The Meaning Of The Sofa Sponge

- Apr 15, 2019-

Density is an important indicator of the quality of the sponge. The higher the density of the sponge, the smaller the gap between the sponges inside. For example: 30 density sponge means that the weight of a cubic meter sponge is 30 kg, 40 density sponge means that the weight of a cubic meter sponge is 40 kg, and so on.

The standard for discriminating sponge quality should focus on the effect of rebound or compression with or without deformation. Under normal conditions, the higher the density of the sponge, the higher the hardness, but if super soft additives are added, it will become super soft. Therefore, the hardness and hardness of sponges of the same density are not necessarily the same. The more intuitive feeling of a sponge is its elasticity and softness. Therefore, the sponge can be divided into high rebound, low rebound, hard, soft and super soft. With the interpretation of the sponge density by the relevant national departments, the density is higher than 45 density for high-density sponges, the density between 45-18 is medium-density sponge, and the low-density sponge is less than 18. Use the sponge material selected from the sofa sponge density to make sponges of different densities according to different parts of the sofa, but the high quality sponges are generally high rebound.
