dining booth to bed woes

thank you all for your suggestions. I will post a pic as soon as I can. Camper is at the lake!lol I did contact Keystone.. They are aware of the problem from another customer and told me the only solution was to "roll up a quilt to fit the gap". The dealer also contacted Keystone and they told him the cushions have to be turned upside down. Really? Turning them upside down does not change the size. The air mattress is a good idea if I can find one that is not too long. This is the only issue we have with this camper. We love the floor plan. That being said, I still believe Keystone should at least send another cushion "to fill the gap"
