The massage controller is adapted, in a calibration mode of operation, to drive the at least one massage actuator with a test signal for excitation of the mattress, to receive measured values which represent a response of the mattress to the excitation with the test signal, and to determine, on the basis of the measured values and the test signal, a response characteristic represented by an oscillation response of the massage actuator and the mattress. In addition, the massage controller is adapted to control, in a massage mode of operation, the at least one massage actuator based on an adjustable massage parameter and the oscillation response.
