In reply to djwilse:
I didn't rate the alpkit offering. I bought the fattest single one they made about 8 years back not as comfy as an air bed and leaked. Currently I'm using a Kampa single air bed and you can tell the difference compared with a cheapy!
Double air beds used to come with separate sections to inflate which makes sense to me!
I used to use a bouldering mat and that was well comfy but it ruined the foam over a few years using it as an bed.
