Abstract:
This mattress, upon which a user may lie, comprises a mattress cushion that can be divided in the length direction into a plurality of cushion bodies and a mattress cover capable of accommodating the mattress cushion. Each of the plurality of cushion bodies is formed using a three-dimensional filament bonded material that is made of a resin and has, at both end portions in the thickness direction, a smooth surface layer that has a higher filament density than the center portion in the thickness direction. The three-dimensional filament bonded material has a thickness of 10-25 cm, a filament diameter of 0.5-2 mm, and a bulk density of 30-150 kg/cm3. The mattress cover has, on a circumferential surface portion, a stretch-preventing member for preventing the mattress cover from stretching in the length direction.
