There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

I have two nine feets sofa.which size carpet should I prefer.

Hello, can you please share the dimensions of the carpet area and know where it is located in the house. I'll see what I can do but please note that I'm just giving options. I am not a professional but I wish to be one. It is completely up to you to decide.

Nice
