Before the sofa starts to be produced, the master with rich experience needs to draw a good plate. Without a good template, it is impossible to make a good sofa. Because each joint requires sophisticated calculations, the way it is made worse is not a little bit of a gap.
After the plate is set up, the frame of the sofa is officially made. The current sofa frame is mainly divided into two materials: solid wood and composite panels. The frame of the sofa is similar to the human skeleton in Xiao Bian's view, supporting the entire sofa. The firmness of the sofa frame structure and the rationality of the design angle will affect the quality and function of the sofa.

Springs generally use serpentine springs (also known as S-shaped springs) to increase the capacity of the sofa, and then use special spring clips to reduce noise. The spring mounting must be firm and cannot be changed when pressed hard. The quantity depends on the specific needs.
5. Mesh cloth
The cushion area is covered with breathable mesh cloth, which can effectively prevent moisture and increase the life of the sofa.
