I purchased a 5" thick full size mattress, cut it, then sewed up some temporary covers so one can at least slide around on them. I'll pick upholstery material and make covers when I get farther along. The backrest on the left can and will be used to fill the gap at the doorway, making a 69.5" long bed. Shelves in the nose hold all the bedding for two and again, the wifes little dog sleeps on the fwd lower shelf.
