Abstract
Abstract An article of furniture comprising a plurality of rigid tubes arranged vertically in side-by-side relation, and fastened together. A load-bearing member, such as a flat board, rests upon the upper ends of at least some of the tubes. The board may carry inserts which frictionally fit into the upper ends of the tubes to help hold the tubes together in a unitary assembly. The article may include relatively short tubes for supporting the board, and relatively long tubes defining a chair back and chair arms.
