A chair base is constructed by stamping straps (16) from low carbon sheet stock, securing pairs of straps to a central hub (10) in parallel relation to one another to radiate outwardly from the central hub, and coating the straps and hub with a polyvinyl chloride coating (50). A caster socket block (20) may be secured between the two straps of each pair at an outer end (18) thereof. The central hub (10) and the caster sockets (20) may be covered by plastic shells (34).
