Whilst maintaining themes throughout your space make sure that you do not add too many and also that there are not too many dominant pieces in any given space. By their very nature the quality of a natural wood finish can be very alluring and eye-catching so avoid using tons of this material everywhere.
Having rugs in your living room will make it warm and cozy. Without any depth or color all you see is bare floors and furniture. Rugs make the room look elegant with a touch of essence. No longer will you have to go into a drab looking room that doesn't have any color or sense of style.
One of the common areas to place the pieces is underneath the coffee table and in front of the couch. If you do use this scenario all four table legs should fit on the rug and not on the ends. It should have enough length that there will be room on all four ends. It looks very tacky to have table legs placed at the end of all four corners.
