For us, sleep is very important. Although sleep seems to be a very common thing, how many people suffer from various diseases due to poor sleep. So one of the key factors that affect our sleep is the choice of our mattresses. Today we will make a detailed evaluation for the popular silicone mattresses in recent years, so that you can have a clearer understanding of silicone mattresses.
Advantages and disadvantages of silicone mattress
Advantages: because of the excellent shock absorption effect of silica gel, which is also the characteristic of silica gel, the silica gel mattress will automatically adjust to the appropriate soft hardness of different human bodies, so that we can lie on it to release the pressure of the body, while the silica gel mattress can support or support different parts of our body, which can eliminate the waist Acid back pain, promote the role of smooth blood circulation.
In different temperatures, the soft and hardness of silica gel mattress will change with the temperature. Generally speaking, the hot part will be soft and the cold part will be hard. At present, the protrusion of lumbar disc is not only a disease of the elderly, but also a younger one. Many 30-year-old left and right young people who go to the hospital suffer from lumbar disc, so this kind of silica gel mattress is the most suitable for patients with lumbar disc For the fit, because our waist is the concave part of the body curve, lying flat on the mattress will have a slight gap, while the silicone mattress will feel, so that this part will become hard, giving us a good support, making us very comfortable to lie down, without low back pain.
Disadvantages: the silica gel mattress is a petrochemical product in the process of production, which is made by foaming with liquid medicine. Most of the liquid medicine is imported from Japan and South Korea, so the price is relatively expensive. However, there will be some fake and shoddy products on the market, which is a lifelong regret. The life span of the silicone mattress is about 7 or 8 years. However, the soft and hard changes of the silicone mattress when we sleep on the bed are very meticulous, so it will take a lot of time to achieve the effect of health care, and it will not solve the problem of backache as the salesman said.
As for the advantages and disadvantages of silica gel mattress, we all know that if it is the silica gel material produced by regular manufacturers, it is generally the environmental protection material that has no harm to human body, but the poor silica gel is hard to say.
Silicone pillow
Silica gel pillow is a kind of pillow made of silica gel as raw material. Silicone pillow is known as gel pillow is the latest innovative products, the main material is made of slow rebound material, covered with a layer of gel, so that the body after entering sleep, have a cool feeling, its function is not to increase people's memory, but because often used pillow head will form the shape of the human head and neck.
Silica gel pillow is a transparent or milky white granular solid. It has an open porous structure, strong adsorption and can absorb many kinds of substances. If absorbing water, the moisture absorption is about 40%. Cobalt chloride is added, blue when it is dry, red after absorbing water. Renewable and reusable. Silica gel has a strong adsorption capacity and can dry human skin. Blue silica gel is toxic because it contains a small amount of cobalt chloride.
Advantage
Silicone pillows have a unique appearance, which is very obvious compared with ordinary pillows. This pillow has silica gel that looks like crystal water, but it doesn't leak like a water pillow.
2 silicone pillows provide you with the same comfortable experience as water pillows, but provide more support than water pillows.
3 because silicone pillows are made of gel foam, so you will have a very cool feeling, which will further make your sleep comfortable.
4 silicone pillow surface is specially designed, the whole sleep structure will provide good ventilation. This will help you avoid waking up in your sleep, which is quite a stimulating experience.
Although we are all sleeping, there will be different pressures that can affect us, and silicone pillows can help us relieve the pressure and not disturb your sleep.
Future market prospect
In the use process, due to the adsorption of water vapor or other organic substances in the medium, the adsorption capacity is reduced, which can be reused after regeneration. The silicone pillow made of silica gel has the health care functions of cooling, ventilation, comfort and natural massage. Very popular in the market, popular in Japan, South Korea, Europe and other countries. Silica gel pillow is mainly used for reducing blood pressure, damping, not absorbing heat, cooling, ventilating, etc. Especially suitable for summer use.
Some experts have analyzed the market share of silica gel pillows, and there is nearly 10-20 billion market space, so what is China's silica gel pillows like? Such a large market gap is a theoretical gap, or a virgin land to be developed. The answer is yes, because this market has always existed, but the silicone pillow market has not been grasped. Specifically, the silica gel pillow market can be divided into four parts: the first part is the newlywed market. With the rapid development of the national economy and the rapid improvement of people's living standards, the demand for wedding gifts in China is growing rapidly, and the wedding gift market is developing and expanding rapidly. Silica gel pillow is also one of the wedding gifts, and the sales volume of silica gel pillow is also increasing, The demand for silica gel pillow materials is also increasing; the second part is the children's market, because silica gel pillow itself is non-toxic and odorless, which is very good for children's health, and is also liked by many parents; the third part is environmentalists, who are keen on environmental protection and have strong environmental awareness in their daily life, silica gel pillow has such characteristics 。
