Seating and posture
The height of your chair in relation to the computer and keyboard as well
as the support it gives your body are primary factors in reducing work
strain. Refer to the following tips.
1
90°
Posture and positioning of the computer
Place 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.
Your knees should be slightly higher than your hips. If necessary, use a
foot rest (see "1" in the illustration) to raise the level of your knees to
ease pressure on the back of your thighs.
Adjust the back of your chair so it supports the lower curve of your spine.
Sit 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.
