This is an absolutely gorgeous office chair. It's modern and stylish, and is designed for maximum comfort. This chair has a complete range of motion. It swivels in a complete 360 degree circle, and it is equipped with a pneumatic gas lift, so you can raise and lower the chair with a simple pull of a lever. It tilts back, but also has a tilt lock, so you can keep the chair upright if you like. It also has a tilt tension control, so you can make the tilt as stiff or flexible as you like. In addition to a great range of adjustment, this fabric task chair was ergonomically crafted to keep you comfortable for hours of long sitting. To begin, this chair features a contoured padded seat. Seating is constructed of a black mesh fabric that is very breathable. The armrests are textured to be ultra comfortable and are perfectly positioned for resting your arms while typing at a computer. Plus there are reflective accents on the chair arms and on the seat back that make the chair look fantastic in any room. The chair is also trimmed in duraskin PVC for a clean look and for extra strength to resist tears if you back up into a cabinet or corner. Check out the fantastic chrome base on this chair. Most cheap office chairs have a plain black nylon base. But this chair features a heavy-duty "5 star" chrome base with rolling casters. The heavy-duty double wheels are extra sturdy, and hooded for your safety. The seat size is 18 inches at its widest point (between the arm rests) and the depth of the seat is 18.5 inches. The back is 18 inches at its widest point and 18.5 inches high. The seat adjusts from approximately 17 inches to 21 inches high. Some assembly is required.
