Correct posture and positioning of the computer
Whichever type you choose, use the following guidelines to
adjust your chair for maximum computing comfort.
❖
Position your chair so that the keyboard is at or slightly
below the level of your elbow. You should be able to type
comfortably with your shoulders relaxed and your
forearms parallel to the floor.
If you are using a conventional chair:
❖
Your knees should be slightly higher than your hips. If
necessary, use a footrest to raise the level of your knees
and ease the pressure on the back of your thighs.
❖
Adjust the back of your chair so that it supports the lower
curve of your spine. If necessary, use a cushion to
provide extra back support. Lower-back-support
cushions are available at many office supply stores.
❖
Sit with your back straight so that your knees, hips, and
elbows form approximately 90-degree angles when you
work. Do not slump forward or lean back too far.
