Question 1: What is memory foam? Slow rebound, also known as memory foam, is a polyurethane polymer with an open-cell structure. , this material has special viscoelastic properties, reflects very soft material properties, and has strong impact energy absorption capabilities. The molecules of this material are very sensitive to temperature, so it is also called temperature-sensitive memory foam.
The birth of memory foam can be traced back to a 1962 study by the United States Space Agency (NASA): the design of the Apollo command module lifesaving system. This material was developed and used on the seats of the spacecraft. It can absorb the huge impact caused to astronauts when the rocket (spaceship) takes off, the spacecraft returns to the atmosphere, and some unexpected situations (such as falling), and improves the protection and comfort of the seat for astronauts. Because memory foam was originally created by the NASA, it is often called space memory foam, which means technology derived from the NASA. This technology was first mentioned in the NASA report "Human Survival in Aircraft Emergencies". The author of the report was the inventor of memory foam, Charles Yost, an engineer working at NASA at the time. In the 2005 NASA Spinoff document "NASA Spinoff" 2005, the origin of memory foam and the development and application of this technology in the following decades are described in more detail.
When pressed by external force, the (Open-Cell) molecules of this material will "flow" and shift to fit the contour of the contact surface of the pressure object, thereby evenly distributing the pressure to The entire contact surface will slowly return to its original shape when the pressure is removed, so this material was originally called "Slow Spring Back Foam". NASA's Ames Research Center fully applies this material to its new aircraft seat design, which not only provides good impact protection for passengers in accidents, but also improves the comfort experience of passengers during long-term flights. .
Question 2: What is memory foam? What is memory foam? The following is an introduction through material sources, material characteristics, and applications.
Ⅰ: Material source
Memory foam, also known as slow rebound, is a polyurethane polymer with an open unit structure. It has very soft characteristics and It has special viscoelastic properties and also has strong absorption capacity. Because it is sensitive to temperature, it is also called temperature-sensitive memory foam. Memory foam was first created by the NASA to improve the protection and comfort of seats for astronauts, so it is often called space memory foam.
Ⅱ: Material Characteristics
1: Temperature Sensing Characteristics
Memory foam is particularly sensitive to temperature. As long as it comes into contact with the human body, it will gradually become soft. And it can absorb the pressure of the human body and automatically adjust to the most comfortable state.
2: Viscoelastic characteristics
Viscoelastic characteristics mainly mean that once the memory foam is under pressure, it will not immediately show strong rebound force, but will gradually return to its original shape. .
Generally, memory foam cannot be washed. Due to the material characteristics of memory foam, it cannot be directly exposed to the sun. Exposure will cause the memory foam to age or turn yellow, thus affecting the appearance of the memory foam.
Question 3: What is memory foam? Memory foam is also called slow rebound. It is a polyurethane polymer with an open-cell structure. The material has special viscoelastic properties, embodies very soft material properties, and has strong impact energy absorption capabilities. The molecules of this material are very sensitive to temperature, so it is also called temperature-sensitive memory foam.
The birth of memory foam can be traced back to a 1962 study by the United States Space Agency (NASA): the design of the Apollo command module lifesaving system. This material was developed and used on the seats of the spacecraft.

In the 2005 NASA Spinoff document "NASA Spinoff" 2005, the origin of memory foam and the development and application of this technology in the following decades are described in more detail.
The (Open-Cell) molecules of this material are affected by "Back Foam" (ie, slow rebound foam). NASA's Ames Research Center will fully apply this material to its new aircraft seats The design can not only provide good impact protection for passengers in accidents, but also improve the comfort experience of passengers during long-term flights.
Features and functions
Memory. The excellent performance of cotton materials in various application fields is due to the special viscoelastic properties of the material. That is, when the material is impacted by pressure, it not only undergoes elastic deformation (accumulatory deformation) that satisfies Hooke's law, but also At the same time, irrecoverable plastic deformation (energy-consuming deformation) occurs. In other words, the deformation of memory foam is an organic combination of these two deformations. Plastic deformation will consume most of it (with special formula, it can absorb more than 90%). Impact energy, and part of the energy accumulated in the elastic deformation part, can slowly restore the memory foam material to its shape before being compressed after the external force is removed (the reason why it needs to be slowly restored is because of the part of the energy accumulated in the elastic deformation. , need to pull some of the displaced molecules back to their original positions)
This characteristic allows the memory foam material to exhibit:
When used as an impact buffering material, it has a strong impact. The energy absorption capacity and the small rebound force on the pressure object (or human body) in contact with it are the direct cause of the damage to the protected object or human body under high impact conditions. When cushion product materials are used, the pressure they receive is similar to static pressure. Under such pressure, the molecular structure of the memory foam material will "flow" shift and deform to fit the contour of the pressure surface, spreading the support points to the entire The contact surface allows the pressure to be dispersed across the entire contact surface. This feature is called the "even pressure dispersion characteristic" of memory foam. When a person sits or lies on a cushion made of memory foam, the pressure is evenly distributed and the body is not affected. There are pressure concentration points, and the comfort is greatly improved. Problems such as bedsores caused by long-term high pressure compression lead to blood circulation obstruction. Therefore, after special preparation and improvement, this material has even better preventive effects. Ordinary sponges have a better soft touch; at the same time, the open-cell molecular structure of its material is similar to the cell structure of the human body and has good compatibility with the human body, which makes memory foam materials widely used in the field of medical rescue.
The above characteristics are destined to play an increasingly important role in people's lives, and today's facts prove that this is indeed the case.
Question 4: What is memory foam? Memory foam, also called slow rebound, was developed in the 1960s by HEALTHMAN, a subsidiary of NASA. It is an open cell structure with the ability to sense temperature and reduce pressure. Characteristics: It can also be called a temperature-sensitive pressure-reducing material. The American company HEALTHMAN applies this material to the space shuttle.
In order to relieve the pressure on the astronauts and protect the astronauts' spines, especially when the space shuttle returns and leaves the ground, the pressure on the astronauts is the greatest and most dangerous. In order to protect the safety of astronauts, this material was invented. He and GPS (Global Positioning System) are known as the two major inventions of space technology. The biggest science in the 21st century will be life sciences, and space technology has made great contributions to the research of human life sciences. In the early 1990s, the Swedish Fagerdala company developed it again as a civilian (medical) product, which was first widely promoted and used in medical emergency and monitoring systems. Then it spread rapidly in developed countries, especially health-conscious countries like Japan.
The civilian slow rebound material of the American company HEALTHMAN is a second-generation temperature-sensing pressure-reducing material (Visco-Elastic) developed by the Healthman Healthy Sleep Research Center under NASA. . The so-called temperature sense refers to the sensing of human body temperature. Stress reduction is the absorption of stress from the human body. When the human body comes into contact with the material, the material will sense the human body temperature and gradually become softer. At the same time, it absorbs the human body pressure, thereby adjusting the human body to the most comfortable posture. What is shown on the mattress and pillow is that when a person lies on the mattress and pillow, the spine is in an S-shaped natural physiological curvature when lying on the back, and the spine is not curved when lying on the side. At the same time, mattresses and pillows have no pressure points on the human body, this is the material.
[Edit this paragraph] Characteristics of mattresses
The slow rebound memory foam mattress senses human body temperature through unique temperature-sensing memory particles, providing comfortable support and hardness; at the same time, it can sense , memorizes the curves of the human body, perfectly shapes according to the ups and downs of the human body, and conforms to protect the natural bends of the neck, waist, hips, and legs. Whether lying on your back or side, it can keep all parts of the human body in a stress-free state, promote blood circulation, and relieve the body Fatigue and soreness avoid the fatigue and stiff neck caused by the overhead bending of the neck and waist caused by traditional mattresses, allowing the cervical spine and spine to completely relax and rest, thereby reducing the number of unnecessary turnings during sleep and alleviating snoring, muscle soreness and other conditions. .
1. Whether lying on your back or on your side, the comfort effect can be automatically shaped according to the needs of the human body, effectively reducing the pressure on the human body to zero pressure, offsetting the reaction force, and completely relaxing the neck, shoulders and waist;
2. Avoids the fatigue and stiff neck caused by traditional mattresses that cause the neck and waist to bend overhead;
3. Does not hinder blood circulation, is less likely to cause fatigue and soreness, and reduces unnecessary sleep. Turn over more times to increase the time of deep sleep;
4. Excellent material selection, breathable and not stuffy, long service life;
Question 5: What material is memory foam made of? It is an open sticky cell material that is extremely sensitive to temperature and can accurately shape the body contours of the human body
Question 6: How to identify the pros and cons of memory foam products? With the improvement of living standards, people's health awareness is also increasing. Choosing the right mattress and pillows can ensure that we sleep more soundly and healthily for 1/3 of our lives. But in the face of so many well-known memory and space cotton products on the market, how can we find products that actually have better pressure-reducing effects? Take a look: When the steel ball is thrown vertically on the material block, if there is no rebound and the pressure is absorbed instantly, it means that the material has a good decompression effect. Second touch: When you touch the material block of the product with your hand, you will find that the material will become delicate and soft with the transfer of hand temperature, indicating that the material has temperature-sensing particles. Only memory foam with temperature-sensing effect can have good and reducing effects. pressure effect. Three pinches: When you pinch the product with your hands, there is obviously a slow rebound phenomenon, indicating that the product has a certain decompression effect. Four-lying: Lie flat on the mattress and feel so comfortable that you don’t want to turn over. If your waist is supported and does not feel suspended when you touch it with your hands, it means that the product absorbs pressure well and has good support, which can reduce the number of turning over and improve sleep quality
Question 7: What is the difference between latex and memory foam mattresses? Nowadays, two materials are more popular in high-end mattresses, namely memory foam and natural latex.
So, what are the advantages of memory foam and natural latex? Memory foam can promote sleep, protect the spine, and relieve body pain; natural latex material is natural, has good breathability, high comfort, long service life, and is hypoallergenic. When buying a mattress, these two new materials are of great concern to everyone. These two material mattresses have many similarities. For example, they are both high-end products and relatively expensive. For example, they have many similar advantages: promoting sleep, protecting the spine, relieving pain, antibacterial and anti-dust mites, etc. What is the real difference between memory foam and natural latex? How to choose among them? Let the Golden Oak experts briefly introduce them to you.
Memory foam is a synthetic material that originated from NASA and was originally used to reduce the physical stress experienced by astronauts during flight. Memory foam is primarily made of polyurethane. Natural latex comes from the sap of rubber trees and is a natural and environmentally friendly material.
Memory foam is a heat-sensitive material that forms a shape that conforms to the contours of the body under the action of body temperature and body pressure. This can evenly distribute body weight and reduce body pressure, thereby promoting sleep, protecting the spine, and relieving body pain. The disadvantage of memory foam is that new products can smell. It also has thermal insulation capabilities, so you may feel hotter.
Natural latex also has the effect of dispersing body pressure, so it can also promote sleep and relieve pain. However, natural latex has very good breathability, making it warm in winter and cool in summer. This is the shortcoming of memory foam. Other advantages of natural latex include high comfort, long service life, and hypoallergy.
So, what are the main differences between latex mattresses and memory foam mattresses? 1. Material difference: The raw material of latex mattress is natural oak sap milk, which is foamed to produce pores. Memory mattress is also called slow rebound sponge mattress or space mattress. The raw material comes from petroleum extraction. The chemical name is polyurethane (PU), which is mainly chemically synthesized. Second, the naturalness is different: latex is natural tree sap, and memory foam is petroleum. Third, the life span is different: latex does not deform normally for 15 years, and memory foam: 2-5 After years, the place where you usually sleep will sink without rebounding; 4. The sleeping feeling is different: latex rebounds immediately, while memory foam rebounds slowly. Personal preference is different; 5. The touch is different: latex has a four-season feel The same, the fitting effect is equally good. Memory foam is hard in winter and soft in summer; 6. Different functions: The oak protein in latex can inhibit the growth of mites. Memory foam has strong shock absorption capabilities. The reason why astronauts use this is just for shock absorption and nothing else. Therefore, memory foam is suitable for decorative materials, shock-absorbing materials and sound insulation materials.
Basically, these are the differences. No need for expert recommendation, I think you will choose a natural latex mattress without any doubt. If you are still not sure, please continue reading below.
First, comfort. Natural latex is an internationally recognized high-comfort mattress material. The material is purely natural, has high resilience, and has a high degree of body fit. Movements such as turning around in bed will not be affected. His presence can be found in many high-end hotel suites around the world. Such as the Burj Hotel in Dubai. Experts here recommend choosing the Golden Oak brand that uses 100% natural latex. The latex is all imported from Thailand. Thai latex is a specialty product worldwide. Memory foam is polyurethane, a chemical material. After being made into mattresses and pillows, they are very comfortable and perfectly fit the human body. However, its slow rebound characteristics will cause the human body to be unable to turn around on the memory foam mattress. This makes it impossible to complete sleeping movements on the bed smoothly.
Second, hygienic natural latex bedding can be washed directly with water. It does not breed bacteria itself and does not provide an environment for bacteria to survive. It has obvious inhibition on bacterial microorganisms such as E. coli and mites on the bed. Killing effect, maintain a good and hygienic sleeping environment. It is more effective for people with asthma and sensitive skin. Memory foam mattresses cannot be washed. Once washed with water, the slow rebound properties will completely disappear. It is a product that you can put completely on the bed board once you buy it and never move it again.
Third, price comparison. The price of pure natural 100 latex bedding is higher than that of memory foam bedding. Both products are mid-range or above in the market.
When purchasing, if the price is exaggeratedly low, it can basically be judged that the product is selling sheep over dogs. Because the production technology of these two types of bedding is more expensive than previous products.

Question 8: Which is better, latex or memory foam? Slow rebound (memory foam) is one of the most sensational and life-changing inventions in the world. There are too many research and application examples to show that it far exceeds the Other materials will become the first choice for the replacement of software appliances in the future. It does not rely on concepts or gimmicks to gain customer love. Its rise is entirely based on its excellent performance and quick trial experience. The slow rebound products such as pillows, mattresses, cushions, sofas, etc., have been developed in a vast number of markets. Stand out from other similar products and win the crown of first place! It not only gives many users a good feeling, but also brings a lot of beneficial health help, becoming one of the main pursuits of people's future life! It also does not hinder blood circulation, is not prone to fatigue and soreness, reduces the number of unnecessary turns during sleep, and increases the time of deep sleep; it is breathable and not stuffy, and has a long service life;
Memory foam mattresses and pillows are the most popular among the public. familiar. The super pressure-reducing performance of memory foam brings many advantages to memory foam mattresses and pillows, such as improving sleep quality, protecting the spine, and relieving pain, etc. Memory foam will deform under the action of body temperature and body weight, forming a shape that conforms to the natural contours of the human body, effectively supporting the human body and dispersing body weight.
Latex generally refers to a colloidal emulsion formed by polymer particles dispersed in water. Also known as latex. It is customary to call the water dispersion of rubber particles as latex, and the water dispersion of resin particles as emulsion. Products made from latex are called latex products, such as sponges, gloves, toys, hoses, etc.
