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 figure 3-1.

Figure 3-1 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.
