Map out the layout you have in mind for the living area. Measure the room dimensions and the sizes of each piece of furniture. Draw them on a piece of graph paper according to the measurements. This plan enables you to move the furniture pieces around on the paper rather than lifting heavy furniture multiple times. Include windows, doors, architectural features and hallways on the paper.
Start the layout by placing the sectional opposite the main feature in the room. This is often the TV, a bay window, piano or a fireplace. Setting the sectional opposite the focal point enables people to watch TV or view a crackling fire with ease. Position the sectional so that it doesn't block air or heating vents, doors, hallways or juts out into the walkway through the room.
Add the remaining furniture to the layout so that all pieces angle toward the focal point. This forms a cozy conversation area. Allow at least 18 inches of space or more in the areas that people use to walk through the room. This prevents someone from bumping into furniture jutting in the pathway.
Place a coffee table or attractive area rug in front of the sectional sofa. This adds balance and continuity to the large piece.
