ABSTRACT A seat spring assembly for an upholstered furniture seat, which comprises a seat frame including a front rail and a back rail, a plurality of sinuous spring bands connected to the front and back rails and extending therebetween in substantially parallel relationship with the plurality of bands including an outermost band, and a normally straight, stiff wire span member extending longitudinally of the outermost band and substantially coextensive therewith between the front and back rails. One end of the wire span member is fastened to one of the bands and one of the rails at a point adjacent the one rail so that the one end of the wire member cannot move long- itudinally relative to the fastening point, and the opposite end of the wire span member is fastened to one of the bands and the other of the rails at a point adjacent the other rail. A key means is disposed between the wire span member and the outermost band and fastened rigidly to both, with the span member and key means being effective to permit a controlled, limited deflection of the outer- most band under normal load.
