As a high-quality mattress material favored by developed countries, memory cotton has the characteristics of slow rebound, can effectively absorb the impact force, memory deformation, anti-bacteria and anti-mite, breathable and moisture-absorbent, and is approximately perfect as a mattress. But the word memory cotton will be strange to many people, because this is a mattress material that is not popular in the domestic market. It is not because of product quality problems and people abandoned, but because of the complex manufacturing process and cost problems of materials, many domestic manufacturers are unwilling to invest in them. But in fact, as early as 30 years ago, foreign countries have begun to popular memory cotton mattress, what is the specific memory cotton, memory cotton mattress and what performance?
What is memory cotton?
Memory cotton is an inert cotton or viscoelastic foam fabric made of polyurethane that has the ability to slowly deform and slowly return to its original shape after the force has disappeared. Originally developed by NASA to protect astronauts from harm, it was used to improve the seat of the spacecraft, and then slowly applied to the field of life, the more famous is the mattress and pillow.
Features: Significant viscoelastic characteristics, reflecting very soft material characteristics, and has a strong impact energy absorption capacity, not easy to heat
There are roughly three kinds of memory sponge: silicone memory sponge, gel memory sponge, hydrophilic sponge
Silicone memory sponge: can be made into a relatively high density of sponges, in the three materials can be the hardest; The inertia performance will change with the change of temperature, the lower the temperature, the stronger the inertia, in general, the mechanical stability is poor.
Gel memory sponge: gel memory sponge is memory cotton with the change of body temperature will have some changes, if you have a high temperature, adding gel can reduce the temperature of the body, so that bedtime is not so hot, and silicone memory sponge performance is relatively close, the difference is that its mechanical performance is not sensitive to changes in temperature, if you do not need "extra hard", can completely replace silicone memory sponge.
Hydrophilic sponge (New hybrid sponge) : Hydrophilic cotton is a hydrophilic memory cotton, also known as the second generation of memory cotton, it combines the advantages of memory cotton and latex, with hydrophilic, antibacterial, environmental protection, resilience, can sense human temperature, relax the whole body, while giving the body effective support, reduce sleep due to blood pressure caused by turning over, extend deep sleep time, improve sleep quality. It is usually soft, and the fit is the best among the three, but the disadvantage is that the tear strength is poor, and the water absorption capacity is relatively strong (its own water content is high) is not conducive to keeping fresh.
Second, how about memory cotton mattress?
Memory cotton mattress belongs to a kind of sponge mattress, mainly composed of high-density polyurethane, which can fit the body well and achieve the role of reducing body pressure. Unique pressure release shock absorption characteristics, let the partner sleep peacefully, but the permeability is not good, and not easy to heat with heat storage characteristics, lying in bed in summer is easy to heat.
Advantages:
1, low resilience, good fit
2, suction buffer
3. Quiet and silent
Cons:
1, poor air permeability
2, not easy to heat
Representative brands: Tapur, Dream Lily, Blue Box
Application scenario: Widely used in tatami, high box bed, student dormitory, rental room;
Summary: Traditional mattress materials will have a reaction force on the human body, the spine and joints are squeezed by the mattress, will feel paralyzed and sore, people will unconsciously roll over, affecting the quality of sleep. The use of memory cotton mattresses can eliminate the pressure of the human body, the mattress has no reaction to the body, people sleep on it like floating in the cloud, the whole body blood circulation is smooth, the number of turns is greatly reduced, and the quality of sleep will be improved. It is a good choice for people with soft sleep sense!
Third, memory cotton mattress brand
In recent years, memory cotton mattress, memory pillow has been recommended by many people, many people say that memory mattress can make you sleep better. So what are the current memory cotton mattress brands?
Four, memory cotton mattress and latex mattress which is good?
Memory cotton mattress and latex mattress Liu uncle has studied a lot before, to tell you about it! These two types of mattresses are soft types, and summarize the differences and advantages and disadvantages between the two.
Summary: Memory cotton and latex, both are "soft" types of mattresses, latex mattresses and memory cotton mattresses have their own characteristics, there is no best, only more suitable, after all, different people's body curves, sleeping habits, preferences are different, if you want to buy recommendations combined with their own situation to buy.
