Water pillow for natural balance. Clinical studies have shown that water base technology can alleviate neck discomfort and enhance overall sleep quality, giving you the greatest night's rest you've ever had. You won't ever need to adjust or fluff this pillow since the water will move with your head whether you sleep on your side, back, stomach, or alternate positions. A strong polyester fiber layer is placed on top of a completely sealed and insulated water bag to create this cushion. Its patented design provides a soft yet supportive surface that cradles your head in a gentle hug-like grip without adding any pressure. The water pillow also minimizes the number of times you will wake up throughout the night and gives your neck a more natural alignment, which helps to reduce tension in TMJ sufferers.
