Thanks so much Katie. You were the one I had in mind that might have the photos. I thought I had seen them before, but now that it is relevant to my trip, I couldn't remember what it looked like. Thanks for the tip about the egg crate, I'll keep it in mind.
Diane, thanks for comfort comments. I hope SIL will be comfortable on it. When we stayed at VWL, she had already slept on it 3 or 4 days. I sat down on it, and told her I was so sorry it was so uncomfortable. I didn't realize how bad it was until our trip was half over. She said she had learned where the bars were and was trying to stay away from them!

Poor thing! At least she was sleeping in it by herself, and could kind of lay diagonal on it. When we had a BCV stay last May, my DD's started complaining about how uncomfortable the pullout was there. They are only 8 and 4 so I figured it had to be bad. I laid on it, and figured out that the matress was upside down, so the springs were sticking right through. I had to unmake the bed , flip the mattress over, and remake the bed. I'm just glad that I had read about this happening to someone else on this board, or I wouldn't have ever thought about, and my poor kids would have been complaining all week.
