This car seat 4 in 1, the Safety 1st EverSlim 4-in-1 Convertible Car Seat, keeps your child secure and comfortable through every age and stage, with four modes of use—rear-facing (5–40 lbs., 19"–40"), forward-facing (30–65 lbs., 34.4"–49"), belt-positioning booster, and backless booster seat modes (40–100 lbs., 43.4"–52").

The seat’s ultra-slim design—just 17.3" across without the cup holders—fits three across most vehicle back seats without sacrificing comfort, making it an ideal slim carseat for families who travel together. The SecureTech red-to-green indicator on the chest clip allows you to see when the clip is securely fastened to the seat belt.

As a grow with me car seat, EverSlim features a 5-position-recline base, a one-hand 10-position adjustable headrest, and an easy-to-convert backless booster, so parents wanting peace of mind can restrain their child from infancy through age 10. Machine-washable, dryable fabric helps maintain a fresh seat that is always ready for use in your vehicle.

Actual fit may vary. Not all children will comfortably fit in the seat for the full weight and height ranges listed.
