Using the Right Furniture

electing a good desk and using the right type

f chair can make a big difference in your level

f comfort. When you set up your furniture,

onsider 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 to 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.
