In order to operate the fastener 7 smoothly, the shape of the folding cushion 1 is preferably substantially oval and circular rather than rectangular.

As shown in FIGS. 2 and 3, protective material 2 constitutes the outer surface of folding cushion 1 . The protective material 2 is configured to be able to protect members arranged inside the protective material 2 such as the heat insulating material 3 . The protective material 2 is configured to cover the entire surface of the heat insulating material 3 facing the protective material 2 .

The protective material 2 has wear resistance. In other words, the protective material 2 is configured to be able to suppress wear or abrasion. The material of the protective material 2 is synthetic leather, for example. This synthetic leather is, for example, polyurethane (PU) leather. Polyurethane (PU) leather is a material in which polyurethane resin is applied to the surface of the fabric to make it look like natural leather. Moreover, the thickness of the protective material 2 is, for example, 1.2 mm. The protective material 2 preferably has heat insulating properties.

As shown in FIG. 2, the heat insulating material 3 is overlaid on the protective material 2 . The heat insulating material 3 has heat insulating properties. That is, the heat insulating material 3 is configured to suppress heat transfer between the protective material 2 and the first heat insulating sheet material 4 .
