ABSTRACT:
A self-contained and self-supporting wire suspension system is provided for use within a seat construction. The system includes either one bolster wire or a pair of parallel bolster wires, a set of parallel stringer wires wrapped around the bolster wire(s), and a pair of parallel border wires secured to the free ends of the stringer wires. The system further includes a top or seat supporting portion defined by the segments of the stringer wires which extend between the bolster wires or between one border wire and a bolster wire. The top portion is resiliently supported by at least one leg portion defined by stringer wire segments extending between bolster and border wires. The border wires are secured to a support surface or a wire frame. Lateral support members extend diagonally between the leg portions to provide stability. The stringer wires may be embedded within a plastic foam seat cushion.
