Sanitary, clean and non-toxic. In this regard, modern polymer pillows such as memory pillows and latex pillows have a good performance. Although they are all chemically synthesized, they have passed the detection of harmful substances, and the fact that hundreds of millions of people use them proves that they are really sanitary and safe. Compared with ordinary down and cotton, it is easy to breed mites and plant fibers are easy to mildew. These microorganisms are not good for the skin.
In terms of good sleep, soft pillows generally sleep better, but some soft pillows are too warm and very hot, which is not conducive to brain cooling, and it is difficult to enter deep sleep, such as down pillows and cotton pillows. In contrast, memory pillows and high-density latex pillows have moderate thermal insulation performance and better effect. TPE pillows and gel pillows are particularly cool and more suitable for indoor use in summer and hot weather.
To protect the cervical spine, first of all, we need an ergonomic curved surface shape to properly pad the cervical spine. Therefore, pillows filled with large pieces, such as buckwheat pillows, are difficult to fix in shape, have congenital defects and have poor functions. Moldable memory pillows, latex pillows and TPE pillows have leading performance, so most modern neck protection functional pillows use these materials. To protect the cervical spine, it is necessary to eliminate elasticity, and high elasticity is a taboo for bedding. Among these materials, memory pillow has the function of slow rebound, fully absorbs elasticity, and has the best mechanical properties, which is most beneficial to cervical vertebrae, followed by TPE, while latex, due to its great elasticity, can stimulate neck tension and cannot fully relax, so it is often uncomfortable to sleep for a night.
However, it is difficult to protect the neck, which needs to match the user's body shape, sleeping position, mattress and skin strength. When buying neck pillows, you must have several styles, or adjust them appropriately to find out the most comfortable style. Otherwise, the curvature, height and hardness are not suitable, which may make the cervical vertebra uncomfortable, but it will hurt in the morning.
Considering all aspects of performance, among the common pillows on the market, memory pillows should be the healthiest.
