The seat and backrest are mounted on a heavy-duty mechanism, with individual gas-spring cylinders for independent seat and backrest control. The deeply contoured seat forces you to sit all the way back in the seat, ensuring that the sculptured backrest in firm contact with the lumbar region of your back.
The unique design of the mechanism, seat, and backrest, allows a range of movement with the backrest at all times, maintaining contact and support of your back. With the control lever in the "Free-Float" position, the seat and the backrest will follow you as you lean forward and back on the stool. In addition, the waterfall front allows better circulation in the lower leg.
