How to identify the advantages and disadvantages of sofa sponge?

Some ways to tell if a sponge is good or bad:

Clause. 1. Look at the appearance, generally speaking, the more delicate the appearance of the sofa sponge, the better, that is, the smaller the pores, the better, (except for space sponge and chaotic space sponge).

Clause. Second, when pressed by hand, the fluffy sponge that can rebound quickly is high-quality, and the sponge that shrinks into a ball is a low-quality sponge.

Clause. 3. Smell the smell, the normal sponge will have a little smell, but if there is a pungent smell, it is an inferior sponge.

Clause. Fourth, look at the strength of the sponge, high-quality sofa sponge is not easy to be torn, if the sponge is broken by hand, it must be an inferior sponge.

The resilience of the sofa is relatively easy to judge, and the sofa with high-quality sponge will generally have a depression of 5-10 cm, and the bounce time is very fast, and the surface is flat. And the sofa with low-quality sponge is the opposite.

As one of the main materials of the sofa, sponge directly affects the service life of the sofa and human health, so when buying a sand delivery mattress, consumers must experience it first-hand and observe carefully in order not to be deceived by the appearance and buy their favorite products.

The main types of quality sponges are A cotton, pink ultra, ultra-soft ultra, blue super, gray high elasticity, white elasticity, green high elasticity, yellow high elasticity, color red glue, high-density foam, etc. The quality of each species is different.

1 A cotton: density of 13KG cubic meters,;

2. Pink super: density of 25KG cubic meters;

3 Super soft super; THE DENSITY IS 36KG CUBIC METERS;

4 Lan Chaoli: density of 30KG cubic meters;

5. Gray high elasticity: density of 35KG cubic meters;

6. WHITE BULLET: DENSITY OF 35KG CUBIC METERS;

7. Green high elasticity, yellow high elasticity: the density is 40KG cubic meters, high-grade sofa cushion sponge, better elasticity than white elasticity;

8 Rainbow bomb: also known as violet, with a density of 27KG cubic meters, mainly used for backrests, which is softer than ultra-soft.

9. High-density foam, with a density of 50KG cubic meters, has the highest density, the best resilience and the most expensive price among all sponges.

The resilience of the resilient sofa is relatively easy to identify, and the sofa with high-quality sponge will generally have a depression of 5-10 cm, and the rebound time is very fast, and the surface is flat. And the sofa with low-quality sponge is the opposite.

There are a few tips for judging the quality of a sponge:

The first is to look at the appearance, generally speaking, the more delicate the appearance of the sofa sponge, the better, that is, the smaller the pores, the better, (except for space sponge and chaotic space sponge).

Secondly, a fluffy sponge that rebounds quickly when pressed by hand is a high-quality sponge, and a sponge that shrinks into a ball is a low-quality sponge.

Third, smell the smell, the normal sponge will have a little smell, but if there is a pungent smell, it is an inferior sponge.

Clause. Fourth, look at the strength of the sponge, high-quality sofa sponge is not easy to be torn, if the sponge is broken by hand, it must be an inferior sponge.

A good sponge has good resilience, fast recovery speed, and is not easy to damage, while inferior sponges may collapse and other problems after one or two years of use, with a short service life, and may contain harmful substances. There are several sources of inferior low-cost sponge in the sofa, such as using cheap sponge, using leftovers to cut and fill in the cushion or backrest, the worst and least environmentally friendly is to use recycled cotton, recycled cotton contains more formaldehyde, and there is almost no elasticity, even if it is used to fill the bottom of the cushion.

1.Looking at the appearance, in general, the more delicate the appearance of the sofa sponge, the better, that is, the smaller the pores, the better, (except for space sponge and chaotic space sponge).

2.The fluffy sponge that rebounds quickly when pressed by hand is high-quality, and the sponge that shrinks into a ball is low-quality sponge.

3.Smelling the smell, a normal sponge will have a little smell, but if there is a pungent smell, it is an inferior sponge.

4.Looking at the strength of the sponge, the high-quality sofa sponge is not easy to be torn, if the sponge is broken with a little hand, it must be an inferior sponge.

5.Try it out for yourself, and the sofa made of high-quality sponge has a depression of about 10 cm when you sit on it.

The sponge of the sofa mainly includes spray cotton, doll cotton, pearl cotton, shaped cotton, etc.

Sofa sponge quality discrimination skills:

1.Appearance: Except for the special large empty and chaotic sponge, the more delicate the appearance of the general sponge, the smaller the stomata the better.

2.Feel: It can rebound quickly, fluffy sponge is good, and the stiff sponge is inferior.

3.Tensile performance: A good sponge has at least 80 tensile elongation, and those that cannot be reached are low-grade goods.

4.Odor: Normal sponges have a slight smell, but if the smell is unbearable, it is the use of inferior raw materials.

5.Tear strength: A good sponge is not easy to tear, and it must be a cut of corners if it breaks with a light finger.

Press the rebound of the feel, and if you press down a concave position, the elasticity and density of the quick reset should be okay. This professional will feel it from the feel. If the flavor is still strong, it may be made of very low-quality sponge.

It's inferior! The sponge is divided into high foam, medium bubble and low foam. The high foam is better, soft, elastic and rebounds quickly.
