The sofa is mainly composed of three parts: frame, filler and fabric (these three parts can be divided into several small parts). The frame constitutes the main structure and basic shape of the sofa, which mainly meets the shape requirements and strength requirements. The types of frames are solid wood frame, sheet frame, solid wood + sheet frame, glass frame, iron frame, plastic frame, stone frame, rattan and bamboo frame. The filling material plays a decisive role in the comfort of the sofa. The traditional fillers are brown silk and springs, and now commonly used are foam plastics, sponges, and synthetic materials with various functions. The texture and color of the fabric determine the taste of the sofa.
