We made sure we bought a high density memory foam topper which seems to almost eliminate the issues you describe above.Graham Derby said:I have had a memory foam topper for some years and i find it very good , but it too can get warm and hold the heat. Its also a bit more difficult to turn over as you sink your body shape into it. I could never get on with air beds
I also have in the house a Tempor mattres which when you first get in feels strange but your body heat soon lets you sink and that also holds your body heat in it.
As we have a fixed bed, we leave it on the bed at all times.RogerL said:Where do you all store these memory toppers, they seem quite bulky, at least as bulky as double sleeping bags ?
