Since you’ll be sitting most of the time you use your computer,

it’s important to have a good chair. An adjustable chair allows

you to support your body in the correct position. Make sure the

chair supports your lower back; the backrest should fit the

curvature of your spine. To reduce fatigue, try to use a chair

with adjustable, padded armrests so you can occasionally rest

your arms while you work.

Make sure the seat and backrest are wide enough so you can sit

in a variety of positions throughout the day. Also leave enough

room under the work surface so you can vary the position of

your legs.

Adjust the height of your chair so when you are using the

keyboard or mouse your upper arms are vertical and your

forearms and wrists are horizontal. For good circulation, your

feet should rest flat on the floor with your lower legs vertical

and your knees level with your hips. You may need to use a

footrest to maintain the correct alignment for your legs.

Positioning Your Monitor

Place the monitor so it is directly in front of you

with the top of the screen slightly below eye level

when you are sitting at the computer. You may want to place it

on top of the computer or on a stand.

Your line of sight to the screen should be about 10 to 20 degrees

below the horizontal. If the monitor has a tilt and swivel base,

you can adjust the position of the monitor screen for the best

viewing angle.

Sit about an arm’s length or more away from the monitor. The

most comfortable viewing distance depends on the size of the

screen characters and your ability to focus on the display.

Adjust the monitor’s brightness and contrast controls to

maximize image clarity, and keep the screen clean.
