The seat is designed with machine washable ComfortTouch seat padding, deep head supports, and pivoting armrests that provide comfort to the child. The Evenflo Big Kid Deluxe has a one-hand pull handle that easily adjusts the height and depth of the seat into 6 positions to accomodate the child as they grow. It also features built-in activity lights and retractable side compartments to store drinks, snacks, and activities. The carseat has been tested to meet or exceed all applicable US safety standards. The Evenflo Big Kid Deluxe differs from the less advanced Big Kid LX since it includes activity lights and ComfortTouch padding on the seat and armrests which the LX model lacks.
