Yah,I ditto the above.... (there's another thread on this too somewhere)
On top of the wooden base floor, 2 layers of bubble foil (insulation) - Base Camp Inn green pad - 2" form pad - heating pad - regular mattress pad - fitted flannel bottom sheet - Duvet covered 750 Down quilt.
Perfect, like Joan, don't like to make bed, quilt is Quick N'Easy
In combination with the heat pad and the heater it's worked fine more than once, down to 13F or a little lower...
A little PITA in fitting the bottom sheet.
I tried fitting sheet to the top foam pad but reg fitted mattress pad's elastic is too strong and it bunches it up in the corners. Still works fine, just a visual annoyance, heheh.
I just try to slide the big pad forward towards the front and lie on belly to fit the back corners... small price and a few bumps, but quick and relatively painless.
Love the Flannel, using them for the past 30 yrs (LLBean's of course, LOL)
2 pillows, but probably need 2 more...
