The Working Environment
If ergonomics specialists examined the home workstations of computer users
systematically, they would find many problems. Unfortunately, no standard
has yet prevented individual users from buying so-called “special computer ta-
bles”. The low-priced metal-tube frames with “practical rollers” (little stability),
“ergonomically retractable keyboard tray” (no wrist pad), “integrated PC case
holder and printer stand with paper shelf” (little stacking space and sometimes
little legroom), “swiveling mouse pad” (unstable and insufficient working space),
and “good view of the screen” (too close, too high) allow you to use a computer
for a short time only. They should not be used at professional terminal worksta-
tions as they hardly meet any criteria of the corresponding standards. You will
not find much of this kind of computer furniture in professional computer equip-
ment catalogs, because manufacturers indirectly keep an eye on the employees’
health by observing the minimum standards of computer workstations. Even
these minimum standards should be improved.

The Right Desk
A table at the wrong height strains arm and back muscles. The resulting cramped
posture especially strains the spine. Too little leg room can force an unnatural
body posture and cause disorders to the blood supply.
posture especially strains the spine. Too little leg room can force an unnatural
body posture and cause disorders to the blood supply.
Choosing the right table is very easy. It should be as wide and deep as possible.
An individual adjustment of the table height would be optimal. Working tables
at which you can change between sitting and standing by turning the table into
a writing stand, often just at the push of a button, are a luxury, but changing be-
tween a sitting and standing position brings relief.

The flexible arrangement of working materials requires a table top of at
least 160 x 80 cm.

Workstations made of several interlinked boards are recommended.
Tables that cannot be vertically adjusted must be 72 cm high. Tables that are
vertically adjustable must be between 68 and 76 cm high.

Even more width is needed for certain working tasks, such as CAD work-
stations. When changing between screen work and other kinds of work, at
least 200 cm is required.
