Ergonomic office chair The S-shaped backrest of the desk chair provides excellent lumbar support. The widened design of the backrest adapts completely to your back and firmly supports your shoulder vertebrae. Using a swivel chair effectively prevents back pain by maintaining the natural curvature of the spine and correcting your sitting posture. What is adjustable With the rocking function, you can relax on this office chair for a moment and then continue working. You can adjust the lumbar support (6 cm), armrests, and height (10 cm) to your liking to achieve the most perfect sitting position possible. The day is over! Save space by lowering the seat height and armrests to slide the computer chair under your desk. High-quality materials The seat cushion of the ergonomic office chair is made of high-quality foam. It is moderately soft and firm, offering a comfortable seating experience. The backrest is made of special highly elastic nylon mesh, which is breathable and strong. Thanks to the quiet casters, the chair can be moved smoothly and protects the floor from scratches. All these details make this executive office chair even more durable.
