High Back Lever-Controlled Multi-Tilt Ergonomic Office Chair. The GGI-4430 OBUSForme ergonomic chair is a high-back multi-tilter with an interchangeable lumbar pad/headrest. The multi-tilter advantage means that the seat and backrest can be tilted separately. This gives you a wider range of options to protect your back. The options include a forward tilt of the backrest so that you remain supported even when you lean forward to work at a keyboard. The backrest can be locked in an infinite number of recline positions. Combined with the backrest height adjustment, this allows you to set your most comfortable seating position with unparalleled precision. Adjustments of the seat height, seat tilt and backrest tilt are controlled by independent levers under the seat. Adjustment of the backrest height is controlled by a concealed rachet system. The uniquely shaped polycarbonate backrest helps reduce back strain by guiding your back into a correct, healthy posture. The backrest continuously supports the lazy "S" curve of your spine, flexing as you move in any direction. The OBUSForme ergonomic chair features molded foam on the seat and backrest, a broad selection of arms, and a wide variety of durable, beautiful fabrics.
