— Do not use armrests for work that requires a lot of
arm movements, as they inhibit mobility.Armrests
are sometimes useful to give support for the whole
arm. In this case, supporting the whole arm is better
than just supporting the wrist.
— After adjusting the seat height so that the work is
slightly below the elbow, the feet may dangle.This
happens when the working height is not adjustable.
In this case, use a footrest.
