The record of using the “water bed” was as early as 3,000 years ago. At that time, the Persians slept in the sun-warm goatskin water bag, which was first designed by British doctor Dr. William Hoop in 1851. He found that in the treatment of various medical conditions, the pressure-reduced water surface is beneficial to the treatment effect, so the prototype of the water-filled mattress is made of rubber.Finally, an American named Charles Hall improved the mattress with high-tech materials in the 1960s, further improving the production process and gradually emerging rubber waterbeds. However, the characteristics of rubber are relatively easy to age, and the life span is only 2-3 years. Nowadays, with the development of science and technology, a specific environmentally friendly material has been developed, which is specially used for water beds. It is non-toxic, non-polluting and anti-stretching. Anti-aging, anti-stress, impact resistance, etc., the life cycle of water bags is more than 10 years.
