A sofa bed is a piece of furniture that can be used for both sofa and bed. Modern living room layout is simple and versatile, and multi-functional furniture is becoming more and more popular choice. The sofa bed is one of them. In a small family room, a sofa bed is necessary to meet the occasional visitor's needs.
Normally, the sofa bed can be placed in the living room or study room to function as a seat; on the evening of the guest's arrival, the sofa bed is unfolded and the bedding is a bed. In the ordinary three-bedroom and two-bedroom units, the sofa bed can also be used outside the guest bed to help the owner to cope with occasional visits from multiple guests. Choosing a suitable sofa bed is a matter of course. The sofa bed should satisfy both the sitting and lying functions. It must be durable and beautiful, and its materials and processes should be guaranteed.
