The present invention relates to a pedestal base for a chair that is capable of supporting safely up to a 500 pound person in normal, continuous commercial or industrial use. The present pedestal base has six legs, a substantially cylindrical hub, and six caster attachment means with a caster or glide in each caster attachment means. Each leg is separated from its neighboring legs by about 60 degrees. The base elements are selected within particular dimensions and are made from materials having minimum selected yield strengths. In particular, the pedestal chair base as a whole can pass BIFMA test No. 8 with a 5000 lb load being applied, instead of a 2500 lb load, and can pass BIFMA tests No. 9 and No. 18, each with a 500 lb load being used instead of a 300 lb load.
