According to the embodiments, the controller includes a first receiving unit and a second receiving unit, and is capable of controlling a device to be controlled. The controller is in a first mode when in a first action state prior to the first receiving unit receiving a first operation, and the controller transitions to a second mode when the first receiving unit receives the first operation. The second receiving unit is in the first optical state in the first action state. The second receiving unit is in a second optical state in a second action state prior to the second receiving unit receiving a second operation in the second mode. The second receiving unit is in a third optical state in a third action state in which the second receiving unit has received the second operation in the second mode. The second optical state differs from the second optical state. The third optical state differs from the first optical state and differs from the third optical state. A controller and an electric furniture that are easier to use can be provided.

Controller and electric furniture

An air mattress for a bed, placed on a plurality of bottoms including a back bottom and used for the bed that performs a back raising operation for raising the back bottom, including air cells extending to a first direction and being arranged in parallel in a second direction; a first unit capable of inflating and deflating each of the air cells; and, a controller configured to control to alternately inflate and deflate the air cells by successively increasing and decreasing a pressure of air to be supplied to each of the air cells. The first unit inflate and deflate the air cells by n lines independent from each other, where n is equal to or greater than 3, and the controller controls inflation and deflation of air cells of one line during at least a part of a period in which a back bottom is being raised.

For each air cell, air is supplied and discharged through one of three lines independent of one another, every third cell being connected to the common line. The control unit controls inflation and deflation of air cells in turn in such an alternate manner that first the pressure of air in the air cells on the first line is increased and decreased, secondly the pressure of air in the air cells on the second line is increased and decreased, then the pressure of air in the air cells on the third line is increased and decreased. Thereafter, when the back tilt angle of the back bottom has reached a predetermined angle or greater, the control unit increases the pressure of air cells whose pressure is being lowered at that moment so as to produce an inflated mode similar to that of the other air cells. Then, while the back bottom is being raised, the control unit performs an inflation and deflation control of individual lines alternately on a cycle shorter than that in a normal control mode. With this arrangement, it is possible to prevent shrinkage of the air mattress in the bed longitudinal direction, prevent the bed user from sliding on the bed, and further prevent the bed user from getting bedsores.
