Memory foam mattresses are mattresses made of memory foam. Memory foam mattresses change the softness and hardness according to human body temperature, reducing sleep pain and other problems. At the same time, they can extend sleep time and improve sleep quality. It has been widely recognized by consumers. Today, the editor will explain the memory foam mattress from three aspects: the material characteristics of the memory foam mattress, the product technology of the memory foam mattress, and the purchasing skills of the memory foam mattress, for your reference. .
Characteristics of memory foam mattress materials: temperature sensing properties
It senses the temperature of the human body and gradually becomes softer. At the same time, it absorbs the pressure of the human body and adjusts the human body to the most comfortable posture. As for the lower part that is not exposed to human temperature, it still maintains sufficient support;
Viscoelastic properties of memory foam mattress material
It means that the product sinks under pressure, but It will not show strong rebound force (such as clay sinking under pressure); when the pressure is removed, the product will gradually return to its original shape (such as spring recovery); "slow rebound" is also called "zero rebound" in business. "Pressure sponge" means that when you lie on it, you feel as if you are floating on the water/or in the clouds, and there is no sense of pressure on your skin; in fact, the slow rebound material can adjust the pressure of irregular shapes to the most balanced state, that is, it can slowly deform and adapt. It can compress objects and provide the most uniform support.
The material characteristics of memory foam mattress are breathability, antibacterial and anti-mite.
The open cell structure of memory foam inhibits the growth of bacteria and mites, and it is still healthy and safe for long-term use, especially Suitable for pregnant women and children who are prone to allergies. At the same time, it is a breathable material, so people sleeping on it will feel transparent and not stuffy.
The filling process of memory foam mattress products
Generally, the leftover materials from the cutting process are broken and filled into products to save costs. It is the simplest and cheapest memory foam product manufacturing process. kind of.
The cutting process of memory foam mattress products
The assembly line or large cabinet is used to foam and then cut into the required shape. Due to the simple production, fast speed and high output, the price is relatively low. Low. However, the memory performance of the product remains for a short period of time. And it can only be cut in two dimensions, and there may be debris on the surface, so the product quality of this process is second to none.
Memory foam mattress product molding process
The product is foamed separately in a special mold. It can be molded into any shape according to the mold, with smooth surface, high density, slow rebound and long-lasting elasticity. It is the production process with the best quality at present, but it is also complex and slow to produce, and the price is also the highest among the three processes.
Purchase density of memory foam mattress
Density is the basic indicator of high-end slow rebound material. Generally, the density of polyurethane can be 70~150D through molding process, and can be achieved through cutting process. 40~100D. Due to technical bottlenecks and differences in equipment, the density of domestically produced polyurethane is generally lower than 100D, while the highest abroad can reach 150D. Secondly, even products with the same density will vary greatly, mainly in the formula. , technology and raw materials are different, that is to say, high-end slow rebound materials must be high-density, but high-density materials are not necessarily high-end materials.
When purchasing memory foam mattresses, rebound time
Many consumers believe that the longer the rebound time, the better. This is a misunderstanding. A better rebound time is about 3-5 seconds. If it is too short, it will not achieve the slow rebound effect; if it is too long, it will make the body stiff (think about if you turn over, it will not rebound for a long time);
Purchase and manufacturing process of memory foam mattress
There are two manufacturing processes for slow rebound: cutting and molding. Cutting is to buy the finished slow rebound sponge and cut it into the shape of a pillow. Because molding relies on cutting rather than mold additives, no other additives are added, so even pure polyurethane can only have a density of 40~70; molding Plastic ones are made using molds through a series of processes such as foaming and vacuuming, which are much more complicated.
The density increases to about 70 to 100, which gives a good hand feel and the service life is related to this;
Purchase memory foam mattresses with hand feel and temperature sensing
High-end slow rebound sponge feels very comfortable , it feels like kneading dough when you pinch it. It rebounds slowly and either feels a bit jittery or a bit stiff. At the same time, this high-end slow rebound also has good temperature sensing and will become softer as the temperature rises. When the human body comes into contact with the slow rebound material, as the body temperature is transferred, the pillow will become softer and can Better wrapping and supporting the human body;
Memory foam mattress purchase life
High-end slow rebound will not deform after more than 5 years of use, but the cutting process or The quality is a bit poor and can usually only be used for 1-2 years
