ABSTRACT:
Nonrotating vibrator motors are mounted on a rigid member in furniture. Electric power at different frequencies or energy levels is supplied to the respective vibrator motors. Frequency differences in the vibrations result in moving interference waves being produced in the rigid member which waves are imparted to the user of the furniture who experiences a massaging effect. Means are provided for enabling the user to control the frequency differential and amplitudes of the driving currents.
