Why Did Waterbeds Disappear?

THE LIST -- The waterbed was invented in 1968 by Charles Hall, who presented it as his thesis project at San Francisco State University. His original prototype featured mattresses filled with starch and Jell-O (those early prototypes were failures). And because the mattress was meant to get rid of pressure points and make use of heat to relax the sleeper's muscles, it was made of vinyl, filled with water, and equipped it with a device that could regulate its temperature.
