When creating a design for your living room, keep in mind how the living room will be used. A living room with surround sound, for example, will require a particular design in order to get the full effect of that sound. Whether there is surround sound or no sound, a living room should be a room that creates a relaxing atmosphere in which one can read quietly, visit with friends, or any number of things in a comfortable manner.
Consideration of furniture is important. A casual living room will not have stiff furniture that provides no comfort when sitting. That type of furniture should be reserved for waiting rooms at a doctor's office or school rooms. A comfortable living room's couches and chairs will be made out of soft, perhaps plush fabrics that invite a person to relax on them. Their comfort will be further enhanced by soft, plush pillows of the same fabric. Some will even add pillows that contrast with the colors of the couches or chairs. This furniture is something that can be relaxed and socialized on in complete comfort.
Flooring is another important consideration for this room. Hardwood floors are very popular right now, yet they do not have to be the only choice. Hardwood is pretty and easy to clean, yet it's cold. If your home is often cold and you're looking for economical ways to keep it warmer, carpeting is one way to do that. Carpeting will hold the heat in the room better than hardwood flooring which will make the room warmer longer.
This will in turn use your furnace less and your money will be saved. However, if you have allergies to dust or other airborne particles, carpeting may not be a good choice. No matter how often you vacuum, it can be very difficult to get those allergens out of the air. For this type of person, a hardwood floor would probably be the better choice because there will be less fibers in the room to hold in those allergens.
