Unlike people in China, people in China sleep with pillows, while Americans have the habit of reading at night, so they basically use two big pillows and even put one on their feet. These habits determine that their demand for pillows is different from that of China.

Therefore, China people are used to buying pillows and choose as follows:

First, it meets the physiological needs: when lying on your back, the pillow can keep the curvature of the neck, and the edge of the pillow should be kept arc-shaped and not tilted; The height of the pillow should conform to the individual's shoulder width. When lying on your back, the pillow height should be about one punch and two fingers when lying on your side.

Height: Modern research believes that the pillow should be slightly lower than the distance from the shoulder to the ipsilateral neck. The height of the pillow is determined according to the physiological curve of the arrangement of seven cervical vertebrae in the human neck. Only by adapting to this physiological curve can the muscles, ligaments and joints of the shoulder and neck be relaxed. Too high or too low a pillow is not good for human health.

Three lengths and widths: the pillow should be longer, and the length of the pillow should be enough to sleep and turn over the back position.

The pillow is not easy to be too wide. If it is too wide, it will exceed the head and neck joints, and the muscles will be nervous easily. 15 ~ 20 cm is appropriate.

Four soft and hard: the pillow should be moderate in soft and hard and slightly elastic.
