PROBLEM TO BE SOLVED: To provide a cell for a mattress having a new structure which can prevent bottom hitting and which can achieve stable supply/exhaust of a fluid with a simple structure, and a mattress using the same.SOLUTION: An elastic body 30 is accommodated in a fluid chamber 26, and an upper region 32 formed above the elastic body 30 can set the change of volume by adjusting a fluid amount inside the fluid chamber 26. On an outer peripheral edge part of a bottom wall of a bag-like body 12, a guide support part 20 is formed which gradually tilts upward toward the outer peripheral side, and the elastic body 30 is supported by a lower surface outer peripheral edge coming into contact with the guide support part 20. A lower region 34 is formed below the elastic body 30, and a side region 36 is formed on the lateral side of the elastic body 30, and the lower region 34 and the side region 36 are communicated with each other. Also, the fluid chamber 26 is formed by including the upper region 32, the lower region 34 and the side region 36 which are mutually communicated, and a supply/exhaust passage 28 is opened at least at one of the lower region 34 and the side region 36.SELECTED DRAWING: Figure 1 |
