A cushion body, which can secure both soft touch feeling and durability, a seat having the same, and a manufacturing method thereof are provided. A cushion body 11 is constituted by stacking a sheet-like fibrous structure 4a with a low density in which webs 2 are stacked such that their extending direction conforms with a thickness direction T of the cushion body and a sheet-like fibrous structure 4b with a high density whose flexing degree to load in the thickness direction T is smaller than that of the sheet-like fibrous structure 4a with a low density, where the sheet-like fibrous structure 4a with a low density is disposed nearer a sitting surface 10a than the sheet-like fibrous structure 4b with a high density. Since the sheet-like fibrous structure 4a with a low density on the side of the sitting surface 10a receives load from the outside of the cushion body 11 due to sitting and flexes largely, it provides soft touch feeling to an sitting occupant. On the other hand, since the sheet-like fibrous structure 4b with a high density is small in flexing amount and it has hardness to some extent, it is hard to fatigue in a load direction, so that durability can be secured. |
