my son and his wife slept on ours and he said they met in the bottom of the middle of the bed. they made a second bed in the middle of the night on the kitchen table. slept much better. I have wondered the same thing and my son said no matter what we put on it or try to do it will still be a blow up bed and you will meet in the middle.
This is our experience as well. Nice to hear someone confirm it.
We tried putting a 2 inch foam on top of the air mattress. It helped the heat issue, but not anything else.
We threw the same 2 inch foam on the floor and it made a very good bed. 2 problems with using a piece of 2 inch foam. 1) where to store it. 2) The sofas are the way of where we would like to use them.
