(Prior Art) Conventionally, cushioning properties have been adjusted by adjusting the tension of S springs stretched on the left and right sides of the frame, or as disclosed in Japanese Utility Model Application Publication No. 139304/1983, Some have a seat plate placed inside that moves up and down using a spring. All of these adjust the cushioning properties (deflection) by adjusting the tension of the spring, but since the spring constant of the spring is constant, the adjustment range is narrow.
Moreover, there is a risk that the market will bottom out.

(Structure) In the present invention, an auxiliary frame is rotatably supported vertically around the front end of the frame, and the rear part is suspended from the frame by a spring with a spring constant different from that of the spring. The auxiliary frame is urged upward and the tension of this spring is adjusted by rotating a cam. Therefore, since the auxiliary frame is suspended by at least two springs having different spring constants, the adjustment range of cushioning properties is wider than that of conventional products, and the seated person can obtain what he or she desires.
