familiarity with foam sofa
Foams, which have a longer lifespan than ordinary sponges, are made from a combination of special chemicals. Also, because foams are made with a specific ratio in the oven, they are marketed in different qualities. Foam is used in furniture and car seats.
foam sofa types
Cold Foam:
Cold foam, which is also called memory foam, is one of the types of sofa foam that is used in the mattress and sleeping goods, furniture and decoration industries. Directly with low temperature is in the manufacturing process; for this reason, it has a long life, because low temperature helps the formation of cold foam molecules and its elasticity, and also because it is softer than warm foam for sofas in the area The floor is very useful. And it has a longer lifespan than sponges and allows sofa manufacturers to guarantee their sofa for up to 24 months.
warm foam:
Other types of sofa foam include hot foam or soft polyurethane foam. The way to produce hot foam is that it must be cooked at a high temperature and with direct heat. The main feature of hot foam is its hardness, although it will become softer over time, and it usually has a shorter life span than cold foam and eventually becomes hollow. falls Hot foams are used in the furniture industry, sleeping goods, packaging industry, washable clouds, etc.
sponge:
The sponge is actually the same as the old eraser board, which is also known as Abar in the market, but in larger and different dimensions. . (It means 30 kilo sponge density)
Maybe the name of these raw materials at first leads the thoughts towards low quality and unreliable product, but it is not like that. Sponges that have a high density and weight are very good due to their softness and elasticity.
The higher the density of the sponge on the floor of the furniture, the longer its life. Having a high density and weight is one of the characteristics that gives softness and quick elasticity to the sponge. The higher the density and weight of the sponge, the higher the quality and service life will be. The seat of the comfortable furniture is recommended by most of the manufacturers of the comfortable furniture, 35 kg high-density sponge.
When buying a sponge, you should consider two important things to consider:
Pay attention to the weight of the sponge when buying, that is, if they offer you two sponges of equal dimensions to choose from, the sponge has better quality and is heavier, and in fact, the heavy weight of the sponge is caused by the density of the sofa sponge per unit volume. which indicates the better quality of the sponge and its longer life.
Difference of Cold Foam and Hot Foam and Sponge
The elasticity of cold foam is higher than warm foam and it is softer than warm foam. Cold foam is usually used in the floor part of comfortable furniture because of its softness and longevity compared to warm foam.
One of the most important features of hot foam is its stiffness, this property gradually disappears and the stiffness of the foam decreases over time, also the elasticity of this foam is gradually affected and after some time it completely It has been lost, so to speak, it has been left behind.
But to make cold foam, very low heat or indirect heat is used, and one of the most important features of cold foam is its high elasticity.
The softness of cold foam is clearly felt. For this reason, this foam is used in the construction or repair of sofas, because using it creates a lot of comfort in the body of the person who sits on the sofa, and the durability of this foam is much longer than warm foam.
