Production technology of sofa independent spring bag

Independent pocket spring sofas are generally used in the sitting pockets of sofas such as Pijiabu, that is, the sitting pockets are supported by pocket springs arranged side by side, and a layer of sponge is generally attached to them, so that each pocket spring is evenly stressed and the sitting feeling will be more comfortable. The principle is similar to the popular independent pocket spring mattress. Home sofas do not use independent pocket springs. Because of the high cost and complicated manufacturing process of independent pocket springs, most of them are supported by high elastic bandages now. If the sofa design needs it, it is supported in the form of a cross with snake springs and high-elastic bandages in the wooden frame, and then packaging accessories such as sea surface, cloud silk, non-woven fabric and cloth are designed on it. The backrest is simpler, a good sofa is supported by a high elastic bandage, and a general sofa is near the sea.

A few high-grade full leather sofas use independent pocket springs, which are exported to the domestic market. In terms of export products, many foreign countries still require more traditional sofa production technology, so the sales volume of this kind of sofa in China is not very large, the price is high, and the sofa cushion is not very flat (with bulging effect), so the sofas sold in China generally do not use independent bagged springs to produce sofas.
