Because most mattresses are filled with a foam core or an innerspring system, a waterbed offers a unique sleeping experience. Waterbeds became commercially available in the 1970s and became immensely popular in the 1980s. BPL Air Mattress is an alternating mattress replacement system designed for prevention of pressure ulcers. The product works by sequentially inflating and deflating the alternate air bubbles. The inflated air cells provide pressure to support the user whilst the deflated cells provide relief for the skin above them.
