American National Manufacturing, located in Covina, California, was founded in 1972. Specializing in sleeping surfaces, this company serves both the consumer market and medical services. Their line consists of sleeping surfaces, medical items, and related products: Hardside Waterbeds, Softside Waterbeds, Air Beds, Medical Beds, RF Welding, Sewing, Sit, Sleep & Store Nap Mats, SpaceLine Cots & Accessories, Gatte Safety Glasses & Gloves, and American Auto Bay Curtains.
The first four categories in the list are mattresses. The support for these is either water or air.
RF welding is the process used to make water bladders and air chambers as well as other waterbed and airbed components. The role of sewing in mattress manufacturing is well-known. American National Manufacturing also uses these services in contract manufacturing.
American National claims that it uses "the most cutting edge technology possible" in designing and making its airbeds and waterbeds. RF (radio frequency) welding is used in joining vinyl, rubber and other non-metallic materials for water-proof and air-proof seams.
