Hyken Ergonomic Mesh Office Chair

Great office chair, got an upgraded one and looking to get rid of this one. Compare pricing with Staples as that's where I purchased from: "Adjustable armrests and seat height let you customize your seating position, while the mesh back regulates airflow for a cool working environment. Fine-tune recline resistance to your preference with the convenient tension knob and lock the back in a vertical position with the upright tilt lock. The ergonomic design and adjustable lumbar support contour to your body for maximum stability and comfort, and the five-star base with casters offers effortless mobility. "
