A cushion body including a continuous coil-spring assembly which comprises coil portions and linear connection portions, and a method for forming such cushion body. The continuous coil-spring assembly is pressingly inserted into a jig, and both jig and coil-spring assembly are subject to a low-temperature annealing treatment. Thus-treated coil-spring is then foamed with a urethane base material in a mold, so as to produce such sort of cushion body. |
