Try Room and Board.

Curved sofa is a great piece of furniture.The sofa you buy should be chosen based on such factors as how you are going to use it and what sofa style would be best for your room.The internet is a fantastic place to shop. You can find great deals on the web.

Try Lee Industries - the name is goofy but the quality is very good and they have a huge selection of designs.

Baker has a curved sofa. I've been lusting after it for a couple of years. I believe they are very good quality.

I have two of the Lee Industries wedge sofas (C7117-33) "facing each other" in our living room. They are heaven to sit on and each seats 4-5 comfortably!

Look at Palliser or Younger.
