Abstract: An ergonomic, arm-positioning pillow includes an ornamental design including an upper portion having a top surface for supporting the head of a sleeper and a bottom portion having a lower surface for supporting the arm-positioning pillow and having a first space extending at an oblique angle from a first space located along the lower surface for receiving an arm therein and supporting the sleeper to position the arm for managing the amount of pressure applied to the arm, and a second space located in the lower surface for receiving a second arm or for receiving the second arm to provide for ambidextrous use of the arm-positioning pillow and to obtain improved sleep performance in the form of reduced snoring and sleep apnea.
