I use an inflatable - the insulmat insulated air mattress. I'm a side sleeper, and even the standard thermarest doesn't work for me (and the plain foam pads are worthless for me). Once I got this insulmat, I'll never go back. It is so much more comfortable. I have used mine for three years now with no leaks. I have used it on snow, and it is still reasonably warm (although not as warm as my standard thermarest).
The insulated air mattresses don't cost any more than the fancy models from thermarest. Mine cost me $54, and weighs 1.5 lb.
