Each Waterbase pillow has three unique layers for maximum comfort:
- A layer of super-soft, hypo-allergenic DuPont®polyester fiber floats over top of the water layer and provides outstanding comfort.
- A thermal insulator fully encases the water layer to prevent body heat from being drawn from the head, neck and shoulders. This is an essential component of the comfort of the pillow.
- A water pouch secured to the base of the pillow provides the responsive head and neck support. Easy to follow instructions show how much water to add for soft, medium and firm support. Use ordinary tap water. No chemical additives are required.
