The arm protector head rest is a half cylindrical shaped head rest with an outer and inner surface having a soft foam wall body. The head rest has support ridges of integral skin polyurethane foam on the inner surface sufficient to support the weight of a person's head when resting. A passageway exists between the inner surface and the bed such that a person may place their arms under the head rest and thereby under the resting head without the weight of the head on the arms. An alternate head rest uses U-shaped ribs in the wall to provide the structural support for the weight of the head. |
