A pillow includes a head support, a neck support, and an opening extending entirely through a central portion of the pillow. The head support includes a top surface and a bottom surface, and defines a first height extending between the top and bottom surfaces. The neck support is coupled to the head support and includes a top surface and a bottom surface. The top surface has a central portion and side portions. The central portion defines a second height extending between a base of the central portion and the bottom surface, and each of the side portions defines a third height extending between an apex of the respective side surface and the bottom surface. The third height is greater than the first and second heights.
