An apartment size sectional sofa is perfect to fit those odd-sized apartment living rooms that never seem to accommodate a full-sized sofa. Set it up as a large conversation area or pull it apart to make smaller, more intimate spaces. By selecting a compatible style and upholstery, you can match it with modern, shabby chic, or country styles. In fact, any style from the 1920s to present will work, just not the classic styles from eras previous to its invention. You can even set a sectional sofa up as an S curve to accommodate working teams who need to speak with each other.
