  • Publication number: 20120023676
    Abstract: An improved orthopedic head pillow enables a user to maintain correct spinal alignment while sleeping in a variety of positions. The pillow has a stuffed resilient body formed from cloth cover having a generally rectangular central aperture. For one embodiment, pillow dimensions are about 48 cm by 76 cm, with a 10 cm by 15 cm central aperture that is aligned so that its longitudinal axis is aligned with the pillow's lateral axis of symmetry. For back sleepers, the back of the head is cushioned by the edges of the aperture yet positioned at mattress level. Side sleepers can use either side portion of the pillow to the side of the aperture, with the head being centered on the side portion and the face facing either the aperture or the edge of the pillow. Stomach sleepers can place the side of the face on a downward slope adjacent the aperture.
