Neoair ultralight or Exped Synmat 7 both are great backpack pads. Bad bad luck with a Big Agnes as it developed about a thousand leaks the third night out. The bathtub test showed bubbles all over a section of it. No trust after that.
My my favorite camp model is a double wide ancient Thermarest folded to make a single width double thickness bed 4" or 5"' thick. It is the best mattress I ever sleep on. Packs to about a foot in diameter by 2' wide.
