Abstract: A pillow has two intersecting channels formed in its upper face. One channel accommodates the user's head, the other the user's neck. A relatively hard object is located in or under the first channel and also adjacent the second channel. The relatively hard object functions so as to make it uncomfortable for a user to rest the back of the user's head on the hard object, while not being relatively uncomfortable if the user moves his/her head to one side or the other. The pillow is designed so that when the user's head is on one side or the other thereof, a part of the pillow engages the user's lower jaw, causing the user's mouth to be closed.
