Not only that, but in my experience they usually kinda suck. They are super thin, and with age they start to take quite a while to inflate. For the tiny amount of air in the pad, you could fill it with your lungs in a few breaths at most. I've been happier with non-foam inflatables that roll up much more compactly, and blow up to be two or three times thicker.
Therm-a-rest stood my test. How often did you use it, or rather, how did you store it? I've put mine to the side of the some wall, inflated, not rolled up. Used heavily every few weeks or months for a few days from about 2008 to 2014, after that only about two times a year for a few days. Can't complain.
Ok, now I'm sad! I hope the one I bought recently is a bit better than the old ones you guys tried, we'll see. I've only used it a handful of times so far.
