The cushion material used as the seat cushion 20 does not need to be particularly limited, and examples thereof include molded ethyl urethane.

When assembling the sofa 100, the shape of the main cushion 21 is such that it thickens from the end on the side of the backrest 40 toward the end on the opposite side and swells. The sub-pad 22 is in the shape of the recess 12 accommodated in the base 10, but preferably, the sub-pad 22 is smaller than the recess 12 at least as much as the size of the position-adjusting adjustment rod 80, so that The size of the rod 80 is adjusted to adjust the position in the recess 12 of the sub-pad 22.

The main pad 21 and the sub-pad 22 may also be formed by cushion materials with different hardness. For example, the sub-pad 22 used to prevent the position of the seat cushion 20 from shifting is a hard cushioning material; the main cushion 21 of the part where the user rides is a soft cushioning material. When using molded urethane as a cushioning material, a high-density molded urethane can be used as the sub-pad 22, and a low-density molded urethane can be used As the main pad 21. In addition, the seat cushion 20 may have a fragment urethane chip on the side where the main cushion 21 becomes the seating surface. In addition, an independent cylinder spring may also be used as a cushioning material, for example, molded urethane is used as the main pad 21, and an independent cylinder spring is used as the sub-pad 22. When an independent cylinder spring is used as the sub-pad 22, the concave portion 12 is a receiving portion of the independent cylinder spring. In this way, by constructing the seat cushion 20 with a plurality of cushioning materials of different hardnesses, a sofa excellent in riding comfort can be provided.
