Achieve positive balance and clarity of mind seated upon the Martin Universal Feng Shui Drafting Height Chair. A single lever controls back rest, seat tilt, seat height, and free-float rear tilting. The large, comfortable padded foam back and seat provide a comfy resting place, as do the adjustable height armrests. Rest your feet on the large, adjustable chrome foot ring supported by a secure 5-star safety base, and roll easily on double-hooded multi-surface casters. The seating height is controlled by a pneumatic airlift mechanism, so you can arrive at your happy place while working comfortably.
