The problem with mouse wrist rests is that they are stationary, but the hand must be moved around to move the mouse. This results in awkward hand/arm postures. The Fellowes Gliding Palm Support solves this problem — it easily slides on the desk surface to follow your hand movements. This keeps your hand and forearm in a natural, neutral alignment with one another. The palm support also features a channel in the middle section that relieves pressure on the carpal tunnel area.
