• Head — Do not tilt your head forward by more
than 15 degrees, and try not to turn your head
toward the side.
• Back — While sitting at your work surface, make
sure your back is supported by the chair’s
backrest in an erect position or angled slightly
backwards.
• Arms — Make sure your arms and elbows are
relaxed and loose, with your upper arm
perpendicular to the floor or slightly forward.
Keep your forearms and hands approximately
parallel to the floor with elbows bent between
70 and 115 degrees. Keep your elbows close to
your sides (less than 20 degrees away from your
body).

Getting Started
• Legs — Your thighs should be horizontal or
angled slightly downward. Your lower legs
should be near a right angle to your thighs. Make
sure there is sufficient room under the work
surface for your legs.
• Feet — If after adjusting your chair you cannot
rest your feet comfortably on the floor, use a
footrest, preferably one that can be adjusted in
height and angle.
Overall
• Look away from the screen from time-to-time to
help reduce eyestrain. Focus on distant objects
briefly, and blink periodically to lubricate your
eyes. You also should have your eyes checked on
a regular basis and ensure your eyeglass
prescription is suitable for working on a monitor
screen.
