Try the furnishings arrangement first and see if you think ti will work for the room. Then if you think it will work, consider a way to fish the cable over to the right location. If you have an attic or a basement the cable can usually be easily run to the new location. Sometimes the cable can run below the area rug to the right location or secured to the baseboard. Be inventive! There are other options if you are willing to purchase new seating. I just assumed you were trying to use your existing furniture.

A picture or two would help greatly, if you can post some.

Start with a good-sized high-contrast rug like those suggested already. Once you see how that looks, then move on to your other ideas--desk, bar, etc. Grover's idea for a sofa table displaying photos or art work is just great because it opens up the window and curtain space. Going forward, Keep in mind that you have all brown flooring--a "fourth wall"--massive brown sofa, big black TV set, brown table in the niche, and brown coffee table. Enough with the brown! Notice how great your curtains look. Add light pillows or pieces with color or other finishes than brown. Good luck!

Hi! The image isn't a picture of the exact room, but is similar. The room does already have carpet, which is similar to the image, but perhaps a bit more of a tan. I still want to add a rug to tie the room together a bit. Appreciate you taking a look!
