What is memory foam

Memory foam, also known as slow rebound, is an open cellular structure developed in the 1960s by HEALTHMAN, a company owned by NASA. It has the characteristics of temperature sensing and decompression. It can also be called a temperature-sensitive decompression material. HEALTHMAN, an American company, used it on the space shuttle. In order to relieve the stress on the astronauts, to protect the spine of the astronauts, especially when the shuttle is returning and leaving the ground, the stress on the astronauts is the most dangerous. In order to protect the safety of astronauts, this material was invented. The biggest science in the 21st century will be life science. Space science and technology has made great contributions to the research of human life science. At the beginning of 1990s, Fagerdala company in Sweden developed again for civilian (medical) products, which were widely promoted and applied in medical first aid and monitoring system. It then spread rapidly in developed countries, especially health-conscious ones like Japan. HEALTHMAN's civilian slow rebound material is a visco-elastic material developed by NASA's Healthy Sleep Research Center. The so-called temperature sensation refers to the induction of human body temperature. Decompression is absorbing the body's stress. When the human body touches the material, the material will sense the temperature of the human body and gradually become soft, while absorbing the pressure of the human body, so as to adjust the human body to the most comfortable posture. What is shown on the mattress and pillow is that when the person lies on the mattress and pillow, the spine is the natural physiological state of s-shape bending when lying on the back, while the spine is not curved when lying on the side. At the same time, the mattress and pillow have no pressure on the human body, which is the material.

The characteristics of the mattress slow rebound memory foam mattress through the unique temperature sensing memory particles sense the body temperature, provide comfortable support hardness; At the same time, it can sense and remember the curves of the human body, and make perfect shape according to the ups and downs of the human body. It can protect the natural bending of neck, waist, hip and legs. Lie on your back or side, can make human body each part is in a state without pressure, promote blood circulation, relieve physical fatigue and soreness, avoid the traditional mattress because neck, waist overhead bending fatigue produce production and neck stiffness, the cervical spine and get complete relaxation and rest, and then reduce unnecessary for infant sleep, reduce snoring, muscle pain, etc. 1. Whether supine or lateral, can automatically shape the relief effect according to the needs of the human body, effectively dissolve the pressure of the human body to zero pressure, offset the reaction force, completely relax neck, shoulder and waist; 2. Avoid the traditional mattress to make the neck and waist overhead bending fatigue and stiff disease; 3. Do not obstruct blood circulation, not easy to produce fatigue and pain, reduce the number of unnecessary turning over during sleep, increase the time of deep sleep; 4. Excellent material selection, breathable and not stuffy, long service life;
