Interchangeable arm (2) and armless (3) end frames include a common rear frame portion (16) joined to each respective front frame portion in butt wise fashion to give an integrated rather than tacked on appearance. The arm and armless end frames both have arcuately inturned rear portions (13, 46) and the armless has a similar arcuately inturned front portion (12) for joining to front (4) and rear (5) cross supports. In contrast, the upwardly extending front leg (43) of the arm frame includes an inwardly projecting bracket (48) for joining to the front cross support (4) and a sleeve (70) on the bracket compensates for the length of the inturned front portion of the armless frame. In a modification including a table top (76), since the front and rear cross supports are at different levels, a levelling bracket (85) having triangular shaped sides (86) is mounted between the front and rear cross supports to support the table top level.
