Before going to sleep, whether lying on your side or on your back, make sure to place your head in the middle of the pillow, with your neck and the pillow fitting together in a tight seam, leaving no gaps. If you wake up during sleep and feel that your sleeping posture has changed, your head is off the middle and there is a gap between your neck and the pillow, you should adjust it in time until there is no gap, i.e. your neck should fit perfectly with the high end curve of the pillow. ▼The high end of the pillow is padded on the neck to play a compulsory therapeutic role, and is also suitable for those with a wide shoulder and thick back. The low end of the pillow is suitable for regular health care preventive use, but of course the main focus is on comfort, which can be adjusted according to your own comfort in practice. ▼It may feel slightly uncomfortable when first used, but after a few days of use the discomfort will be eliminated and you will be able to sleep quickly. For the first time, please lie down and feel the curve of your neck with your hands and feel your breathing, if it is smooth, the height you are using is normal.
