Couches by day and beds by evening, daybeds are dynamic pieces of furniture. They often have only one long cushion and are backless, but by positioning them against a wall and piling up plush pillows, you can get back support. Some convert into a more spacious sleeper with a trundle mattress. Their dual functionality makes them a favorite choice for family rooms, living rooms and guest rooms. If your overnight guests will be sleeping on it, be sure to provide extra sheets, blankets and pillows as well.Settee: A settee is an elongated chair that’s slightly bigger than a loveseat and usually fits two people. Typically, the height of its back is higher than that of a traditional sofa, and it sits in a more upright position. Settees aren’t just for the living room—they give dining rooms, entryways and master bedrooms an upscale look.
