Balance is also very important when arranging furniture. You should not have all the heavy furniture on one side of the room. For example, if you have a large wall unit on one wall, you should have another large piece of furniture on the other side of the room.
Lighting, Artwork and Accessories
Besides the basic furniture, you will want to have lighting, artwork and accessories to warm up the space. For your lighting requirements, it is best to have a mix of overhead, ambient and task lighting. Use a mix of overhead lighting, table lamps, floor lamps, and scones. Artwork is important, however, it should not fill every wall space. It should be hung at eye level or lower and not be too far above the furniture. A large piece should be placed above the sofa approximately 2/3 the size of the sofa. Accessories add interest to a room. It is best that you have a few larger items, versus many small pieces.
Also you can add throw pillows as great decorative accents to your sofas and chairs, but don't use so many that you need to remove the pillows to sit down.
Area rugs can define the conversation area. The furniture should be sitting on top of the rug and ideally there should be approximately 10" to 20" of bare floor between the edges of the area rug and the walls of the room.
