Arranging your workspace
To get the most from your computer, arrange both the equipment
you use and your work area to suit your needs and the kind of
work you do. Your comfort is of foremost importance, but light
sources, air circulation, and the location of electrical outlets also can
affect the way you arrange your workspace.
Comfort
Although no single working position is ideal for everyone, here are
a few guidelines to help you find a position that suits you best.
Sitting in the same position for a long time causes fatigue. A good
chair can make a big difference. The backrest and seat should
adjust independently and provide good support. The seat should
have a curved front to relieve pressure on the thighs. Adjust the
seat so that your thighs are parallel to the floor and your feet are
either flat on the floor or on a footrest.
When using the keyboard, keep your forearms parallel to the floor
and your wrists in a neutral, comfortable position. Try to keep a
light touch on the keyboard and your hands and fingers relaxed.
You can change the angle of the keyboard for maximum comfort by
adjusting the position of the keyboard feet.
