How to solve the problem of sofa sponge softening

This is a quality problem with the sponge itself, which cannot be restored and can only be replaced.

How to choose a sponge:

1.When choosing a sponge, it is mainly based on its tactile feel and elasticity as the primary factors. It should be soft to the touch and malleable.

2.Since the sponge is afraid of light, including the lights in the store, it may damage its quality, so when buying a sponge, if it is hung in a row, do not take the first one, you should take the back one, because the sponge in the back will not shine a lot of sunlight.

3.In addition, one of the most practical ways to distinguish is to fold the sponges in half and rub them against each other. If the sponge crumbs fall off without a few rubbings, the sponge cannot be bought.

Sponges are the most primitive multicellular animals, which have lived in the ocean 200 million years ago and have developed to more than 10,000 species, accounting for 1 15 of the marine animal species, and are a huge "family". Sponges can be found everywhere in the ocean, from the intertidal zone to the deep sea, from the tropical ocean to the Antarctic ice sea. Sponges can live not only in the ocean, but also in rivers and lakes, and the prosperity of the sponge family can be seen.

Perhaps it is because the sponge has a soft body and lives in the ocean, hence the name "sponge". I have no mouth, no digestive cavity, and no central nervous system, and am a most primitive animal. The small holes that cover the body are filled with flagella and a sieve-like ring, which can be collected by the swing of the whip into the seawater, which carries oxygen, bacteria, microalgae, and other organic detritus, which is then filtered through the ring, and finally becomes the nourishment for the sponge to survive.

Due to the development of science and technology, all sponges are now used artificially.

It's very simple, if it's a sofa cushion, you can turn the side up, pat it down hard, and feel it bulge in the middle. If it's fixed, just buy a thicker cushion to sit on.
