A fastening member according to the invention includes right and left sewn areas which are sewn to one member out of a cushion member and a cover material, a hook-and-loop fastener area which is disposed between the right and left sewn areas and which has a plurality of female engagement elements formed on one face thereof, and a connection area which connects between the hook-and-loop fastener area and the respective sewn areas. Here, the connection area is configured to have a lower yarn density than that of the sewn areas and allows the hook-and-loop fastener area to be displaced relatively to the sewn areas. According to the fastening member of the invention, since the fastened cover material can be easily displaced against the cushion member, wrinkling occurrence at the cover material can be prevented when the cover material is assembled to the cushion member.
