Chapter 1. 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 can cause 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.

Height
Adjust the monitor so the top of the screen is at, or slightly below, eye level.
Place the monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to
24 in.), and position it so you can view it without having to twist your body.
Also position other equipment you use regularly, such as the telephone or a
mouse, within easy reach.
Glare and lighting
Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Even reflected light from shiny surfaces can
cause annoying reflections on your monitor screen. Place the monitor at right
