Abstract An article of furniture, such as a chair, has a basic horizontal frame structure, such as the seat frame, which is constituted by a pair of strip-like structural members that are formed to a desired common shape, such as arcuate, and arranged in a confronting, spaced apart, nested relation, such as concentric, and permanently joined in such relationship by bridging blocks or other spacers fixedly inserted in the gap between the members with the open spaces of the gap providing sockets for the fixed reception of mounting ends on the arm frames, back frame, and leg assembly. Such frame structure concept is applicable in the manufacture of top back rails, arms, rims and aprons and other such applications.
