One small issue that I ran into after narrowing the floor was that the front couch cushions wouldn't fit anymore. They were 6" too wide so I pulled some staples back and peeled the fabric back and cut one cushion down to the appropriate size. it makes for a pretty short couch. but it will make a great sleeping area for my youngest son.
