PURPOSE:To generate the superior air ventilation for a user and prevent the generation of bed disease by reducing the musty state by dispersing perspiration by using a carpet in which a number of thin plate-shaped small pieces are arranged length wise and crosswise and supported onto wires laid onto a frame body, by the placing on a body supporting device which possesses cushion function. CONSTITUTION:Supporting wires 3 are laid in the lengthwise and crosswise through each coil spring 2, onto a frame body 1, and a number of flat thin plate-shaped small pieces 4 are arranged lengthwise and crosswise and supported onto the supporting wire 3, and a pulling means 5 for the supporting wire 3 is constituted. The carpet is used by the placing onto a body supporting device 7 such as urethane mat and air mat. The body weight of a laid person is supported by the body supporting device 7 through the carpet. The carpet is raised and lowered with the body supporting device according to the body weight, and the body is supported by the thin plate-shaped small pieces 4. Since the supporting wire 3 is positioned between the thin plate-shaped small pieces, the air ventilation through the obverse and reverse surfaces is improved. |
