ABSTRACT:
A self-leveling table has a rectangular top bolted to a unitized base. The base has a horizontal rectangular frame which supports the top fabricated from four welded angle irons. The frame is supported by two pairs of crossed legs, welded at the cross, each of which terminate in a foot. The feet are heavy sheet metal bent slightly so as to touch the floor only at the ends. The table top is fitted with latching devices at each end of the top for attachment of a table extension or another table.
