Description

Technical Field

[0001] The utility model belongs to the technical field of bedding products, and in particular relates to a composite pillow with adjustable curvature at the cervical vertebrae. Background Art

[0002] Due to differences in cervical conditions between different groups of people and individuals, their comfortable sleeping angles of the cervical spine during sleep are different, and it is relatively difficult to choose a pillow product that suits the comfortable sleeping angle of their own cervical spine. There are obvious differences in sleeping comfort between the airbag pillows on the market and non-airbag pillows such as all-cotton pillows, memory foam pillows, and latex pillows. Most of the current airbag pillows are filled with various hollow air bags, and the comfort needs to be improved. Among the existing neck protection pillows, most of them achieve the neck protection function by changing the fixed shape of the pillow's neck position. It is difficult for consumers to select pillows that suit their own cervical spine conditions when purchasing. Currently, airbag pillows are mainly concentrated in the application of pillow height adjustment. There are relatively few applications that use airbags to adjust the curvature shape and height of the contact surface with the cervical spine, and the improvement is not comprehensive. At the same time, the comfort needs to be improved. Utility Model Content
