Nice New Couch

We renovated our sunroom just before Christmas. Before it was a large, rectangule shaped room with 15 windows and a patio door. We turned half of the room into our bedroom, replaced the windows and patio door and installed new flooring. Now its our playroom/family room that houses all our kid's toys, a small bar area and a record player. It's always been a working progress, and I know I'll be spending many more months just getting the room right. I hate to admit it, I still don't have curtains on the windows.
But what I do have now, is a nice new couch! The only seating arrangements we had was an old computer chair in the corner and kid-sized stools. I wanted something we could sit on to read books, relax why our kids played in there, and a piece of furniture that would take away some of the emptiness the room had. Of course I had an idea of what I wanted, either a big comfy couch, or 2 large reading chairs. I had been searching around online a bit for some ideas, when all of a sudden a fellow facebook friend posted a FREE couch to give away! It's straight out of the 1970's but it's been cleaned and well taken care of. For a stay at home mother of 4, you take what you can get! It wasn't the dream couch I had been imagining about for that room, but it was bright, funky and in great condition. I figured I would just roll with it.
This gorgeous antique doesn't really match our wall colour at all, but that's something we can change. A gallon of paint is cheaper than a new couch. It does, however, match my toy baskets, pillows and wall decor.
 I'm just happy we finally have a little life in that room, and somewhere to sit.

Next is to find an area rug and maybe a lamp to match. I'm choosing a solid colour rug so it doesn't clash with the pattern on the couch. Should it be red to match the couch, blue to match the walls, or a neutral colour like beige? Here are some ideas I found. 

What do you think?
