PROBLEM TO BE SOLVED: To reduce a pressure to the femur and improve the body pressure dispersing property. SOLUTION: This seat structure is so formed that a support layer 40 disposed in the lower side of a front-side cushion layer 20 which is composed of a three-dimensional knitting or the like tensed to a cushion frame 10 at a low tensile force, is provided with a first planar support member 41 tensed in the front/rear direction of the cushion frame 10, and a second planar support member 42 superposed on the first planar support member 41 and tensioned in a position corresponding to at least the front edge portion 20a of the front-side cushion layer 20 along the width direction of the cushion frame 10. This constitution can improve the supporting property of the front-side cushion layer 20 at least in the front edge portion 20a to reduce the abutment of the front frame 13 and reduce the pressure applied to the femur back side in operating a pedal or the like.
