PURPOSE:To reduce a time at which a seat is in contact with the leg part of a seated person and prevent sweating by forming the front side cushion of said seat into a double structure of upper and lower parts and making the resilient elasticity of the lower cushion member smaller than that of the upper cushion member. CONSTITUTION:The structure of the front side of a seat 1 is formed into a double structure by providing a separate cushion member 7 on the lower part of a cushion member 5. The front face and top face of the lower cushion member 7 are bonded to the upper cushion member 5 and its bottom face is fixed to the top face of the bottom board 3 of a skeleton frame 2. And, the resilient elasticity of the lower cushion member 7 is made smaller than that of the upper cushion member 5. Accordingly, the time at which the seat 1 is in contact with the back side of the leg part of a seated person can be reduced by the time until the lower cushion member 6 is restored to its original form, improving a ventilating property and removing uncomfortableness due to sweating.
