We want to buy 2 leather sofas for our open concept kitchen/living room/great/room. The hardwood floors have a dark stain. Should we go with a lighter color rug and dark anthracite/espresso sofas or should we go with off white sofas (what shade of rug do we use then)? Our kitchen cabinets are partially espresso, partially off white. The room is very big, open and bright with large windows.
