Claims

[Scope of utility model registration request]

In a mattress device in which a spring unit is formed by connecting a large number of coil springs in a flat plate shape, fillings are attached to the upper and lower surfaces of this spring unit, and these are covered with an exterior fabric, one of the above fillings is , an airtight sheet is formed into a bag shape, and inside the bag body formed to freely supply and discharge air, at least a first,
It is divided into a second and third chamber, and a foamed elastic body is housed in each room, so that the hardness of the foamed elastic body housed in the second room is different from that of the foamed elastic body housed in the other rooms. What is claimed is: 1. A pine stress device, characterized in that it is formed so that the air inside the bag can be discharged to cause the bag to contract and the foamed elastic body to be compressed to change its hardness.
