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.

Abstract: A chair has a removable back portion and a base portion connectable by unique female/male tapered connectors attached to the base portion and back portion with the base portion being shaped and dimensioned to be received in a carton having a tapered rear portion provided by diagonal vertical panels on opposite sides of a rear vertical wall panel with the base carton being shaped and dimensioned so that the sum of its girth and height do not total more than 130 inches so that the carton can be shipped by a parcel service shipping company such as UPS rather than by regular freight with the back being separately shipped in a separate package so that total shipping charges are much less than regular freight charges.
