The obvious conclusion is the pillow has to keep you cool while you sleep. How does this pillow have to be constructed to be able to maintain a cool temperature? For one thing, it has to allow the air to flow through the pillow. This may be accomplished by the pillow being made of breathable materials that will regulate the heat and keep the pillow cool. It must be able to disperse body heat to keep the pillow cool as well. The pillow should give the consumer ample neck and head support so the consumer can sink into the pillow and not wake up until morning. The client should be able to sleep in one position all night long. This will prevent the consumer from tossing and turning which will keep the body temperature down allowing the pillow to remain cool.
