A metal base of a type particularly suitable for seating as a swivel chair, desk chair, or secretarial chair; equally suitable as a table base for supporting both small and large size table tops from a center column or post; and also suitable for supporting the ends and corners of tables and seating for rectangular tables and desks and for modular or tandem seating. The suitability of the same base for all of these applications gives a unified appearance of products which is a very desirable feature for furniture of this type. The base includes a plurality of horizontally disposed leg elements, each formed of a strip of metal bent upon itself to form an outer semi-circular end and a pair of parallel members, the inner ends of which are mutually interconnected at a centrally positioned location which supports a vertically oriented hollow socket element. The fabrication of each of the disclosed embodiments requires no casting operation, and several of the embodiments permit assembly without resort to welding operations.
