  • Patent number: 4984315
    Abstract: A pillow is provided for use by a woman during pregnancy. The pillow comprises a polyfill core having an adjustable bladder within one end of the pillow. The bladder may receive air through a hand pump so that the pillow may be adjusted to a woman's shape depending upon how the pillow is to be used. When the bladder is fully deflated, the pillow is of an oblong shape in elevation. When the bladder is filled with air, the pillow takes on an L-shaped elevation that can more closely hug a woman's body in certain lying and sitting positions. The bladder also includes a valve for holding or releasing the air from the pillow.
