Have a Coleman airbed set up in the basement. Bought a $20 300 count thread Mainstays brand bedsheet from WM and slapped it on the airbed.
The 2-3 days last week when we had hot weather, I retreated down to the basement to sleep. I found that the bedsheet couldn't retain any heat and my back was cold and I kept waking up.
Had to put a blanket (flanel) on top of the bedsheet for me to lay on and that worked.
Any suggestions for better bedsheet that retain heat?
