I don't know for sure, but have noticed that those "Tempur-pedic" type mattresses have started showing up in hotels and other places. If you could place your palm down on the mattress, and the imprint stayed there for a minute or so, then that's what it was. I assume that the company has been giving "great deals" to the big users to get their product out. We had one of them in a Holiday Inn up in Virginia, and it was very, very nice. Just a thought.
