A controller, which serves as a pressure-feeding control portion, drives an air pump to pressure-feed air to massage airbags located in a seat. In addition, the controller, which serves as an inflation-deflation control portion, performs massage control that inflates and deflates the airbags while keeping the air pump driven by controlling the operation of intake-discharge valves in second flow passage (branch lines), which connects the air pump to the airbags. Furthermore, the controller, which serves as a decompression control portion, opens a discharge valve, which is located upstream of the intake-discharge valves, in a state in which the airbags are deflated during the massage control.
