Nowadays, many office workers face the computer all day, leading to an increase in the incidence of cervical spondylosis, especially when air conditioning is used, while using the computer, it is easy to cause cervical discomfort and even lead to cervical spondylosis. Cervical vertebrae currently have a variety of treatments. From the perspective of long-term use, cervical vertebra 3d pillows are a treatment that can be adhered to and used by patients for a long time. So how to buy cervical pillow, what are the tips for cervical pillow? Let Xiaobian share it.
1. Look at the density of cervical pillows. Density is one of the basic indicators of high-grade cervical pillows. Due to technical bottlenecks and differences in equipment, the density of polyurethane produced in domestically produced cervical vertebra 3D pillows is generally lower than 100D, while foreign cervical pillows. The height can reach 150D, and even the same density of cervical pillow products will vary greatly, mainly due to differences in formula, process and raw materials.
2. See if the cervical vertebra 3d pillow passes the security check, and the slow rebound material belongs to the chemical. It has certain harmfulness from the chemical composition. Therefore, it must control its safety index during production, and slow rebound of toxic and harmful substances. . Is it appropriate to see a cervical pillow, depends on whether his safety test indicators pass? At present, cervical pillow testing includes detection of toxic and hazardous substances and detection of pure materials.
3, look at the cervical vertebra 3d pillow rebound time, many consumers think that the longer the cervical pillow rebound time is the better, this is a misunderstanding. A good rebound time is about 3-5 seconds. Too short to achieve a slow rebound effect; too long will make the body stiff. Press the cervical pillow and test the rebound time with a stopwatch. 3-5 seconds is better.
4, look at the cervical vertebra 3d pillow feel, feel and cervical pillow density has little relationship, mainly due to the mature process of the factory, high-grade cervical pillow feel very comfortable, pinch up like the feeling of kneading dough, almost the cervical pillow slow rebound I don't feel a little worried, or I feel a little stiff. At the same time, the high-grade cervical pillow has a good temperature sensing, which will become soft and hard with temperature changes, and the handprint can be seen without putting pressure on the hand.
5, choose the brand, now there are many brands of cervical pillows on the market, I remind everyone in the brand selection, try to choose a large formal brand. This is for a certain reason, because the large-scale regular manufacturers of temperature-sensitive memory cotton materials have matured from the processing of raw materials or formulas and processes. Although the price is slightly higher, the same effect will be better and the cost performance is higher.
6. Manufacturing process, there are two manufacturing processes for slow rebound: cutting and molding. Cutting is the finished slow-recovery sponge that is bought and cut into a pillow. Because the molding is by cutting instead of the mold + additive, no other additives are added, so even the pure polyurethane density can only be 100D. Molding is made by a series of processes such as adding additives, foaming, and die pressing. The density is increased to about 150D due to the addition of other additives, including chemical additives such as foaming and softening. it is good.
