Stay comfortable on the job with the Web Chair from Boss Office Products. Made from a combination of leather and polyurethane, the seat upholstery provides both softness and durability. The breathable mesh back conforms to each individual's shape, distributing weight evenly. Because mesh stretches over time, this chair features a web tension knob that lets you tighten or loosen the mesh material with a few simple twists. Adjust the height of your seat or armrests to find just the right position. A tilt-tension control lets you choose how easily your chair reclines. Rolls easily on five dual-wheel casters.
