The present invention relates to a mattress for a hospital bed (1) manufactured by filling a rectangular parallelepiped case (1a) made of synthetic leather of a certain thickness and having the width of 1 m, the length of 2 m and the thickness of 8 cm with sponge (1b). The mattress for a hospital bed is configured such that through holes having the diameter of 2-3 cm are vertically formed in multiple rows on selected portions such as a portion (a) that is in contact with a shoulder area, a portion (b) that is in contact with a back area, and a portion (c) that is in contact with hips when a patient is lying on the mattress. A supporting pipe (20) comprises: a synthetic resin pipe (20a) with an outer diameter and the length corresponding to an inner diameter and the length of the through holes and having excellent elasticity； and flanges (20b, 20c) formed on upper and lower ends, expandable circumferentially from the upper and lower ends of the pipe so as to be attached to a surface of synthetic leather, through which upper and lower end portions of the through holes are exposed, and having an outer diameter of 4-6 cm wherein the supporting pipe (20) is inserted into each through hole so that a vent hole (2) is formed at the center of the supporting pipe (20). An outer surface of the mattress for a hospital bed is covered with a natural fiber outer skin (3) which is antibacterial and woven loosely to obtain favorable ventilation. As the outer surface of the mattress for a hospital bed is covered with the outer skin that is antibacterial and formed with ventilating fiber mesh, the surface of the mattress can be kept hygienically, thereby having a positive effect on the health of a patient in a relative long time.COPYRIGHT KIPO 2018본 발명은 일정두께의 합성피혁으로 제조되어 가로 1m, 세로 2m, 두께 8cm 되게 제조한 직육면체의 케이스(1a)속에 스펀지(1b)를 충진하여 제조되는 병원 환자용 매트(1)에 있어서,환자가 매트 위에 누웠을 때 어깨가 닿는 부위(가)와 등이 닿는 부위(나)와 엉덩이가 닿는 부위(다)를 선택하여 직경 2~3cm 되는 통기구멍을 상하로 관통되게 다열로 형성하고, 각 통기구멍에 통기구멍의 내경과 길이에 대응하는 외경과 길이
