Have you ever redone a room?

I was thinking the other day on my long ride home about redesigning a room. There's nothing better than decorating...other than redecorating. What did you use as your springboard for design? There are a few things I've been looking at and can't decide which one to go with. I'm thinking of different rooms like the kitchen,  living room and/or a bedroom. Or I could just add one new, nice element to each room. Hmm, something to think about. But here's some of what I am looking at. I love this theater couch. How awesome would that be in the living room to watch dvd's on. Pop the popcorn and let's go to movies...I mean the living room.
