Teach you how to distinguish sponge
For the current living standard, when every household is buying things, it is often the beginning of paying attention to quality, but it is not the best to sit on a sofa with good quality because its raw material is sponge with good quality. Now there are many kinds of sponges, and they are used in the sofa as raw materials. We can’t tell whether it is good or bad from the appearance. We will teach you how to distinguish a sponge from a good one in a professional way:
If the density of the sponge is low, it is relatively soft to sit up, but it is difficult to rebound after sitting for a long time. If the density of the sponge is high, it feels hard to sit up, but it will deform after a long time. It feels very ugly, and the sitting feeling is not good. So, it’s not that the denser the sponge is, the better, but it’s really more expensive. Relatively speaking, the cushion of a good quality sofa should be the product of many layers of sponges with different densities. Such a sofa is not only comfortable to sit on, but also not easy to deform.

Then how to distinguish the quality of sponge can be seen from the following aspects:
1、 The rebound rate is mainly determined by the density. The higher the density is, the easier it is to rebound.
2、 The compression deformation rate is less than 5% for the better, less than 7% for the second, and less than 10% for the worse. The third is to look at the mechanical property requirements. Mechanical property requirements are professional terms. In a language that we can understand, it means how many times people can sit, generally 60000 times, 40000 times next, and 20000 times worse.
Generally, high-grade sofas use high elastic sponges with the most suitable density. This material can improve the comfort of sitting and lying. Some foam have been softened without reducing the density. Some use built-in springs, which will make sofas more elastic and slow down aging. The previous small editor also explained how to distinguish the quality of sofa. I think you must also distinguish the real good quality sofa as the five searches explained.
