we have the areobed air mattress in our sofa sleeper. Been used for probably 45 nights in the last 2 years by DD and SIL and guests w/o any problems. What I did notice is that we are VERY carefull in how we put the mattress back when the couch is folded. From observations, it looks like if one isn't careful there are places that could end up rubbing or puncturing the mattress when folded. the mattress is slightly longer than the bed, so when folded up the top portion best fits if it hangs down behind the sofa.

Our Eagle came with an air mattress with a built in pump for the sofa. I have used it to accomodate my mother on several occasions and it seems to hold air and be very comfortable. If something does go wrong with it I think we will just get a good quality air mattress from WM and use it as long as it works. Don't want something too comfortable...guests may overstay their welcome. ;-)
