This study discusses the effectiveness of using a balance chair and adjusting a desk height and working position for maintaining seating posture during light-duty work. It is important for a worker to maintain good posture to improve work efficiency and protect his or her health. However, the worker’s body trunk tends to lean forward unconsciously when he or she is working on an ordinary chair. Meanwhile, a person sitting on a balance chair, which comprises a forward-declined seat and a knee pad, can maintain a posture that resembles that of standing. This study measures the body trunk angles of a subject performing light-duty work while seated on an ordinary chair and a balance chair and discusses the influence of desk height and working position.
