I have a murphy bed in my sewing room which is very nice. But I also have a queen size frame for our aero bed. I found it for camping, because when I turned 55 I found I could no longer sleep and dress on the ground while camping and my niece had one that she used for guests. It is put away in the camping equipment so I don't know the name. It collapses into an area of 18 inches high, and then 12 inches square. It holds both my husband and I (we are not small) with the air mattress and 2 sleeping bags. So you can set it up just when you need it.
