Abstract
A device for creating vibration within a chair which provides a therapeutic benefit to users. The chair has a control for adjusting the frequency of the vibrations and the amplitude of the vibrations, providing a wide variety of therapeutic results. The circuit powering the vibration sources within the chair employs a unique design that acts as a heat sink, effectively drawing heat away from the vibration sources and thus extending their useful life. The vibration sources may be incorporated into the seating furniture of vehicles such as automobiles or airplanes to provide relief from the strain associated with trips of extended duration. The structure has a sufficiently low profile to lend itself to placement in seating used in vehicles which have rather stringent dimensional requirements.
