Abstract: A postural health pillow comprising a three dimensionally rectangular outer casing which holds at least two discretely, proportionately filled casings/chambers. The bottom casing is filled with a sufficient quantity of grain hulls, or flowable particles filling, to elevate the head for proper spinal alignment for side sleeping and provide conforming support for the neck. The top casing is filled with a soft, compressible material, such as wool or down, to cushion the user's face and ear from the texture of the grain component and provide greater comfort. An aperture in the grain-filled casing allows the user to adjust the volume of fill for customizable sizing in fine increments. An opening in at least one end of the outer casing provides access for redirecting the fill in the bottom chamber to a position of maximum comfort, while in use, and fluffing the top component as required.
