ABSTRACT:
A furniture construction, such as a chair, table or foot stool, may be made by cutting a flat circular member into a plurality of panels along chordal lines thereof. The chair, for example, may be formed out of four identical panels, as defined by first and second perpendicular pairs of parallel chordal cut lines. In assembling the chair, seat and back panels are clamped between a pair of laterally spaced side panels by a plurality of tie rods and the back panel is adjustably mounted on the seat panel. In the preferred embodiment of this invention, the edges of the panels are each covered by cushioned edging means comprising a plurality of first fibrous ropes extending the full length of such edge and a second continuous fibrous rope extending sequentially through a plurality of apertures spaced along and inwardly of the edge in spiralled and wrapped relationship over the first ropes to bind them against the panel.
