The "sofa" that foreigners call is generally referred to as a three-person seat, that is, a couch. Currently generally referred to as a cushioned chair with a backrest and armrests designed to accommodate two or more people sitting or lying alone. Therefore, China's furniture manufacturing industry habitually extends the "sofa" to all soft seats.
The narrow definition of a sofa refers to a low seat with a spring cushion; the broad definition refers to a seat or a horizontal appliance with a cushion or soft contact surface, such as a sofa stool, a sofa chair, a sofa bed, and the like. The core of the sofa is a cushioned structure that has been developed from springs to be filled with elastic plant fibers, animal hair, foam rubber and foam, and woven with rattan skin and rope. It is made of inflated or filled with water, and can also be made by compounding a spring with an elastic filler. The contact area between the sofa and the human body has a soft contact surface, so the sofa is collectively referred to as soft furniture.
The average single sofa size is: length: 800-950mm, depth: 850-900mm; seat height: 350-420mm; back height: 700-900mm. European-style furniture is generally more atmospheric, taking up a lot of space, suitable for large families. The comfort of a single sofa is very important, and the armrests of a single sofa are generally 560-600mm high. The sofa should be soft and moderate, and the sofa that is too hard or too soft will sit back and back.
The size of a typical double sofa is: length: 1260-1500mm; depth: 800-900mm. The height of the seat of the sofa is generally 400mm, which is almost flat with the living room coffee table, so that the seat is more scientific and reasonable, and it looks more spacious with the living room furniture.
The average three-seat sofa is of the length: 1750-1960mm, depth: 800-900mm. If your living room is large, it is recommended to buy a European-style sofa. The European-style sofa design is more atmospheric, so it takes up a lot of space. If you are a small-sized family, you should be cautious when choosing European furniture. Pay attention to the size of the sofa before you can master the size of the living room layout.
