I bought 3 of these to use temporarily and for extra sleeping arrangements for my vacation house. We still have more work to do and I didn't want to sleep on air mattresses anymore till work is completed. I also got some folding bed frames to put them on so we don't have to lay on the floor until I decide how to set up the rooms. Luckily I have some pretty large storage areas to put them in when not in use later as they are bulky. I haven't used them yet but I did unpackage one to try it out. It was very comfortable and cool. The cover seems well made,nicer than I expected, and the foam is in seperate zippered sections. I think this will help maintain shape. Very well put together. I only gave it 4 stars because they are pretty expensive for what they are, but I think they are better than air mattresses and you don't have to worry about them popping.
