Use a chair that provides good lower back support.
Keep your forearms horizontal with your wrists in a neutral, comfortable position
while you use the keyboard or mouse.

Let your upper arms hang naturally at your sides.
Sit erect, with your feet resting on the floor and your thighs level.
When sitting, make sure the weight of your legs is on your feet and not on the
front of your chair seat. Adjust your chairs height or use a footrest, if necessary,
to maintain proper posture.

type for extended periods of time. When you stop typing, try to do things that
use both hands.
