The sizes that are used for the living room are 4X6 feet and 6X9 feet. Larger living rooms should have more than one piece on the flooring. You can also use smaller ones to place by the fireplace preferably in front. In order to promote unity and harmony to the living room use similar colors and styles.
Functional as well as decorative. A great idea especially when working with a small space is to select items that make great features yet also serve a purpose. For instance chaise lounge chairs are great not only as lounges but they also double as a place to put your feet up and provide extra seating when you are entertaining guests.
Since the rugs in your living room may get a lot of foot traffic a wool rug would be perfect for that. They are soft reliable and durable. They are also low maintenance.
