Abstract: A generally rectangular modular table unit is disclosed which is adapted to being stacked to create larger furniture assemblies but is also capable of being assembled so as to stand alone. Each table unit includes four legs (20, 22), a pair of side bars (30, 32) extending along the sides of the unit, and a planar member (44) to form the top of the unit. A pair of top and bottom cross bars (24, 26) extend across the ends of each of the units. The cross bars (24, 26) have rabbetted recesses (28) formed at each of their ends and each is fastenable to the adjacent legs (20, 22) in one of two configurations, one configuration being adapted for interlocking with adjacent table units in a stack while the other configuration is adapted for table units which are intended to stand alone.
