This is the patented hand cart that “walks” up and down stairs and doubles as a portable folding chair. Unlike a two-wheeled handcart which can be unwieldy on stairs, this six-wheeled cart maintains contact with the horizontal tread and the vertical riser on each step for effortless hauling. It easily transports loads up to 75 lbs. on its flat base or in the attachable black nylon bag. Simply folding down the integrated padded seat converts the cart into a chair that supports up to 300 lbs. With lightweight aluminum frame, shielded ball bearings, and padded, telescoping handle. Folds to 21 1/2" H x 24" W x 4 1/2" D for compact storage. Unfolded: 43" H x 25" W x 18" D. (8 lbs.)
