I have had property adjacent to the Allegheny National Forest Hickory Creek Wilderness Area for 25 years now. For the first 16 years we had a older mobile home and than 11 years ago we built our cabin. Neither of those were ever heated when we were not there and our winters can go below zero often. We used normal "household" mattresses in both and have never had any problems. Well, yes if we get there late on a cold day, the bed is pretty cold when you first got in!
Too bad you don't know much about mattresses!
Where did the link go???????????????
