The 5000 shines in every respect: High in comfort. Attractive in design. Ergonomically correct functions. And, not least important, high performance for your money. With the well balanced pattern of movement of the Synchron tilt, Nozag springs in the seat and a spring arrangement in the backrest (patent pending) – the 5000 provides comfort all day long. Even when the chair’s tilt is locked, there is a flexible dynamic in the backrest. Sitting height, seat depth and backrest height are adjustable. Two different armrests are available as options. Safeback is standard!
