It is possible to use a conventional rectangular table with a sectional, although there are a couple of considerations to keep in mind. Those who use the sectional need to be able to walk behind the length of the table to make use of all seating space. Leave approximately 18 inches open between the table and the front of the sectional. Rectangular coffee tables sometimes reach lengths of over 50 inches, and the table should not be as long as the seating area behind it.
The curved shape of an oval table allows easier movement around it, compared to a rectangular table. Oval coffee tables average between 39 and 52 inches long, so find one that does not completely block the seating area of your sectional. Traditional and contemporary styles are available that can coordinate with the look of your sectional. You may prefer to add one or two end tables if your space allows.
A round table looks stylish when nestled in the corner of an L-shaped sectional. However, it provides the best tabletop access only to those who are seated closest to the corner. With a round table, you may find that end tables are more important than with other shapes of coffee tables. Round tables are available in many sizes, but if you select a larger table to better accommodate those seated at your sectional, it will protrude farther into the room.
Like a round coffee table, a square shape works well with an L-shaped sectional. However, a square table should not be so large that it extends beyond the short end of your sectional. Select a size accordingly, allowing 12 inches or more of space to move about between the table and the front of the sectional. Some seating on the longer end of your sectional will be without a table surface to use, so provide an end table on that end.
Coffee tables are available that are long and narrow like a bench and can be placed along the front of the longer section of an L-shaped sectional. Also, a actual bench without a back can often serve as a coffee table. If you choose a bench shape, select a size that allows plenty of walking space on all three sides that face the sectional.
A good solution is a group or series of small coffee tables, known as bunching tables, that are approximately 16 to 24 inches wide. Line up a set of two or three square or round shapes along the longer section of your L-shaped sectional, leaving as much or as little spacing as you like between them. Or, cluster three of them in a triangle or asymmetrical shape and place them in the corner.
