A collapsible cart has pivotally interconnected backing and platform body members. A handle extends from the backing member and a clamp or other lock is provided to release the handle for movement to a variety of extended positions. The platform member is pivotally moveable toward and away from the backing member. The backing member and platform member include interlocking components to maintain the platform member in a fully extended or opened position, thus preventing its collapse against the backing member. The cart also includes a stop member to prevent the platform from opening beyond a desired position, particularly when placed under load.
