Water beds were awesome in the winter
Yes, as miniature hockey rinks.
I had a water bed for many years too - didn't hate it, but when my back started going south and I needed more support. My point is/ was, back in the day you could not go into any mall without finding at least one and usually several water bed stores. Water beds were just so "in" back then. Now days you would be hard pressed to find a water bed store in any major mall - not that they don't exist, but they definitely are not as popular as they once were.
