What is a sponge? Familiarity with a porous polymer material

Sponge foam, also known as foam sponge, is a polymer material that gets a porous, light and soft structure by creating gas bubbles during the production process. This cellular structure gives it unique features such as shock absorption, insulation and light weight. These properties have made sponge foam one of the most widely used materials in various industries, especially the furniture and sleeping goods industry.

types of foam sponge; Which one is right for you?

Sponge foams are produced in different types, each of which has its own characteristics and uses. Knowing these differences will help you make the best choice for your needs.

Polyurethane foam (PU): the champion of the furniture and mattress industry

The most common and well-known type of sponge foam is polyurethane. Due to its softness, extraordinary flexibility and reasonable price, this foam has become an ideal option for the production of sofa foam, mattresses, car seats and all kinds of cushions. The industrial production of this type of foam requires high precision and technology, which is carried out by advanced foam injection devices.

Polyethylene (PE) foam: a durable option for packaging and insulation

Polyethylene foam has a denser and more resistant structure than polyurethane. This feature makes it very suitable for protective applications such as the packaging of sensitive goods, sound and thermal insulation, and the production of sports flooring.

EVA foam and latex: flexibility and health together

EVA (Ethylene Vinyl Acetate) foam is used in the production of shoes, toys and sports mats due to its softness, flexibility and excellent resistance to water. Latex foam, which is made from the natural sap of the rubber tree or synthetic materials, is used in the production of luxury medical mattresses and orthopedic pillows due to its high elasticity and hypoallergenic properties.

Abar Furniture's expert guide: from cold foam to 35 kg sponge

When buying or repairing a sofa, knowing the types of sofa sponge is very important. The quality of the cloud used in the living room will have a direct effect on the comfort and durability of your furniture.

Types of sofa sponges and their key differences

Generally, two types of foam are used in the furniture industry: normal sponge and cold foam. Common sponges are classified by density (weight per unit volume). For example, the price of 35 kg sofa sponge is higher than the 20 kg sponge, because it is denser and therefore more durable. But the main star in high-quality furniture is "cold foam". Due to the different production process, this foam has a much better elasticity, it does not suffer from loss and indentation during long-term use, and it is the best option for the sitting area of ​​the sofa. In contrast, ordinary sponges with a lower density are usually used for sofa backs and handles.

Foam sofa price and smart buying tips

The price of sofa foam depends on several factors such as type (cold foam or ordinary sponge), density and thickness. Although searching terms such as "Digikala cold foam" or "Digikala cloud sofa price" can give you an overview, it is recommended to refer to specialized cloud and foam sellers for professional purchase and quality assurance. Keep in mind that investing in a quality sofa foam will extend the life of your sofa by several years.

The world of sleep goods: from foam mattress to smart foam

The comfort and quality of sleep is directly related to the mattress you use. Nowadays foam mattress has become one of the most popular options.

A soft and comfortable mattress is not necessarily the best option for your spine health. Standard mattresses are a combination of different layers of foam with different densities. Hoshshov mattress foam and other reputable brands also use the same technology. In the meantime, smart foam or memory foam is considered a revolution in the sleep product industry. This foam reacts to the temperature and pressure of the body, takes the shape of the body, and when the pressure is removed, it slowly returns to its original state. This feature distributes the weight evenly and reduces the pressure on the joints. The price of medical mattress foam, which uses memory foam or latex, is usually higher than ordinary foam mattresses.

Frequently asked questions

1. What is the main difference between cold foam and hot foam?
The main difference is in the production process. Cold foam is produced at a low temperature and with indirect heat, which creates a more open cell structure and a much higher state of elasticity. As a result, cold foam is more durable and ideal for sofa seating.

2. What is meant by the density of a sponge (for example, a 35 kg sponge)?
Density refers to the weight of one cubic meter of sponge. A 35 kg sponge means a block of one meter by one meter by one meter weighs 35 kilograms. The higher the density, the more compact, hard and durable the sponge is.

3. Is memory foam or smart foam suitable for everyone?
Smart foam is very useful for most people, especially those who suffer from joint pain or back pain, due to the reduction of pressure points. However, some people may not like the feeling of being immersed in it or may feel warmer due to its heat retention properties.

4. Where should you go to buy bulk foam and super sofas?
For bulk and professional purchases, it is better to go to the main markets selling foam in big cities (such as Tehran's foam market in Fedaiyan Islam Street) or directly to reliable factories and suppliers to ensure the quality and the right price.
