and vehicle setup.
