Abstract
A tubular frame having a plurality of tubular members and a backing member. The tubular members are held together by round corner members. The corner members have hollow tubular insertion members or legs at one end and "X" or "cross-shaped" insertion members or legs at the other end in order to mate with adjacent tubular frame members. The two insertion members are adapted to be joined to a tubular member in only certain orientations which assists in manufacturing and assembly. The tubular frame members also have elongated channels on one side for mating with the backing member.
