This tri-fold is going to be perfect for my upcoming guests.  It's not the narrowest tri-fold avilable but is narrow enough to act as a stool in the room when folded up and not take up a lot of space.  I was pleasantly surprised that it came in a zipped plastic bag in case I want to store it away in the garage.  I can't speak yet to its sleep comfort since no one has slept on it yet.  When I briefly laid down on it to test it it was firm and I didn't just sink to the floor.
