The optimum sponge density and its combination of parameter ranges are determined. The results showed that the sofa cushions with different densities and various combination have a great influence on the comfort of the human body, but the comfort is the result of comprehensive factors, which is related to the density of the sponge, the sunken hardness, and the rebound index.
