Working in Comfort
Sitting in one position for long periods can be uncomfortable. To minimize the potential
for physical discomfort or injury, it's important that you maintain proper posture.
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.
