ABSTRACT:
A water based pillow includes a common fluid retaining envelope which is divided into two elongate regions having different fluid support and fluid dynamic characteristics. One region is basically uninterrupted while a second region has a series of heat seal islands joining opposed sides of the envelope. These heat seal islands reduce the amount of fluid retained in the second region. This second region is preferably the head support region and under load. Some fluid is displaced from this region and enters the first region which is preferably the neck support region. The amount of fluid in the envelope can be adjusted or set to maintain a thin layer of fluid beneath the user's head.
