The craftsmanship of the sponge determines the density of the sponge. At present, the density of domestic sponge can reach but not exceed 45. More than 45 is a resin product, and the cost of resin product is quite expensive, and it is generally used for aircraft seats and luxury car seats.

The quality of the sponge mainly depends on the following points

1. Appearance: In addition to the extra large space, the sponge is free to be empty. The more delicate the sponge in general appearance, the smaller the pores, the better.

2. Hand feel: It can rebound quickly, soft sponge is good, hard sponge is inferior.

3. Temperature: Normal sponges have a little smell, but if the smell is unbearable, use inferior raw materials.

4. Tear strength: A good sponge is not easy to tear, and it is definitely cutting corners if the fingers are not broken at all. In this case, the sofa cushion can be dented by about 10 cm after the human body can sit down. Generally, adding springs to the seat cushion is mainly to increase the resilience of some sofas to achieve the effect of enhancing the service life of the enterprise.

The quality of the sofa sponge directly determines the service life of the sofa.

The craftsmanship of the sponge determines the density of the sponge. At present, the density of domestic sponge can reach but not exceed 45. More than 45 is a resin product, and the cost of resin product is quite expensive, and it is generally used for aircraft seats and luxury car seats. In order to achieve the illusion of high sponge density, some unscrupulous manufacturers artificially add talc powder to increase its density during the production process. However, in the process of processing fossil powder, a large amount of ingredients containing formaldehyde and toluene that are fatal to the human body are used, and the added fossil powder is easy to fall off, which seriously damages the service life and performance of the sponge. Sitting on it, the sofa is very hard, without any elasticity, the sponge is very brittle, and it is easy to fall off when digging by hand.
