Out of the blue, we have guests coming for T'Giving. I need to come up with a bed for an older couple, one of whom is overweight. We have a good quality air mattress but am wondering if there is some sort of frame that it could be placed on so that it is more "bed-like" and would support their weight. We slept on it as is for several months but it bounces around a lot and sheets pop off of it so not exactly welcoming for guests. I could buy an inexpensive platform and mattress but don't anticipate a horde of visitors in the future and the room is actually DH's man cave so a permanent bed would eat up his space. And I have two weeks to figure this out. Any ideas appreciated!!
