ALPS Mountaineering Featherlite Air Pad

Comfortable for back or side sleeping, nice and light, super easy to inflate, and no headaches from blowing into the valve! What more can you ask for?

This mattress is light (under 21oz), comfortable (3.5" thickness!), and inflates easily with the built-in CPR-style pump (65-75sec to inflate). I've slept a couple dozen nights on this, and I wouldn't go afield without it in the warmer months.

It's no good for cold weather due to a lack of insulation, but for warmer temps, it's the best camp mattress I've ever found. It's so good I even take it when I chaperone youth trips with my church so I can be assured of having a bed (because sometimes the youth leader doesn't plan 100% on the numbers...). I've slept on my side and my back on this mattress with zero complaints.

About the only possible complaints are that this can be noisy at first, if you're not used to it. I don't notice much, but some folks complain about noise for a lot of different mattresses. It also can get a puncture pretty easily, but those are readily patched with a little clear nail polish, once the pinhole is found.

Now, this isn't a fragile mattress. I've only had to patch one of the two I have, and only once, over the several years of owning them. But by comparison, I've never had to patch either of my self-inflating foam pads.
