Legends say that in the ancient times, royalty slept on beds made of goat skin and are filled with water. But In the 1800s, the water bed mattress was first used in aid of medicine. British Dr. Hooper saw that it had medicinal benefits which helped patients with arthritis or rheumatism. And then in 1960, Charles Hall from America, reinvented the waterbed mattress and called it the Pleasure Pit. The hippies loved it and waterbeds were usually associated with them. But his reinvention became the basis of how the bed is made today.
