Best Booster Seats

When your child outgrows the forward-facing harness on their car seat — typically around 40 to 65 pounds — a booster seat is the next step. Boosters lift your child so the vehicle's lap-and-shoulder belt fits correctly across the chest and hips instead of riding up over the neck and abdomen. Here are the best high-back and backless boosters based on independent crash testing and ease of use.

The Five-Step Seat Belt Fit Test

Your child is ready to ride without a booster when they can: (1) sit all the way back against the vehicle seat, (2) have knees bend naturally at the edge of the seat, (3) the lap belt sits low across the hips, (4) the shoulder belt crosses the center of the chest, and (5) they can maintain this position for the entire ride. Most children pass this test between ages 8 and 12.
