Abstract: A cushion member is provided which can stabilize a head position while sinking a head moderately. The cushion member is a cushion member for a pillow which is formed using a filament three-dimensional bonded member obtained by three-dimensionally fusing filaments formed of a thermoplastic resin, in a width direction, repulsive forces in regions on the sides of both end portions are higher than a repulsive force in the region of a center portion and in a depth direction, repulsive forces in regions on the sides of both end portions are higher than a repulsive force in the region of a center portion.

Abstract: A bedding includes: a cushion layer which is formed with a filament three-dimensional bonded member and which is breathable; a breathable water-repellent layer which is provided on the upper side of the cushion layer and which is breathable and water-repellent; and a breathable water-retentive layer which is provided on the upper side of the breathable water-repellent layer and which is water-retentive and is breathable during water retention.

Abstract: In a device for manufacturing a filament three-dimensional bonded member includes: a molten filament supply device which supplies a plurality of molten filaments; a three-dimensional structure formation device which receives and then cools and solidifies the molten filaments so as to form a filament three-dimensional bonded member; and a controller which controls the molten filament supply device and the three-dimensional structure formation device, a hardness index measurement device is provided which measures the hardness index of the filament three-dimensional bonded member that is brought into a cooled state by the three-dimensional structure formation device, and the controller uses the information of the measurement of the hardness index measurement device that is fed back and thereby performs feedback control on at least one of the molten filament supply device and the three-dimensional structure formation device so as to reduce a variation in the hardness of the formed filament three-dimensional bonde
