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 and to the following figure.
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 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.
