The seat of the sofa refers to a cushion part of the sofa, and is usually made of sponge, springs, fabrics or leather and other materials, and the quality and the comfort degree of the seat have great influence on the overall comfort degree of the sofa. The back of the sofa refers to the back portion of the sofa, and is typically composed of sponge, fabric, leather, or other materials, the quality and design of which greatly affects the appearance and comfort of the sofa. The width of the armrests of the sofa varies from sofa to sofa, usually between 20 cm and 40 cm, and generally, the width of the armrests should be capable of supporting arms of a person, so that the person sits on the sofa with a stable supporting point, and thus has a more comfortable rest.

The seat of the sofa, the back of the sofa and the armrests of the sofa are generally fixed in volume, and during the transportation process, only the seat, the back, the armrests and other components are stacked on each other, so that the reduced space is still not obvious in general, and the problem of transportation exists.
