Abstract
Abstract A seat construction comprising a frame and a spring assembly embedded in a body of foam plastic material and mounted on the frame. The spring assembly comprises a plurality of longitudinally extending wires at least one of which comprises a plastic cord, a plurality of transversely spaced wires having intermediate portions extending between the spaced wires and free ends extending beyond the longitudinally extending wires at an acute angle to the intermediate portion. The spring assembly further comprises a longitudinal wire along each edge connecting the free ends of said transversely spaced wires. A secondary spring assembly comprising longitudinal and transverse wires is provided along the sides of the spring assembly.
