I read an earlier thread about foam mattresses. I went to Wal-Mart and purchased a 4" thick memory foam mattress topper. It is actually 2.5 inches of medium density foam and 1.5 inches of memory foam. This seemed perfect for my teardrop trailer. It is not designed to be a stand alone mattress, but I put it on the hardwood floor of my living room and it was pretty darn comfortable.
My wife and I spent the night in the living room on this mattress. I slept great except for the fact that the foam mattress seemed to be drawing the heat out of my body. I usually sleep very warm and have never experienced this before. Usually any mattress I sleep on warms up from my body heat and I sleep under just a sheet and a light blanket all night. But this foam bed never warmed up. It was cold all night even though I kept piling on the blankets. I finally put blankets between me and the mattress and then I slept fine. I have a raised foundation home and there is no insulation under the wood floor. Just 2' of crawlspace. Maybe it was the wood floor. But then, the floor of my tear will not be insulated either. And there is air below the tear.
My question is this. . . Has anyone else experienced having their foam bed feel cold? My wife says get a down cover for the foam bed. I feel silly getting a mattress cover for my mattress cover. If the down cover doesn't work, I guess we could just cover that as well. This could go on forever. I think the foam is acting like a great big "heat sink". But maybe it is totally the fault of the floor. Waddayathink?
