[0002] Cervical spine health has become a topic of widespread concern in modern society, especially after using computers, mobile phones and other electronic devices for a long time, cervical spine problems become more prominent.

[0003] Currently, there are memory foam pillows, latex pillows, bamboo fiber pillows, etc. on the market that can adapt to the sleeper's cervical curvature. However, these pillows mainly support the sleeper's existing cervical spine according to the deformation of the support, and cannot play a role in regulation and prevention. Therefore, cervical pillows with adjustable pillow curvature have gradually appeared, such as the prior art "A Multi-curvature Cervical Adjustment Pillow" (Publication No.: CN205390924U), which provides padding at the bottom of the pillow to raise or lower the height and angle of the front and back ends of the pillow, thereby protecting and correcting the user's cervical curvature. However, the prior art still has the following technical problems:

[0004] When adjusting pillows in the prior art, it is necessary to remove the pillowcase to increase or decrease the padding under the pillow core, which makes the raising or lowering adjustment method complicated. At the same time, since the thickness of the padding is fixed, the height of raising or lowering the pillow is also fixed, which is difficult to adapt to individual differences and changes in cervical spine status, and still cannot achieve a good effect in regulating and preventing cervical spondylosis. Utility Model Content

[0005] The utility model provides an adjustable multifunctional cervical pillow, which can solve the problem that the cervical pillow in the prior art has complicated adjustment steps and cannot be adaptively adjusted according to the individual differences of users and changes in the cervical spine, resulting in poor treatment effect of cervical spondylosis.
