How office chairs are defined？
An office chair is a chair designed for use in an office setting, usually with adjustable height, adjustable backrest, adjustable armrests, etc. It is designed to provide the user with a comfortable seating position and good support to reduce fatigue and improve work efficiency. As defined by the American National Standards Institute (ANSI), an office chair is: a chair used in an office or other workplace that is designed to provide comfort and support to the user.
The American Association of Spine Surgeons (AOSS) recommends that office chairs have the following features: Adjustable Height: The seat height should be adjustable so that the user's feet are flat on the floor and the knees are at a 90-degree angle to the hips. Adjustable backrest: The backrest should be adjustable to provide support for the user's lower back. Adjustable armrests: The armrests should be adjustable in height and position to provide arm support.
The Ergonomics Society suggests that office chairs should have the following features: Seat cushion should be well cushioned and supportive. The backrest should provide lumbar and neck support. The armrests should be adjustable in height and position to provide arm support.
