The Safety 1st Summit Deluxe High Back Booster Car Seat features ease of use that any parent can appreciate. The 3-position QuickFit? headrest adjusts without the need for rethreading and the 5-point harness can be adjusted right from the front. The pivoting armrests make it easy for your child to get in and out of the car seat, while the 3-position recline lets you give them the most comfortable position for the ride. With a convenient slide-out cup holder built right into the side of the car seat, your child will have an easy place to store a drink while on the road.
