Abstract: A knock-down article of furniture in the form of a box-like structure, having front, back, and first and second sides and at least one shelf member, is assembled by means of an arrangement of interconnecting tenon tongues and elongated mortise grooves in intersecting planes to cause the parts of the structure to interlock together to form a rigid structure without requiring any additional fasteners.
