I was waiting to see if anyone got back to you.
We have a Fuzion with the air bed. Part of the air bed rests on the sofa with the cushions removed, and the rest of it sits on the floor like a regular air bed. It has the built-in pump and inflates and deflates pretty easily. It will lose a little air overnight, but hit the button and it takes just a minute to bump the air pressure back up.
The people that have used it have praised it unanimously as being ten times better than one of those jack knife sofas. And pretty comfortable in its own right.
