Chapter 22. Office Ergonomics > Your Desk and Chair

Your Desk and Chair

There are three preferred ways to sit at your desk. Sitting upright is perhaps the most familiar posture when working at a computer. When seated, the angle between your upper and lower body should be approximately 90 degrees. Your back should be supported and erect. Your feet should be supported by the floor or a footrest. This is a good all-around posture for working at the computer.

A second popular sitting position is called reclining. In this position, you lean back in your chair. Make sure your back is fully supported and your buttocks are not shifted forward. This causes your lower back to not be supported. Your feet should be supported by the floor or a footrest. This is a good posture for viewing information on your monitor or for reading documents.
