I am positive that a couple of years ago while flicking through teh Sunday Time travel I spotted a airbed that folded up into a sofa. Not the expensive piece of crap that comes up if you google airbed and sofa but a pretty bog standard double airbed (think it was coleman) that made a sofa. It wasn't just a fold in half thing, it was a bit more jigsaw like. Anyway I always thought it would be good idea and now I have the dcs, I have a dh who is just about convinced about camping and I have a family tent donated by may parents so I want one!
