I don't know if I'm being dumb but while I really like this mattress for camping because it doesn't deflate or feel cheap, I also cannot figure out how to deflate the thing without pinching the air valve and pushing the air out. I took this camping last month and it was great for sleeping. Very sturdy, didn't deflate overnight or squeak/make noises when I moved around and was pretty easy to inflate with my hand pump, overall a great mattress. But when it came time to pack up, I was sweating and stressing because it literally took me 15 minutes of squeezing and pinching to get all the air out. Maybe I'm missing something or just need to master the deflation technique. Otherwise, I really like this mattress and I like that it rolls up pretty well so it's not super heavy or bulky to pack away when you're not using it.
