Sofas are typically the largest piece of furniture in your living room or den, which inherently makes them the focal point. If your hang-out area is on the small side, the wall may be the only place that your sofa actually fits. But if you have some extra space to play with, there are other options that will create more visual interest. Putting your sofa on a diagonal makes your room seem a little larger, plus it gives you extra storage in the corner behind it. You can also pull your sofa out from the wall to allow traffic to move behind it. Just be sure to leave a walkway of about 3 feet.
