Its timeless design and innovative technology ensure optimum seating comfort and support health during prolonged periods of sitting. The chair has a synchronized tilt mechanism that enables synchronized movements of the backrest and seat, thereby promoting natural posture. The pneumatic seat height adjustment allows easy adaptation to individual needs, while adjustable armrests in height, width and depth provide optimum support for the forearm and reduce shoulder strain. An integrated, individually adjustable lumbar support provides support for the lower back, and the flexible two-part backrest dynamically adapts to the movements of the upper and lower body, which significantly increases sitting comfort.
