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.

The piece of furniture of claim 1 wherein the at least one lift bar comprises a first lift bar and a second lift bar, wherein the first lift bar is pivotally coupled to the at least one seat bar towards the front end of the at least one seat bar and the second lift bar is pivotally coupled to the at least one seat bar towards the back end of the at least one seat bar. 3. The piece of furniture of claim 2 wherein the first lift bar comprises a left first lift bar and a right first lift bar, the second lift bar comprises a left second lift bar and a right second lift bar, at least one connecting bar couples the left and right first lift bar, and the push bar is pivotally coupled to the at least one connecting bar. 4. The piece of furniture of claim 1 wherein the movable section comprises a backrest coupled to the back end of the at least one seat bar wherein the backrest extends vertically from the at least one seat bar. 5. The piece of furniture of claim 1 wherein the at least one movable seat portion is configured to be substantially parallel with a floor in the lowered position and the raised position. 6. The piece of furniture of claim 5 wherein the at least one movable seat portion remains substantially parallel with the floor as it rotates up and forward or down and backward between the lowered position and the raised position. 7. The piece of furniture of claim 1 further comprising a controller operatively coupled to the motor, wherein the controller is configured to operate the motor in a first direction to move the movable section from the first position to the second position and to operate the motor in a second direction to move the movable section from the second position to the first position. 8. The piece of furniture of claim 1 further comprising a foot rest that is movable between a horizontal position and a vertical position and operatively coupled to the stationary section. 9. The piece of furniture of claim 8 further comprising a controller operatively coupled to the motor, wherein the controller is configured to operate the motor in a first direction to move the movable section from the first position to the second position and to operate the motor in a second direction to move the movable section from the second position to the first position and, wherein the controller is further configured to move the foot rest between the horizontal position and vertical position. 10. The piece of furniture of claim 1 wherein the movable section further comprises a pair of arm rests operatively coupled to the at least one seat bar and movable between the lowered position and the raised position. 11. The piece of furniture of claim 1 further comprising a pair of armrests operatively coupled to the movable section. 12. The piece of furniture of claim 11 wherein at least one of the armrests comprises a hollowed portion. 13. The piece of furniture of claim 1 wherein the piece of furniture is a chair. 14. A chair comprising: a stationary section;a movable section; andmeans for lifting the moveable section with respect to the stationary section,the stationary section comprising: a stationary seat portion comprising a first foam cushion;the movable section comprising: at least one seat bar having a front end and a back end;at least one movable seat portion comprising a second foam cushion coupled to the front end of the at least one seat bar, wherein the at least one movable seat portion is movable between a rearward, lowered position and a forward, raised position, where when the movable seat portion is in the lowered position the first foam cushion forms a planar seating surface with the second foam cushion and in the forward, raised position the second foam cushion overlaps at least a part of the first foam cushion to facilitate an occupant transitioning between seated and standing; andat least one backrest coupled to the back end of the at least one seat bar, wherein the means for lifting causes the at least one seat bar to move between a first position and a second position such that the seat bar rotates between the lowered position and the raised position while the stationary seat portion remains stationary and the movable seat portion remains substantially parallel with a floor. 15. A piece of furniture, comprising a stationary seat portion including at least a first foam cushion;a movable seat portion including at least a second foam cushion; anda parallelogram linkage mechanism operatively coupling the stationary seat portion and the movable seat portion to move the movable seat portion between a lowered position and a raised position wherein the first foam cushion and the second foam cushion together form a planar seating surface when in the lowered position,wherein, as the parallelogram linkage mechanism rotates the movable portion including the second foam cushion from the lowered position upward and forward to an upward and forward raised position to facilitate transitioning an occupant from a seated position to a standing position and from the upward and forward raised position to the lowered position to facilitate transitioning the occupant from the standing position to the seated position, the movable portion remains substantially parallel to a floor, and the stationary seat portion remains substantially stationary.
