ABSTRACT:
The specification discloses modular seating in which interchangeable arm and armless end frames include a common rear frame portion 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 and the armless has a similar arcuately inturned front portion for joining to front and rear cross supports. In contrast, the upwardly extending front leg of the arm frame includes an inwardly projecting bracket for joining to the front cross support and a sleeve on the bracket compensates for the length of the inturned front portion of the armless frame. Since the front and rear cross supports are at different levels, a leveling bracket or apron having triangular shaped sides is mounted between the front and rear cross supports to levelly support a table top thereon.
