Abstract: A pillow designed to be wholly and fully adjustable. It is achieved by a design that is both curved and asymmetric at the same time. It resembles a shrimp tail. This unique design affords for a rapid adjustment to a wide range of anatomical variations and sleeping conditions. Simply turning the pillow clockwise or counter clockwise changes the height and the width of the pillow until the user's neck and head is aligned with the spine in a comfortable anatomically correct sleeping position. The pillow can be made in small, medium or large and can be made in soft, medium or firm.
