The raising member can be easily removed from the member, and the frame member and the raising member can be more easily separated than when the entire frame member is embedded.

  Moreover, it is preferable that the said raising member is equipped with the frame member exposure part formed so that a frame member might be exposed from a raising member in the state attached to the frame member.

  According to such a configuration, since the raising member includes the frame member exposing portion, the frame member is exposed on the surface of the raising member, and therefore, the raising member can be easily removed from the frame member as compared with the case where the entire frame member is embedded. It can be removed and can be easily separated.

  Further, the surface cover includes connecting means configured to be detachable from the frame member, and is configured to fix the cushion material to the frame member in a state where the connecting means is connected to the frame member. Preferably it is.

  According to such a configuration, the surface cover is configured to fix the cushion material to the frame member in a state where the connecting means is connected to the frame member, so that the connecting means can be removed from the frame member. Thus, the coupling between the cushion member and the frame member can be easily released, and the separation can be easily performed.

  Moreover, it is preferable that the said raising member is provided with the insertion part comprised so that it could be fitted in a cushion material in the state laminated | stacked on the cushion material.

  According to this configuration, the cushioning member and the raising member can be easily fixed by the fitting portion because the raising member includes the fitting portion. Moreover, since the cushion material and the raising member are fixed only by the fitting portion, the cushion material and the raising member can be easily separated.

  Moreover, it is preferable that the said raising member consists of a foaming molding whose compressive strength is higher than a cushion material.

  According to such a configuration, the raised member is formed from a foamed molded article having a higher compressive strength than the cushion material, so that the cushion material can be stably supported even when the cushion material is deformed by a load. And the height of the cushion material 2 can be maintained.
