Seating and posture
When using your computer, maintain good posture with your
body relaxed and your weight distributed evenly. Proper seating is
a primary factor in reducing work strain. Some people find a
backless chair more comfortable than a conventional chair.
Whichever type you choose, use the following guidelines to adjust
your chair for maximum computing comfort.
Correct posture and positioning of the computer
❖
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.
