<p>A water bag for a head pillow has been modified by providing a series of tack seals located interior to the periphery of the water bag. The tack seals reduce the volume of the water bag and control the displacement of the water when a person's head is supported on the pillow. In a preferred embodiment, part of the water bag is deprived or the bag is restricted to provide additional support to the areas adjacent the deprived area. This has particular application as a chiropractic pillow.</p> |
