I would probably move the loveset under the window and the chairs where the loveseat was it will look mor einviting than the back of the loveseat but that said why such dark furniture in this space there are 100s of color for letaher furniture why dark brown. A nice creamy white or taupe would be a much better choice . Do not add a sectional to this space at all in fact I would probably just do a sofa and the 2 chairs to see how that works. An interesting rug with some color some drapes on the window , a shallow cabinet below the T.V the chairs can then be put one on either side of the sofa to really make that space feel much more open

Thank you very much for your ideas. The furniture is actually being moved to the finished basement so I am pretty open to anything in terms of replacing the sofa and loveseat. Should I drop the idea of a loveseat and just go w/a sofa??? Also in the corner by the lamp, I considered a chair/ottoman combination. Would that work? The rug is actually an old comforter that I put down to keep the furniture from moving when you sit on it. LOL. I'm concerned about stains and such on lighter furniture that's why I've been hesistant to go too much lighter. I like the idea of an interesting rug but I'm worried about something clashing with the pattern on the chairs.

The lighting makes the furniture look really dark but in reality it is about 2-3 shades lighter than espresso.
