Abstract: A spring edge for a furniture deck, the deck consisting of a wire fabric deck sheet resiliently supported over a rigid frame, the spring edge consisting of a series of generally V-shaped sinuous spring elements distributed along the forward edge of the frame, opening forwardly, the lower legs of the elements being fixedly related at their forward ends to the frame and deck, and the apices of the elements being connected to the deck for forward and rearward sliding movement, the upper legs of the spring elements being inclined upwardly and forwardly and supporting a transversely extending horizontal border wire at their upper ends.

Abstract: A spring assembly for a seat having a rigid frame including front and rear rails, comprising a flexible deck sheet connected at its rearward edge to said rear frame rail, with its forward edge spaced rearwardly from the front frame rail, a series of angled levers spaced across the forward edge of the deck sheet and vertically pivoted thereon, the longer upper legs of the levers being inclined upwardly to be spaced at their upper ends above the front frame rail to form a bolster support, links connecting the free ends of the shorter lower legs of the levers to the front frame rail, and springs applying elastic tension to the deck sheet, lower level legs and links between the front and rear frame rails.
