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.

Proper lighting can improve the visibility of the display and 
reduce eyestrain.

❖

Position the display panel or external monitor so that 
sunlight or bright indoor lighting does not reflect off the 
screen. Use tinted windows or shades to reduce glare.

❖

Avoid placing your computer in front of a bright light that 
could shine directly in your eyes.

❖

If possible, use soft, indirect lighting in your computer 
work area.
