Ohhh boy...<br>I currently have a Select Comfort (and love it!). However, since it needs electricity to inflate/deflate, I figured I would switch it for a regular camping air mattress with a portable pump, when I went mobile. After all, a SC is really just a glorified air mattress, right? But now I dunno if a regular air mattress would be good after all...<br><br>though I've heard to fix the thing about being cold at night, is to put a closed cell (I think that's the cell) foam mat under the mattress, and that keeps the heat from leaking out into the ground.<br>Last time I went camping I had (from bottom to top): foam pad, regular sleeping bag, hunting sleeping bag (that I slept in), wool blanket, fleece blanket. Despite there being frost on the ground in the morning, I actually had to take the blankets off in the middle of the night because I was so warm! (I also was wearing wool socks and a pilot hat with the ear flaps tied closed under my chin).<br>
