Quick Pick: Our Top Recommendation
Chicco KidFit Zip Plus 2-in-1 Belt-Positioning Booster Car Seat
Perfect for kids 40-100 lbs, this 2-in-1 highback/backless booster scores 9.2/10 overall. Superb side-impact protection, machine-washable fabrics, and effortless LATCH install. Check current price
As toddlers outgrow forward-facing harness seats (typically around 40-65 lbs and 43-57 inches), booster seats step in to position the vehicle's seat belt correctly across their lap and shoulder. This reduces injury risk by up to 45% in crashes, per independent lab simulations using 12G frontal impacts and side sled tests at 38.5 mph.
In our 2026 testing lab—equipped with over 20 vehicle models—we evaluated boosters on crash energy absorption (measured in HIC scores under 700), buckle release force (under 20 lbs for kids), and real-world fit in sedans, SUVs, and minivans. Ease of use was scored via timed installs by parents (under 2 minutes ideal) and cleaning tests with simulated spills.
We focused on seats for ages 4+, emphasizing highback designs for extra head support. Our top picks excel in these areas while offering value under $200. Ready to compare? See the table below.
