Abstract: A lift chair includes a lift mechanism that maintains a continuous seating position during forward and elevated movement by supporting the occupant's seat, arms and back. The mobile section of the chair will also lower the occupant to the normal seating height. The gel cushion seating surface is attached at least to the moveable section of the lift chair. The gel cushion seating surface of the chair has a plurality of gel cushion cylinders arranged in a grid that provide a rhythmically changing support area at multiple points on the occupant's buttocks and thighs. This provides a comforting massage which reduces stress on the body associated with prolonged seating.

Abstract: A gel cushion seating, back, and neck surface is attached to or integrated with the seat and/or back sections of a chair. The gel cushion seating surface of the chair has a plurality of gel cushion cylinders arranged in an array to provide a rhythmically changing support area at multiple points on the occupant's back, neck, or buttocks and thighs. This provides a comforting massage, which reduces stress on the body associated with prolonged seating. The gel cushion back surface of the chair has a plurality of gel cushion cylinders arranged in a grid that provide a rhythmically changing support at multiple points on the occupant's lumbar and center back, also including the spine and neck. Various “cams” translate torque into the specified motion of gel cushion cylinders.
