Are you looking for the ultimate seating comfort in the office? The Sitag Xilium DuoBack swivel chairs offer the perfect solution for those who spend long hours at their desk. The Xilium DuoBack has been developed with a clear focus on ergonomics and offers excellent comfort and support. People have two shoulder blades and two sides of the lumbar region, but rarely move symmetrically. Conventional office chairs with a single backrest do not take this into account. Sitag offers an innovative answer to this problem with the Xilium DuoBack. The DuoBack backrest, which is unique in the world and consists of two movable parts, means that every movement of your back can be perfectly supported. This dual backrest reduces tension in the shoulders, relieves pressure on the spine and prevents stiff lumbar muscles - truly ergonomics in action. The Xilium DuoBack has a wide range of adjustment options for the seat and backrest. Thanks to the adjustable armrests, the integrated headrest for additional neck support, the liftmatic comfort height adjustment, the advanced synchronous system and the body weight adjustment using a rotary knob (45-150 kg), you will experience optimum comfort without uncomfortable sitting. The sturdy construction and durable materials for which the Sitag name stands guarantee the chair's longevity. The hard floor castors supplied as standard also protect your floors. This Swissmade-certified product combines high material quality with maximum comfort. Its elegant design and modern lines blend seamlessly into any professional office environment. Whether in the office, home office or conference room, the Xilium DuoBack ensures that you work in comfort and support to stay productive and focused.
