mid century couch? need info

I found this couch in a little furniture store that sells old furniture. I loved it on site. I think however, that it is part of a sectional. The round footstool is original to the piece but the square one is not. It has been recovered professionally. What I would like to know is if anyone can tell me anything about this and where I might find pieces to go with it. Email to rsimonson@cableone.net
