Same here on the age and ground. I have an inflatable mattress that is made of two sides. I can sleep on one, or lay the other one next to it and zip them together for a queen size mattress. If its cold, I put them on top of each other and still have a single width but I get up higher. It is bulky and heavy but it reduces the amount of spousal dis-harmony at night. I'd like to get some foam roll outs too for fast bug out.I'm too old for sleeping on the ground... Sleeping bag on a military cot & pad is a minimum. Not worried about the weight, I'll just make my wife carry it. ;^) Kidding on the wife part.
