An orthopedic pillow comprises a padded member which has a hard block fully inserted inside. The padded member is made of resilient materials. The padded member's shape is roughly similar to that of a rectangular or hexagonal block; however, if looked right from its right or left side, the padded member has a symmetric or asymmetric bell shape. The length of the long side of the padded member is roughly equal to an adult's body's width. The hard block is made of non-resilient material. The hard block is able to tolerate, without rupturing and/or deformation, the gravity force on a mass of about 140 kg with a shape and size similar to those of a person's body. The shape of the hard block and of the padded member are similar, and their dimensions are proportional. The length of the long side of the hard block is also roughly equal to an adult's body's width. Both the padded member and the hard block have a flat bottom side. |
