>>2828855not common, but I actually ended up doing this by accident and have been sleeping on it every night for like 2-3 years now. granted, it's a pricey one and I'm only 140lbs so keep that in mind. NEMO Roamer... got it on a great sale during christmas time one year for camping, set it up to try for a couple of nights in the house before taking it camping... it never left the house after. the most shocking thing to me was that it hasn't seemed to lose ANY air over the years. not even in the winter and I keep it pretty chilly inside. my cat even got it's claw hung in it once and I was sure it was doomed, but never lost any air. it's basically a memory foam/air chamber design from my understanding. I'm the type of person that usually tosses and turns every hour or so in my sleep. stomach, side, back, everything. I was shocked when I first tried it for the first couple of nights because I literally didn't even wake up at all during the night. I awoke in the morning the same way I fell asleep, which I can't remember doing since I was a kid. it's pretty damn amazing, and despite getting it heavily discounted, I'd buy another one at msrp if I had to without any hesitation. they make a XL size one, but even the standard is longer than most mattresses which is good for tall people. I'm 6ft and don't hang off. can't say someone else will have the same results, but I don't think I've ever been as surprised with anything I've bought.
