Decide the focal point of your room. This could be a window, a piece of artwork, or another piece of furniture such as a bookcase or entertainment cabinet. Place your focal point directly across from an entry or exit point of your room; or put the focal point on the wall adjacent to the doorway, so that people actually have to come into the room to see it.
Place the longest portion of the L-shaped sectional on the opposite wall from the focal point, facing the focal wall. Allow the short portion of the sectional to rest on the perpendicular wall.
Place the second couch in front of the focal point, with the back of the couch facing the focal wall. Allow the L-shaped sectional and the second couch to form the shape of an open square. This facilitates face-to-face conversation between people sitting on the couches and lets individuals with their back to the focal point appreciate other aspects of the room.
Don't let the back of either couch face any doorways in the room; according to Design-Distinctions.com. Arrange your furniture so that it welcomes you into the room.
Place a coffee table between the two couches to keep magazines, snacks, drinks and remote controls within arm's length of anyone seated on either couch.
Place an end table next to the short section of the L-shaped sectional, and an end table next to the opposite-facing couch, if you have the room. This provides a place for additional books and magazines, as well as lamps and candles.
Clear a path between the couches and tables for room traffic and keep all entryways and exits clear. If the short section of the L-shaped sectional has a chaise or recliner attached, make sure there is nothing blocking someone sitting there from stretching out.
