Abstract: A chair constructed of lightweight material such as fiberboard utilizes a one-piece, rectangular panel of foldable material to cover a seat support structure of perpendicularly disposed, interlocking support panels. The seat support structure defines a seat area that is covered by a portion of the cover panel defined by two parallel cuts therein that extend longitudinally of the panel for a predetermined distance and are spaced from each end of the cover panel. The cover panel is held in position around the seat support structure by tabs provided at each end for insertion into a transverse notch formed in the underside of the seat support structure.
