To arrange furniture in a long, tunnel-like room, make a sketch to help analyze traffic patterns and arrive at furniture placement. Section off parts of the room into nooks that can be used for a breakfast area or other things.

When it came to placing the rest of the furniture, it may be necessary to situate the sofa along the room's long wall. To do otherwise would mean transecting the room, and since the purpose of a sunroom is to provide a place for family members to sit and enjoy one another's company, it's necessary to create an inviting conversation area.

To block out overwhelming sunlight, place a paper-and-bamboo screen on one window to cut and diffuse the light.
