This is exactly what we needed for that one extra bed tucked away.  My husband is handier than most but he does fuss over my ordering items that have to be put together and he had this done in 45 minutes.  Great Grandma slept on it that night and for the rest of Thanksgiving week without a problem.  It folded right back up and we got our office back when she left. Not obtrusive when folded up and the mattress is super comfortable.
