1. The reason for the collapse of the sofa sponge cushion
Many sofa sponge cushions are made of polyurethane foam materials. When foamed under low-temperature conditions, the bubbles are good, uniform in size, high in density, very good in resilience, and durable, but feel hard. On the contrary, poor-quality foam is easy to age and has poor resilience, but it feels softer. After using this foam for a long time, the sofa will sag, which will cause the sofa to collapse.
2. First check the sofa, check the source of the sofa collapse, and prescribe the right medicine according to the cause of the collapse.
3. The collapse of the general sponge cushion depends on the situation. In mild and non-serious cases, it is recommended to turn the sofa cushion regularly, do not sit in the same place for a long time, and avoid letting children jump on the sofa, which will make the sofa sink and deform more seriously. If the sofa cushion has sunk so much that it has seriously affected the sitting feeling and the appearance of the sofa, it is recommended to replace the sofa cushion.
4. If the spring is broken, replace it with a new one. First, fix the spring with small nails on the wooden siding, and then use hemp rope or nylon rope to tie the springs together in the shape of a "meter".
5. When replacing the bandage, the two ends should be nailed to the wooden frame, the end of the band should be folded in three, and the nails should be nailed to cross each other. Nail to the seat frame with 5 cm wide wooden rails along the bottom strap.
6. If the wooden sofa frame is broken, this situation is almost irreversible. At this time, it is recommended to ask a professional furniture repairer or carpenter to repair or directly replace the sofa.
