happyjack2 - Even though our units are similar, they are different. Our 211, with slide, couch does not meet the dinette when jack knifed down. A negative as you have two single beds instead of one large one. A positive as you have a narrow aisle between the two when down. We can use a fitted sheet over each - a tight fit. We bought two single bed foam mattress from Wal-Mart. We then sewed a pillowcase from inexpensive queen sheets. These fold over and rollup easily and then get a strap around them and placed back in the zippered plastic baggie they were bought in. They are very comfy and do not take much time to unroll on the bed and get covered with the fitted sheet and feather quilt.
