The furniture needs to be rearranged. Consider putting the couch centered on the wall with the coffee table centered in front of the couch. Then, put the two side chairs together, facing the coffee table and the couch. This will make for a good conversation area.
Accessorizing the room will do wonders for your décor. Simply go shopping for wall art, coffee table décor and some colorful pillows. You may also elect to put a small rug under the coffee table. Because your walls and woodwork and furniture are neutral, you can mix just about any color you like in with the accessories.
If you are going to put a rug down, begin there as the patterns or colors I the rug can inspire other selections to match it. You may want just a solid rug and that is okay, too. But, do add color, texture and pattern into the room with decorative pillows and some art work.
