Abstract
Chair frames are formed from identical tubular frame components having tubular studs projecting laterally therefrom in a mirror image arrangement and crimped to telescope into the ends of tubular stretcher members. The crimped portions of the studs provide two abutting walls increasing the anchoring capacity for stretcher carried screw fasteners which are threaded therein to lock the stretchers to the studs. The ends of the stretchers abut the frame to cover any weld beads joining the studs to the frames. All of the tubular components are electroplated.
