Computer user comfort recommendations
Good Working Posture
❖Adjust your chair height: your feet should be flat on the
floor and the bottom of your thighs should be evenly
supported by the seat. If your feet cannot reach the floor,
use a foot rest. Avoid pressure points behind the knee or
under the thigh.
❖The space under your desk should be free of clutter so
that your legs and feet are not restricted, and you can
get close enough to your notebook and other items that
you use frequently.
❖Adjust the chair back rest: it should match the curve of
your back and provide comfortable back support.
❖Adjust the chair arm rests: they should be about the
same height as the keyboard and comfortably support
your arms, allowing your shoulders to relax.
❖When using the keyboard, it should be centered in front
of you.
❖The keyboard and pointing device should be close to
your elbow level. The keyboard should be flat so that
your wrists are straight when typing. However, if the
notebook is on a work surface that is above your elbow
height you may need to slope the notebook to keep your
wrists straight.
❖Work with relaxed shoulders.
