A cart for transporting materials along a floor having a base positioned parallel to the floor. Positioned above the base is a rectangular cover having a first side edge, a second side edge and a back edge defining three sides of a rectangle. A first side support, a second side support and a back support each extend from the base to the cover. Four vertical supports extend from the base to contact the cover at four points substantially aligned with a first diagonal of the rectangle.
