ABSTRACT:
A step-stool for enabling a child to climb up to the top surface of a cabinet made of a top piece, a bottom piece and a middle step or platform piece adapted to slide out from between the top piece and the bottom piece to form a step. Two T-shaped spacers, one on each side, provide a channel for the middle platform piece to move outward and form the step. Screws, nails, or nuts and bolts act as fasteners to fit through the top piece, the two spacers and the bottom piece to hold them together, leave room for the middle slidable platform piece to be pulled out and to anchor the step-stool to a cabinet or other floor. The components of the step-stool of the invention may be marketed as a kit, put together to form an unanchored step-stool or anchored to a cabinet or other floor.
