Let me preface this by saying I only have the Neoair Xtherm (in large), and I've never been a huge fan of inflatables.
Just got back from a trip where I tried once again to like the Xtherm I bought last year. On paper I love it, on the ground, I hate it. Feels like sleeping on a concrete floor, regardless of how much I inflate or deflate it.
Unfortunately, the days of sleeping on single ridgerest through 3 seasons and adding a torso piece during the fourth are over for me. I wake up bruised and beaten feeling, but it's better than the zilch sleep I'm getting on the Xtherm.
Not bashing the Xtherm, if it works for you I'm envious. Sleep comfort has always been super important for me though, and I'm willing to add a few ounces to get good rest.
For the most part, last few years, the only comfortable sleep I'm getting is in a hammock. That's fine for solos or with my cousin who hangs also, but for trips with the dogs or others, not really an option.
So what alternatives are there? FWIW I'm fine on full-sized cheap-o "guest bed" type air mattresses. They're not the heights of luxury, but I can sleep on them no prob. I dunno if it's the lateral baffle tubes on the Neoairs, the height, what..
Caveat: I'm not and never will be a back sleeper, so a 23"+ wide pad is a must. I'm also still a little angry at the fact that the XTherm is no-where near the stated 25" wide inflated, but that's another story.
What about the Exped options? Anybody find these comfortable but not the Neoairs? How do the R-values the manufacturers give line up with each other?
So far none of the Klymit options look suitable for me, but I'm open to input. Anything I'm missing?
