One transformable creeper includes three portions. The first portion has a frame, four wheels operatively coupled to the frame such that a lower edge of the frame is maintained above a lowermost point of the four wheels by no more than about two thirds the diameter of the four wheels, and a first support surface operatively coupled to the frame. The second portion has a second frame rotatably coupled to the frame and a second support surface. A lock maintains the second frame at three angles relative to the frame (generally 180°; between about 90° and 180°; and between 0° and 90°). The third portion has a third frame rotatably coupled to the second frame, two wheels, and a third support surface. A lock respectively maintains the third frame at two angles relative to the second frame (generally 180°, and between 0° and 90°). |
