wrist rest

wrist rest

A platform used to raise the wrist above keyboard level for typing. The correct height for a wrist rest is several inches higher than the keyboard (even though almost none of them are). The arms and wrist should be level, and the fingers should be pointing down towards the keyboard. See wrist support and wrist strap.

The Right Height
Wrist rests such as this one raise the wrists to a level that helps prevent carpal tunnel syndrome.
