I'd go with some of those 1/2 inch closed cell foam exercise pads. They are inexpensive and come in 2x2 squares with interlocking edges to keep them together. I'll bet that would warm up the beds considerably.

Also, get a dog.

I knew that the bed pads in my new QS10 would not be thick enough for my comfort, I bought a 3" thick thermorest and sleep as well as my home bed.  Kind of pricey but I have other backpacking thermorest mattresses that are 30 years old and still work fine.
