Abstract:
Provided is a pillow cushion with which it is less likely for a repulsive force to concentrated on a user's head in an area close to the highest point of the crown, and with which it is easier to stabilize the user's head. The pillow cushion is formed from multiple filaments comprising a thermoplastic resin or a thermoplastic elastomer, the filaments being tangled three dimensionally with one another, where the points of contact between the filaments are fuse-bonded to form a three-dimensional filament integrated body. The area that supports the crown of the user's head has a higher filament density at both edges in the directions toward right and left shoulders than at the center.
