"A waterbed shapes itself exactly to every part of your body providing even distribution of pressure and a restful nights sleep. Waterbed sleepers move only occasionally during the night, about once an hour. People suffering chronic pain appreciate the health characteristics of a waterbed. Long-term quality: Since water does not wear out, waterbeds also sleep the same way after many years, as they do the first night. Waterbeds provide a cleaner sleeping environment: Want to sleep with the critter below? Dust-mites are a microscopic relative of spiders that live in our furniture and carpets. Theythrive in our bedrooms because of the heat and warmth we give off. Dust mites feed off our dead skin cells. Unfortunately their droppings have a protein that many people are allergic to. Dust mites live about six weeks and female dust mites lay between 60 to 80 eggs during their lifetime. Dust mites have no natural predator so they just keep multiplying. A full size mattress has approximately two million dust mites in it. A gram of dust has 1,000 dust mites in it. Old pillows may have as much as 10% of their weight made up of dead dust mites and droppings. Fortunately for owners of traditional waterbeds, they are easy to take care of. Simply wash all bedlinens weekly in water that is over 140 degrees temperature and wipe the mattress down with mild soap solution, and rinse. Periodic washing of pillows is highly recommended. Special pillow covers are also available to help prevent pillow reinfestation."
