I really love our new setters chair.  It has five wheels, so it rolls very smoothly across the floor.  And another really cool feature about this chair is that you can adjust the seat anywhere from 16 to 22 inches by using the foot control disk at the bottom or the lever on the side.  And then there's the single touch tilt adjustment and an easy to turn knob to adjust your lumbar height. Because it's so ergonomic, you'll find that it's very comfortable and it reduces fatigue even when you're at the bench for an extended length of time.
