Abstract
A base drawer which has been modified to allow non-permanent attachment of an extender to increase the vertical dimension of the drawer. Additional extenders can be stacked one on top of the other, in order to increase the vertical dimension of the drawer to any height desired. In one embodiment, the base drawer has three receptacles along the top edge of its two side walls, and each extender has three matching locking prongs along the lower edge of its two side walls as well as three receptacles along the upper edge of each side wall which allow extenders to be stacked one on top of the other. When one or more extenders are attached to a base drawer (i.e., receptacles and prongs are interlocked), the receptacles and prongs on each side of the resulting stackable drawer assembly are in line.
