The maximum permissible load-carrying capacity
of the desk is not exceeded.

Optimum desktop height
The adjustment to the optimum desktop height

posture at the workstation. The correct desktop
height setting for the workstation can be found in the
workstation analysis (pursuant to the German
Occupational Safety and Health Act, the German VDU
Ordinance, or accident prevention regulations, for
example). See also BGI 650: Screen and office
workstations. Design guidelines.
