jimmy benson, as you can see, views vary on neo air. I can tell you that I will happily sell you mine for $85, good condition, used I think a total of 10 days or less, that's the old style yellow one. Neoair is the first mattress that made me actually long for a 3/8" closed cell sleeping pad, first time in decades anything made me think any positive thoughts about those uncomfortable closed cell foam pads, but neoair did the trick, there I was, every night, longing for anything that wasn't a neoair. Tried all the inflation levels as people recommended, but finally realized the r stuff is just totally an illusion, if you have to let x percent of the air out so that you don't feel like you're bouncing off it, then it's not creating that much air space. I gave it a one nighter then a 5 day trip, when I got home, I bought myself a prolite regular to go with my prolite short, and decided that's just fine. Trick with prolites, and I think this only works if you are reasonably light, is to slightly inflate them with a few breaths after they self inflate, then I get no ground contact, but obviously once you go over x pounds of body weight, it's going to push down too hard and you'll hit the ground. I don't. I also put a 1/8 ensolite pad under it.
I believe you could learn something by watching how people who like neoair sleep, and how much they weigh, that's my guess to figuring out why some like it and some don't. Blowing it up, by the way, is not fun, but isn't that hard either, you just pause, take a deep breath, then exhale slowly, repeat until done with a breathing break between each inflation. I'll take the prolite any day of the week.
When I got home from the 5 day trip, I talked to a non backpacking friend, and he laughed, and said, yeah, air mattresses suck, don't they? As in only air that is, no foam or feathers or whatever. So it's not a secret, and neoair isn't much different from any other (non foam filled) air mattress, if you can sleep on them, you will probably like the neo air, personally I've never seen an air mattress I liked that wasn't foam filled like the thermarest prolites and their older models, green, orange, whatever, all far more comfortable than the neoair, and all of which were and are dreams to sleep on compared to anything else for me.
As a side sleeper, I can safely say that neoair is the worst mattress I've ever used, and the only air mattress that made me long for the old closed cell foam pad, which is saying a lot. Just as others here can safely say it's the best.
