Safety & Comfort Guide
Using a Palm Rest
A palm rest (sometimes called a wrist rest) is designed to
provide support during pauses, not during typing or
pointing. While typing or while using a pointing device,
keep your wrists free to move and not anchored or resting
on a palm rest, the work surface, or your thighs. Resting
your palms while typing may be harmful because it can
cause you to bend and hold your wrists and fingers back.
It can also apply pressure to the underside of your wrists.
Refer to Chapter 2, in the section "Forearms, Wrists, and
Hands."
