Abstract: A universal table A-frame that is constructed as a unitary structure for use in a booth seating system including a series of booths. The A-frame is a basic module for the booth seating system. The A-frame includes a pair of spaced apart frame rails arranged in a longitudinal parallel relationship and in the same horizontal plane by means of legs secured to the rails adjacent the ends of the rails. The A-frame includes a pair of elements that are individually secured to the inner edge of one of the rails and each extends upwardly towards the other rail. A horizontal frame element is secured in a cantilevered relationship to the free ends of the pair of elements to thereby complete the frame. The horizontal element is adapted to mount a table top. The legs of the A-frame may be offset for permitting the stacking of the A-frame in a nesting relationship. The frame rails are also provided with mounting plates for permitting the longitudinal adjustability of the frames.
