Abstract: A training pillow to assist in teaching a person not to sleep face-down has base a portion for supporting the back of the head when lying face-up on a sleeping surface and two side portions which project substantially diagonally from the base portion and away from the sleeping surface. The pillow can make it awkward and/or uncomfortable for the person to sleep face-down and thereby arousing the person into a conscious state to remind the person not to sleep face-down. Additionally, flipping the pillow over will present an awkward and/or uncomfortable sleeping surface. However, when a person rolls to the side, the corresponding side of the person's head causes the appropriate side portion to move into contact with the sleeping surface, while the base portion and the opposite side portion are lifted away from the sleeping surface.
