The most common piece of furniture in our homes is the sofa. After a tiring and busy day, when we return home, we often like to relax on our comfortable sofa.

Besides the bed, the sofa is probably the furniture we interact with the most daily. Have you ever wondered how exactly a sofa is made?

To start the production of a sofa, a skilled craftsman must first draw an accurate template, as the success of making a quality sofa relies on having a good sample. The precision of each joint is crucial, as even a small deviation can affect the overall appearance. Once the template is ready, the actual construction of the sofa frame begins. Sofa frames are typically made from two main materials: solid wood or composite board.

The frame serves as the backbone of the sofa, and its strength and design angles significantly impact the quality and functionality of the sofa.

For a solid wood frame, the production process involves several key steps:

1. Drying Wood: Wood, containing moisture, is dried to maintain a moisture content of around 12%, reducing the risk of deformation, rot, and insect infestation.

2. Cutting: Using the template, parts like the backrest and armrests are cut and then undergo processes such as sanding, wind shearing, and trimming.

3. Reinforcement: Joints are precisely positioned, and wooden triangles are added for reinforcement. Nails or screws are used, and white glue is applied to secure the joints.

4. Priming: Springs and bandages are added, with serpentine springs increasing bearing capacity. The back frame may use rubber bands or black belts made from discarded tires.

5. Mesh: The cushion area is covered with a sturdy and breathable mesh to prevent moisture and enhance the sofa's lifespan.

The next stage involves the sofa filling, which includes sponge, down, and artificial cotton. Different densities of sponge (high, medium, and low) affect how the sofa feels and its overall lifespan. The filling is cut to match the sofa's shape and wrapped around the frame. Following this, the outer cover is cut and sewn. Leather boards are used for each side of the sofa, and great care is taken to avoid substandard leather. The skins are cut, and the cushions, armrests, and backrests are sorted and packed for efficient sewing.

The sewing process is crucial for the sofa's appearance and craftsmanship. Each piece of leather is stitched together, and the pressing thread ensures symmetry, clarity, and uniformity.

Lastly, the sofa is covered with sewn leather or fabric. Fabric sofas may require additional hardware like zippers. After completing these processes, a comfortable and finished sofa is ready for use.
