For those who spend a lot of time sitting, it's important to focus on comfort and functionality when purchasing an office chair. Thanks to the Sitness Open X office chair with synchronous mechanism, even stressful workdays where you don't get much fresh air become manageable. The seat angle is linked to the backrest angle, allowing it to move with you when you lean back. The synchronous mechanism promotes active sitting, which stimulates blood circulation and nutrient supply to the spine. This is especially useful when the chair is used by a larger group of people, as the tension adjustment allows the backrest's counterpressure to adapt to the respective body weight. The chair features a backrest that is 580 millimeters high, which is relatively medium in height. It is adjustable within a range of 60 millimeters, allowing you to customize it to your body size. The newly designed mesh backrest, Window, provides breathability and creates a comfortable seating climate. Anyone who often sits at their desk for extended periods will benefit from the comfortable molded seat. Your new office chair has a seat depth adjustment and can be precisely adapted in height to leg length and sitting posture using a top lift. Healthy work in the office requires sufficient movement and avoids rigid sitting positions. The 3D seat joint (Sitness joint) achieves this by allowing three-dimensional mobility of the seat surface. This way, you keep your musculoskeletal system fit and your blood circulation active even while sitting. The comfort padding ensures pleasant sitting, even on longer days in the office. The Sitness Open X office chair features height and width adjustable armrests, which help prevent neck and shoulder tension and enhance your seating comfort. The beautiful design is completed with an aluminum base.
