Nowadays, cervical spondylosis is high. To prevent cervical spondylosis, it is essential to have a healthy and comfortable sleep. Because memory pillows have unique characteristics, many consumers choose memory pillows to improve sleep, but memory pillows. A dazzling array of people, the difference between high and low. How do you know the good and bad of the memory pillow?
Here I will teach you how to identify the good and bad of the memory pillow:
First, density: density is a very important factor. Relatively speaking, the higher the density, the better the quality, but the density of memory pillows varies from 30D to 120D, and many stores have falsely reported the density. It is difficult for Amoy friends to distinguish. The easiest way is to weigh the same size of the memory pillow. Generally, the adult memory pillow is above 1KG. However, the Amoy friends should pay attention to the store's false report weight. For example, some store titles write "120D high-density memory pillow, net weight 1400g". However, it is 1.3KG in the introduction of the baby. It is really not possible to get 1.2kg. Of course, don't trust the weight blindly, because the quality is related to whether the raw materials are imported, which country is imported, the production process, the production technology level and so on.
Second, the feel: a good memory pillow pillow pinch with a hand, the feeling will be more delicate and smooth, there will be a wet feeling, just like pinching on flour balls or soup balls.
Third, the appearance of the pillow core: a good memory pillow core has a small surface gap, the memory pillow with a small gap is relatively better. The most intuitive method is to remove the inner sleeve of the pillow and check the pillow core to prevent the shop home Some "lack of arms and legs" pillows to deceive customers, some stores will sew the inner sleeve and the pillow together, so that everyone can see the pillow, such a pillow may be old, dirty, and even It is a defective product, foreign trade surplus goods and foreign trade return products due to quality problems are not the same, you must be cautious.
Fourth, the molding process: good memory pillows are mostly molded by PU shaping technology, which is better than the comfort and effect of cutting molding. There is also a good hardness of the molded pillow and the inner core. It's the same, some bad quality sides will be harder than the inner core.
5. Odor: The material of memory foam is polyurethane foam, which has a certain smell when it is produced. This is inevitable. Just like the newly bought leather shoes and clothes, the manufacturer cannot sell every product. Before you get it out, it will be ventilated, ventilated, and aired. The smell will usually disappear in 1-2 weeks. If you are not a particularly sensitive person, the pillow you bought has not retreated after one month, then you have to think about it. Do you think this will be a quality issue?
Sixth, as far as possible to buy a single pillow, because the memory pillow manufacturers are generally based on foreign trade exports, and exports are single pillows, double pillow exports are no market. A single pillow mold costs in 3000-5000 yuan / Set, due to the large number of orders, tight schedule and other cost factors, the mold of the same specification needs at least 5 sets, and the need for more than 20 sets, or even more, so manufacturers generally do not make double pillow molds, double pillows on the market. It is generally impossible to use the PU styling technology. It can be confirmed that the double integrated pillow is cut and formed, and the memory pillow of the same height may not be suitable for two people at the same time, so it is recommended that the Amoy friends buy a single pillow as much as possible.
I hope the above six points can bring you some help.
Introduction to memory foam:
Memory foam is a special temperature-sensitive foam. Originally developed by the US Space Agency (NASA) to relieve the pressure on space pilots, and experienced 83,000 tests in the Gothenburg Lillhagen hospital in Sweden for 8 years, confirming that the mattress of this material can prevent the curvature of the spine and make the blood circulation better and reduce The number of turning over; the pillow made of this material is carefully combined with mechanics, art and ergonomics. The special curvature of the neck pillow and the different heights on both sides can be adjusted freely with the height and curvature of each person's neck, which can fully support the cervical vertebra. For a more comfortable sleep.
