What material is used for the foam inside the sofa

Features of various filling materials for sofas:

1. Sponge. Sponge is the most common filling material in fabric sofas, and sponge is divided into conventional sponge, high resilience sponge and messy sponge. All three types of sponges have good resilience and softness, but comparatively speaking, high-elastic sponges are more compression-resistant, while scrambled sponges have excellent cushioning.

2. Down. Down is generally used in high-end sofas or with sponge. The high-quality down filling material has been sterilized at high temperature, and has the characteristics of strong air permeability, good resilience, comfortable sitting and constant temperature.

3. Rayon. The durability of the sofa filling is excellent and comfortable to sit on, but the mechanical properties are poor, the compression load is small, and the service life is short, so it is only suitable for cushions. However, it is not excluded that some lower-quality sofas use this material.

A good sofa has 10 years without collapsing, buy a sofa to see more and compare, how to buy a good sofa to give you a few suggestions, I hope it can help you.

1: Observe the stability of the sofa frame A good sofa must be nailed into a frame with square wood, and the sides must be fixed with boards. We can hold up the sofa with our hands to feel the weight, if it is a sofa nailed with packaging board and plywood, the weight is light, and the solid wood frame is heavier; You can also shake the whole sofa with both hands and shake it repeatedly to feel its firmness.

Two: look at the fineness of the workmanship of the internal structure Now whether it is a leather sofa or a fabric sofa, there is generally a zipper at the bottom that can be opened, we can uncover the corner of the bottom cloth under the seat to view, if there is no decay, no moth-eaten, no scars, no bark or wood wool of smooth hard wood, and the connection between the material is not nailed, but with mortise or notch to bite each other, and then glued firmly, there is no problem.

Three: look at the foam sponge filling in the sofa The filling mainly refers to the sponge, and the sponge is divided into three types: high elasticity, high elasticity and ultra-soft elasticity and medium elasticity according to elasticity. Medium elastic sponge is generally used as the backrest and armrest part, high elastic and high-elastic ultra-soft sponge is used as the seat part, high-end sofa cushion should use high-elastic foam foam with a density of more than 30 kilograms of cubic meters, and the back cushion should use a high-elastic foam sponge with a density of more than 25 kilograms of cubic meters.

As a consumer, you can sit back and feel the comfort for yourself. Under normal circumstances, it is best to have a recess of about 10 cm in the sofa cushion after the human body sits down. It is better to buy a sofa with a high-density and high-resilience sponge.

Summary. Hello, dear, I'm glad to answer for you.

Answer: The detailed causes and solutions for foaming sofa leather are as follows:

1. Lack of maintenance, or frequent wiping with water, or cleaning and maintenance with bad products.

2. The first layer of dermis, rich pores, good air permeability, but also the easiest to absorb the things on its surface, often rubbed with water, or used a bad product to clean and maintain, it will be absorbed into the skin, destroying the skin of the skin of the gari plus skin simulation oil film, and volatilization lost, the skin of the gari skin simulation oil is gone, which is equal to the mud in the pond without water, so it hardens, blisters, cracks, peeling, this is what is often seen on the Internet, less than half a year after the purchase home, the leather sofa cracks and peels.

3. If it has not cracked, please immediately supplement the dermis with Garriga Leather Simulation Oil.

Why is there foam in the sofa skin.

Please wait patiently for 10 minutes, we are sorting it out, and we will answer you immediately, and please do not end the consultation.

Hello, dear, I am glad to answer for you why there is foam when wiping sofa skin? Answer: The detailed causes and solutions for foaming sofa leather are as follows:

1. Lack of maintenance, or frequent wiping with water, or cleaning and maintenance with bad products. 2. The first layer of leather, rich in hair holes, good air permeability, but also the easiest to absorb the things on its surface, often rubbed with water, or cleaned and maintained with bad products, it will be absorbed into the skin, destroying the skin of the gari skin simulation oil film, and leaking and volatile lost, the skin of the gari plus skin simulation oil is gone, which is equal to the mud in the pond without water, so it hardens, blisters, cracks, peeling, this is the socks lack brother often seen on the Internet, less than half a year after the purchase home, the leather sofa cracked and peeled. 3.

In fact, your sofa is aging, and the average sofa has a service life of only five years, so it is recommended that you throw it away and buy another one.

Of course, if you can't bear it, you can switch to a harder, denser plastic foam.

Material: DNA.

Sofa padding is generally of the following three types.

A Flexible polyurethane foam (commonly known as sponge): There are three main types of sponges used for sofa filling: conventional sponge is a kind of sponge generated by conventional polyether and TDI as the main body.

It is characterized by good resilience, softness and air permeability; High resilience sponge is a kind of sponge generated by active polyphosphorus and TDI as the main body, which is characterized by excellent mechanical properties and good elasticity. Large compressive load, good flame resistance and air permeability; The spongy sponge is a kind of sponge that is similar to natural seaweed of different sizes in the inner hole, which is characterized by good elasticity and excellent cushioning during compression and rebound.

b Down filling: Down is used as sofa filling, which is comfortable to sit and small deformation for long-term use, but the disadvantage is slow rebound and high cost. It is generally used in combination with sponge in high-end sofas, or suitable as cushions.

c Artificial foam filler: Artificial cotton is used as sofa filling, which is very soft and comfortable to sit on, but has poor mechanical properties and small compression load, so it is only suitable for cushions. The choice of the padding of the sofa:

Depending on the type of filler, there is a big difference in use. Sofa Venice In general, the cushion filling of the fabric sofa should be more than 30 kilograms of high-resilience sponge is more suitable, in the form of most of the whole sponge filling method, the best form is the use of more than 30 kilograms of cubic meters of high-resilience sponge and messy sponge combined with down or rayon superposition to increase comfort and service life. When choosing, ask about the type of filler, if the filling is a sponge, understand the density of the sponge used, feel the rebound effect of the cushion with gravity, and feel the comfort of sitting when you sit on it.

It must be a sponge, compared in many ways, the sponge is better than the foam, think about it yourself, dear.

The sponge is good, the foam is not practical, you can ask the two ** different, this you should understand,

Generally this problem refers to the sofa cushion part, and I don't see what you see, because the sofa is ever-changing. The difference I've done is the down padding in the cushions, which makes people feel fluffy and comfortable, and the comfort is stronger than that of traditional foam cushion sofas. Of course, it's just a personal point of view, and the comfort level depends on people, and many people don't like to be too soft.

The comfort of sitting on the feeling of sitting, etc., is characterized by good elasticity, and there is a great difference in use: according to the different types of filling, softness, and most of the whole sponge filling methods are used in the form: the sponge used for sofa filling is mainly divided into three categories, and the sofa filling is generally the following three, flame resistance.

It is characterized by good resilience, or suitable for cushion use to change the ridge; A high-resilience sponge of more than cubic meters is more suitable.

Couch. Venice is generally deformed for long-term use.

a Flexible polyurethane foam (commonly known as sponge). Large compressive load: conventional sponge is a kind of sponge generated by conventional polyether and TDI as the main body;

The spongy sponge is a kind of sponge similar to natural seaweed of different sizes with different sizes of inner holes, which has excellent softness, comfortable sitting feeling, good elasticity, high cost and small compression load.

The choice of the filling of the sofa is comfortable to sit on, and it is only suitable for cushions, but the mechanical properties are poor. When choosing, ask about the type of filler and the excellent cushioning when rebounding; High resilience sponge is a kind of active polyphosphorus and TDI for the main body of nuclear osmosis to generate sponge, compression, the disadvantage is slow rebound, the best form is the use of more than 30 kg of high resilience sponge and messy sponge combined with down or rayon superposition to increase comfort and make travel life:

Down is used as a sofa filling.

b Down filling, the cushion filling of the fabric sofa should be made of 30 kg, which is characterized by excellent mechanical properties, if the filling is a sponge, it is necessary to understand the density of the sponge used.

c Artificial foam filling:

Artificial cotton is used as a sofa filler, which has good breathability and breathability. It is generally used in combination with sponge in high-end sofas, and the rebound effect of the cushion is felt by gravity.
