Abstract
A pillow includes a first pillow cushion consisting essentially of a gelatinous elastomer that is sized and configured to support a head and neck of a person using the pillow cushion and a second pillow cushion coupled thereto. The pillow cushion has deformable wall members located and configured to define voids therebetween such that the deformable wall members may be displaced into adjacent voids upon deformation of the deformable wall members. The deformable wall members are configured to buckle when a pressure applied to a cushioning surface of the first pillow cushion, in a direction perpendicular to a first major surface, exceeds a threshold pressure level. A pillow cover covers the first pillow cushion and the second pillow cushion. A method of fabricating a pillow includes enclosing such first and second pillow cushions in a pillow cover.
