1. The quality of the frame: Shake the sofa front and back, left and right, repeatedly. If there is no looseness or noise, it means the frame is solid. Generally speaking, the rivet and tenon structure should be used in the main frame part of the sofa; wood screws can also be used in other places. If you find that the internal frame is all made of nails, it is best not to buy a sofa with this structure.

2. Look at the wrapping cloth of the fabric sofa: The wrapping cloth depends on whether the fabric tightly covers the internal filling and whether it is flat and stiff. In particular, the transition between the two armrests and the seat and back should be natural and smooth. Shredded pleats. If it is a round or semi-circular handrail, it depends on whether the arc is smooth, plump and beautiful.

3. Sofa internal quality: Nowadays, the bottom surface of the high-end sofa seat and back mostly adopts a nylon belt and snake spring cross-mesh structure, with high-elastic foam, spray-coated cotton and light-weight foam on top. This kind of cushion has good rebound and is comfortable to sit on. Mid-range sofas mostly use glue-laminated fiberboard as the seat and back base, with medium-density foam and spray-coated cotton layered on top. This kind of cushion feels a little harder and has less resilience.
