A cushion member 301 is a cushion member made of flexible resin or rubber and used for a passenger seat 300, and includes a porous structural body 1, and a top skin 330 serving as at least a surface FS on a seated person side among surfaces of the passenger seat and integrated with the porous structural body.

The purpose of the present invention is to provide a seat that makes it possible to easily connect the end of a surface cover when assembling the surface cover and to achieve a secure connection. To this end, a seat (1) is provided with inclined piles (70, 80) on the end of the surface cover (4) and at a location that faces the end of the surface cover (4) on a cushion member (2) that forms a seat section, the inclined pile (80) of the cushion member (2) is inclined in a direction that is the opposite of the direction in which a load resulting from a seated person occurs, and the inclined pile (70) of the end of the surface cover (4) is inclined in the direction in which the load resulting from a seated person occurs.

The present invention provides a seat which is unlikely to cause wrinkles or slack in a surface cover thereof, makes surface cover attachment and detachment simple, and is also capable of withstanding long-term use. To this end, a second fastening part 50 for attachably/detachably connecting a cushion material 2 and a surface cover 4 to one another is formed as a zipper in a seat 1.

A seat assembly that includes a main body portion having a seat portion and a back portion extending upwardly from the seat portion. The main body portion includes an inner layer and an outer layer.
