Abstract: An orthopedic pillow is a monolithic foam structure. Spaced apart depressed top and bottom surfaces are continuous with, and are extensive between the side surfaces. The top and bottom surfaces are each formed as a plurality of side-by-side longitudinal ribs parallel with the long side surfaces. Each one of the ribs protrudes outwardly from the apparatus and is a major portion of a semi-circle in shape. The physical conformation of the apparatus is such, that with the long side surfaces resting on a mattress, the tips of the ribs are initially spaced apart from the mattress, and with a head's weight resting on the top surface, the ribs of the top surface are compressed, and the ribs of the bottom surface are urged toward the mattress providing compressive resistance proportional to the compressive force.
