Abstract
A seat which can obtain a favorable sitting feeling using a fibrous structure is provided. A seat 1 is provided with a cushion body 11 comprising fibrous structures 4a to 4d and a seat frame 15 supporting the cushion body 11, in which the fibrous structures 4a to 4d are formed by stacking a web 2 so that the web 2 extends along a thickness direction T of the fibrous structures, the cushion body 11 is formed so that the thickness direction T of the fibrous structure 4a is along a load direction applied on the cushion body 11 at sitting, and a stacking direction of the web 2 constituting the fibrous structure 4a is along a widthwise direction W of the cushion body 11. Since the web 2 easily falls down along the widthwise direction W of the cushion body due to a load of a seat occupant, the cushion body as a whole is in a shape curved along the widthwise direction W around a region where the load is applied, and the body of the seat occupant is supported as if being surrounded from both sides in the widthwise direction W. Thus, the seat occupant can obtain a soft touch feeling.
