<p>PROBLEM TO BE SOLVED: To provide a cushion body of a two-layer structure which is rich in cushioning property while a person is seated or lying supine, is capable of achieving weight saving, and is excellent in recyclability.SOLUTION: A cushion body of a two-layer structure includes a first cushion body composed of a support body made of synthetic resin foam whose deflection in bending measured according to a method described in JIS K7221-2:2006 is 20 mm or more, and whose load at the time of 20 mm deflection is 2-100 N and a leg body for supporting the support body, in which the support body and the leg body form a space part in which the support body can be bent and deformed, and which receives a load from a seated or lying person, and a second cushion body having elasticity of a 25% compressive hardness of 5-200 N/φ100 mm installed on the seated or lying person side of the support body which covers at least the surface range on the seated or lying person side of the support body, and receives a load from the seated or lying person.</p> |
