Abstract: A base for supporting the weight of a user, tools and a ladder is described. The base can be formed of a plurality of rigid plates, each plate having a top and a bottom side. The plates can be hingedly connected to fold together along a longitudinal axis with the bottom sides of the respective plates being positioned adjacent to each other. The base can include a plurality of wheels positioned around the bottom side and the periphery of each plate. The wheels can be positioned to oppose one another and the opposed wheels being positioned off center from each other when the plates are folded such that the wheels do not interfere with each other, the base when folded is adapted to be stored with the longitudinal axis in a substantially vertical direction.
