The Serta Harper is a twin-size sofa bed that converts from a two-seat sofa into a sleeper, with a sloped back and woven fabric upholstery. It has built-in USB power ports for charging phones and tablets, and Serta says assembly is easy. The 450-pound weight limit is high for a twin sleeper, which makes it a practical pick for a guest room, studio or small apartment. Against other twin sofa beds, its charging ports and higher weight rating are the main advantages; the trade-off is a compact 53.3-inch width that seats two closely and sleeps one.
