Kids ride longer with the Cosco Apt 50 Convertible Car Seat - all the way to 50 pounds. The Apt keeps them safer during every stage, with Side Impact Protection and 4 harness heights for the best fit as they grow. They'll love the comfortable ride and you'll love the machine washable pad that makes messes easy to clean. No more worries about dropped juice or those crazy cracker crumbs. Just take off the pad and toss it into the machine for a real neat seat you can't get with spot cleaning. Two integrated cup holders make sure your copilot has plenty of room for drinks or a snack during the ride.
