An office chair is a type of seating designed for use in an office environment. It typically features a comfortable seat, backrest, and armrests, allowing users to work for extended periods without discomfort. Many office chairs are adjustable, enabling users to modify the height and tilt to suit their individual needs. These chairs often come with wheels for easy mobility and may include additional features like lumbar support to promote good posture. Ergonomic design is a key aspect of many office chairs, aiming to reduce strain on the body and enhance productivity during long hours of work.
