What is a sofa sponge?
In fact, the sponge is a kind of porous and lightweight material that consists of polyol (Polyol) isocyanate (TDI) and water, and water can help to expand and increase its volume. Sponges are produced in different thicknesses, and the thicker these materials are, the higher their density will be. It should be noted that the more dense the sponge is, the longer it can last. This is why high-density sponges are used in furniture production.
Sponge and sofa foam are among the most common materials that are used in the production of all kinds of home and office furniture, and each of them can have many features and capabilities. These constituent parts are produced in different diameters and thicknesses. It is interesting to know that the production method of each of them is different. These materials can be used in different parts of furniture, such as soles, backs, and handles, or even combined with other building materials.

Types of sofa sponge
🔹 Normal sponge This type of sponge, in addition to being baked at a high temperature in the oven, is also combined with a stone powder called mill, which is a distinctive feature of this sponge, which is its hardness, which, of course, decreases over time due to use. And the sponge settles down and loses its shape and doesn't have its elasticity anymore, and after a few years it falls and so-called falls, and this is the reason why Nader Sarvas does not use this sponge. 🔹 HR sponge: It is one of the types of polyurethane sponges. HR sponge is also named because of the use of indirect heat or low temperature, in the manufacturing process. Low temperature gives more opportunity for the formation of the molecules of this sponge, and for this reason, the elasticity of this sponge is higher than normal sponges and it is softer than normal sponges. They do not become self-resilient.
