Make sure your forearm and wrist are parallel to the ground. The hand should be straight in relation to the forearm, not flexed up or down. Keeping your hands in this position puts less pressure on the nerves and tendons passing through your wrist, thus avoiding irritation. You can accomplish this by adjusting the height of your chair until your forearms and hands are in the right posture. A good wrist rest will insure that your hands will not flex.

Your eyes should be level with the top of the monitor. This will insure that your head and neck are in a more natural position. Your head and neck should not be too far forward or backward. Use phone books or reams of paper to make the adjustment.

Feet should be flat on the floor. If they do not touch the floor or if you tend to use the base of the chair to rest your feet, a footrest should be used. A footrest also can be used to push you back into the chair providing more back support.

Your body should be open. All joints should be greater than 90 degrees.

Your monitor should be directly in front of you. You should not be twisting your body left or right in order to work at your computer.
