Using the Right Furniture
Selecting a good desk and using the right type
of chair can make a big difference in your level
of comfort. When you set up your furniture,
consider these suggestions:
An L- or U-shaped desk configuration works well because it
provides ample space to hold your computer equipment and
work materials while keeping everything within easy reach. A
split-level desk or one with a pull-out keyboard drawer lets
you place the keyboard in a comfortable typing position.
Since you’ll usually be sitting when 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.
