Abstract: A chair base includes a leg assembly having a plurality of radially extending legs, and a leg cover adapted to cover the legs. The tubular legs have a top surface divided by a centerline and have apertures offset from the centerline. The leg covers are adapted to cover the legs, and the leg covers include downwardly extending off-centered bosses for engaging the apertures. Each of the tubular legs has an end with aligned vertical holes therein. A sleeve-like pintle receiver is located in the aligned vertical holes and flared at its top and bottom to hold the pintle receiver in the tubular legs. The leg assembly includes a tubular center hub. The plurality of radially extending tubular legs each have a top wall, a bottom wall, and opposing sidewalls, the top and bottom walls each having an arcuately shaped end engaging the center hub. A pair of ring welds extends continuously circumferentially around the center hub for welding the arcuately shaped ends of the top and bottom walls to the center hub.
