This will help balance the visual weight of the sofa and add interest to the floor. You don't want all heavy wood tones down low and light and bright colours above, so use the rug to bridge that gap.
A heavy leather couch just won't work with a light and airy glass coffee table.
Not only does it provide added storage, but a sofa table will also break up the large dark void that is the back of the couch.
Light and watery colours that occur in nature (think sky and ocean) complement browns best. Other natural shades, such as sandy creams and rust tones (see above), also work well.
Keep the space light and bright, but warm. But don't go too far: Stark whites can actually read as harsh against the warm natural tones of the rest of the space.
