Used Herman Miller Ambi office chairs with 49 different ergonomic positions to fit anyone for any task. There's virtually nothing you can't adjust on a Herman Miller Ambi office chair, seat and backrest height, seat depth, armrest height and angle, tilt tension and reclining angle. All Ambi chair controls are easy and intuitive - easy to reach and have identifying icons and raised touch points. The Ambi task chair was designed for people who sit at computers - lean forward and back over and over. The tilt control makes the seat and back move in sync, keep weight distributed evenly, improve circulation and relax muscles. The lumbar support always stays in position. Our used Herman Miller Ambi chairs are rated 4 of 5 and are located in Los Angeles. The price does not include delivery.
