We got our Class C and wanted to add some seating space. We had a local upholsterer make us three new cushions with the same size and cloth materials that are in the dining booth seats. Here is our result. http://kyrvers.posterous.com/customized-dining-booth The back cushion is the full length of the booth and fits snugly into the side cushions. We had some pillows hiding it a bit in the picture, but it works just like we thought it would. It's very comfortable and opened up a lot of seating/laying around space.
