PROBLEM TO BE SOLVED: To avoid the number of cables for connecting a bedding body to a controller from being increased, even if a vibration block is provided in the bedding body for adding a massaging function thereto, more than a case where the vibration block is not provided. SOLUTION: When a bedding body is used as a heat bedding, temperature information from temperature sensors 12 and 13 contained in the bedding body is transmitted to the detecting circuits 23 and 24 of a controller. Thus, source current supplied to heaters 10 and 11 in accordance with the information is controlled and the temperature of a part heated by the heaters 10 and 11 is maintained at a set temperature. A relay 20 is connected in parallel with the temperature sensor 13. Source current from the controller is supplied to a cable for supplying temperature information from the temperature sensor 13 to the detecting circuit 24 of the controller, so that the relay 20 is energized to close its contacts 18 and 19 and supply the source current to a vibration block 14 through the contacts.
