It is important to make sure that wrists do not rest on the desk, or too heavily on a wrist rest. In these cases, a softer wrist rest would help lessen the pressure.Ī worker with a properly adjusted chair and desk might need only very light wrist support, if any. However, in other cases, individuals without a wrist rest would place their wrists on the sharp edges of the desk. This resulting condition may be what has led people to believe that wrist rests should not be used.

This pressure may cause carpal tunnel syndrome (CTS) to develop. On one side of the debate, it is known that leaning the wrists on a wrist rest or the edge of the desk for long periods can put a lot of pressure on the undersides of the wrists.
