Correct placement of you monitor and keyboard can reduce eye, arm, back, shoulder and neck fatigue. Improper posture caused by an inadequate chair or a chair that is improperly adjusted along with awkward hand and keyboard positions can result in early day fatigue. Long periods of repetitive work can lead to hand, neck, and back pain and ultimately injury. Ergonomics is the applied science focused on human use. Ergonomics provides an array of information critical to the design and proper use of office equipment, furniture and computer accessories.

Chair Position:

Adjust the height of your chair so your upper thighs are parallel to the floor. Adjust the back support so your back is firmly supported and angled slightly backward while your feet are fully supported on the floor or a footrest.

Keyboard Position:

The height for your keyboard and mouse, should be set so your hands, wrists and forearms are in a straight line and are level with your elbows when your arms are comfortably at your sides.

Monitor Position:

The top of the monitor screen should be even with your forehead and directly in front of you. A good rule of thumb is an arms length distance. Your eyes should look slightly dowward, approximately 15º to 30º.

If you use bifocals, lower the monitor below eye level and turn the screen upward, tilt the screen back 30º to 45º.

Remember that even if your workstation is set up properly, you can still experience muscle fatigue from being in the same position too long. Muscles are meant for movement not to hold static positions. It is important to periodically adjust your chair and change positions to help avoid fatigue. Be sure to stand and stretch your back and arms periodically.
