ABSTRACT:
An improved chair frame and method of fabrication is disclosed in which an extremely rigid uniframe chair construction can be assembled from a variety of components fabricated out of sheets of plywood. The chair frame includes a base frame assembly having a one-piece D-shaped base plate upon which one or more side plates may be stacked and secured to achieve the desired base frame assembly thickness. The chair frame also includes a back frame assembly having a pair of back posts and a pair of front posts secured to the base frame assembly. A top rail interconnects the rear posts and a pair of arm rails interconnect the front posts and the rear posts. The various components of the chair frame are interconnected with mechanical joints to further enhance the strength and structural rigidity of the chair frame.
