We have a good comfortable king sized conventional mattress bed, but man, when we lived in our house we lived in before buying our retirement home, we had a wonderful water bed. It had a double heaters, strips sewn into or molded or whatever that gave it increased support, it was PERFECT! My wife bought the bedroom set way up in the mountains, I had to rent a truck to move it to the house. It was PERFECT too. We bought the mattress in town the best one they had when they still had water bed stores around. Man, I was just like a little mouse hunkered down in a paper sack when I went to beddy-by. When we got rid of it, I kept a small kind of dresser/storage cabinet just to remind me of my old bed. Out bedroom TV sits atop it to this day.
