Bed Rock...of Non-Flinstone Origins

Current trend is the increasing popularity of stone beds reputed as being good for people with back pains. Ages ago, stone beds were common in Asia, but apparently, they still are for some folk who are trying to bring the practice back as well as to the West. In speaking to my mother, I also learned that her caretaker (nanny) slept on one but it was more narrow and smaller than the modern ones. Considering modern trends, that's not surprising. Modern stone beds don't use stone exclusively like days of old. There are mica versions now!
