PROBLEM TO BE SOLVED: To provide a mattress device which can reduce time required from an instruction made for pressure adjustment of air bags and to start of the pressure adjustment.SOLUTION: The mattress device includes: a first air bag 10 and a second air bag 20 constituting mattresses respectively; a compressor 37; a first opening/closing valve 32 and a second opening/closing valve 33 arranged in the first air bag 10 and the second air bag 20 respectively; a connection part (chamber 34) connecting the compressor 37 and both opening/closing valves mutually; a pressure sensor 36 connected to the connection part; and a control part 31. When the control part 31 adjusts pressure values of the first air bag 10 and the second air bag 20 to a first designated pressure value and a second designated pressure value respectively, the control part 31 opens the first opening/closing valve 32 and the second opening/closing valve 33 to circulate air between the first air bag 10 and the second air bag 20. After that, the control part 31 adjusts the pressure values of the first air bag 10 and the second air bag 20 to the first designated pressure value and the second designated pressure value respectively.SELECTED DRAWING: Figure 4 |
