The ergonomic mesh back office chair is a great addition to any workspace or office. A curved mesh back design creates a breathable, well-ventilated backrest with added lumbar support that helps keep you comfortable during your workday. The breathable padded seat is thick, resilient, and constructed of high-quality foam and breathable mesh cloth. The gas lift makes it easier to raise or lower the seat for the perfect position. In addition, the arms are connected to the back of the chair, so you don't feel restricted during those long workdays.
