4 Working in Comfort
• 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 - Your arms should be relaxed and loose, elbows close to your
sides, with forearms and hands approximately parallel to the floor.
• Wrists - Your wrists should be as straight as possible while using the
keyboard, mouse or trackball. They should not be bent sideways, or
more than 10 degrees up or down.
• Legs - Your thighs should be horizontal or angled slightly downward.
Your lower legs should be near a right angle to your thighs. Your feet
should rest flat on the floor. If necessary, use a footrest, but double
check that you have your seat height adjusted correctly before
getting a footrest.
• Head - Your head should be upright or tilted slightly forward. Avoid
working with your head or trunk twisted.
• Overall - Change your position frequently and take regular breaks to
avoid fatigue.
