Sofa structure
At present, the sofa on the market can be divided into three parts in structure and technology: a, solid wood structure; B, plate and wood structure; C, all-steel welded structure. When choosing, you should pay attention to shaking the sofa to check the stability of the structure, open the zipper at the bottom and take a deep breath to smell whether it makes sense, and sit under gravity to feel the impulse response.
Solid wood structure
The sofa with real solid wood structure is quite expensive, so it is necessary to ask about the variety of solid wood and the technical means of the manufacturer. Sofas of this structure are rare.
Plate-wood structure
Using cheap wood squares as beams and vertical supports, combined with multi-layer composite plates, the structural skeleton is made of nails. This structure has the advantages of low material cost, simple manufacturing, convenient molding and high manufacturing efficiency, and is a widely used process structure at present. Disadvantages: the multi-layer composite board has high formaldehyde content, which is easy to cause pollution and emits a lot of odor, and its firmness is generally easy to deform when wet, and its service life is short.
All-steel welded structure
Ordinary standard square steel pipe is welded and formed under standard fixture, and it has rusted. This process is difficult to form, with long working hours and high technical requirements. Advantages: good structural stability, high strength, good environmental protection and long service life. At present, most European sofas adopt this structure, which is the future development direction of domestic sofas. Only a few brands in Beijing market have this structure, which is an ideal product for consumers to choose.
