A couple of years ago I had one of the one man mattress' s, it was made for sleepin on not one of them pool things. I' m not a real big guy, I' m about 6' 2" 210lbs., but I rolled over in the middle of a very cold night and I hear POP!!! The thing blew a huge hole out the side and I was on the ground in less than a second. I got up in the cold to monkey around with it and the hole was too big for the patch and I spent not 1 night but 3 on the cold hard ground. That translated into sore muscles in the morning and not good rest. Made for a real tough hunt. I like the self inflating pads, you have to try pretty hard to put a hole in one of those things. They' re not real thick though (mines 2 inches) so a thick foam pad may be better for some of you old timers.
