Rather than settle for RV or residential furniture, I made the frame and had an upholstery shop make the cushions for TWO couches in my coach. This gave me storage underneath, utilized every single inch of space, had commercial grade covers made that unzipped to be washed on a regular basis, included cup holders and outlets in the arms, and the total cost was less than a single RV couch.
I did order new Captains seats that were custom made with special foam for comfort. These came from Shop4seats when they were operating under a different name.
