Long, narrow rooms are the bane of furniture arranging. But there is a way to play up this awkward space to your advantage: Divide the room into zones. Arrange the conversation area in one zone, and place a desk along the back of the sofa to create a work zone, or place a small table and chairs in the area behind the sofa for doing homework or playing games. You can also place two small chairs and a side table along the back of the sofa for a smaller secondary seating area.
