2, fabric sofa to see fabric: fabric depends on whether the fabric is closely attached to the internal filler, whether it is flat and crisp, especially the joint between the two handrails and the seat back should be naturally wrinkle-free. If it is a circular or semi-circular handrail, it depends on whether the radian is smooth, plump and beautiful.
3. Interior quality of sofa: At present, the top-grade sofa seats, back and bottom surfaces mostly adopt the cross-netted structure of nylon belts and snake springs, on which high-elastic foam, rubber-sprayed cotton and light foam are laminated. This kind of cushion has good elasticity and comfortable sitting feeling. Mid-range sofas are mostly based on bonded fiberboard and back, with medium density foam and glue-sprayed cotton laminated on them. This kind of cushion feels hard and has poor resilience.

Sofa maintenance method:
1. Wipe with nursing agent: For the newly bought leather sofa, first wet the towel with clear water, wring it out and wipe off the dust and dirt on the sofa surface, and then gently wipe the sofa surface with nursing agent.
2, soft cloth wipe: you can gently wipe the sofa with distilled water and soft cloth every week. If it is a leather sofa, you can use colorless shoe wax or leather grease and maintain it once a month. About 2-3 months, you can clean the sofa with cleaning agent, or use a vacuum cleaner to suck out the dust on the sofa surface.
3. Pat: After sitting for a long time, gently pat the edge of the seat and sofa to restore the original state and reduce the slight depression of mechanical fatigue caused by concentrated sitting force. In addition, the sofa should be placed away from heat dissipation objects, such as not in direct sunlight.
