Description

technical field [0001] The invention relates to the technical field of pillow making, in particular to a height-adjustable pillow. Background technique [0002] Recently, a domestic study conducted a survey of 2,000 cervical spondylosis patients and showed that the number of adolescent cervical spondylosis patients has increased sharply, and its proportion has risen from 8.7% to 12%. Office white-collar workers, people who use computers for a long time, car drivers, people with incorrect sleeping postures, assembly line operators with fixed postures, people who play mahjong for a long time in life, watch TV, teachers and school students are also high-risk groups for cervical spondylosis. Poor sleeping posture is one of the main causes of cervical spondylosis. During sleep, because the muscles and ligaments are in an unprotected state of relaxation, an unsuitable height will cause cervical spine injuries due to the lack of protection of the cervical muscles on the cervical s...

AI Technical Summary

Problems solved by technology

The height of traditional pillows cannot be adjusted, which results in at least one sleeping position that cannot be satisfied by the height of traditional pillows

Usually, in order to solve the discomfort on the side of the neck when lying on the side, people will choose a slightly higher pillow, which causes the neck to be in a "lower head" state when lying on the back, which inadvertently aggravates the degree of cervical spondylosis

However, if the so-called "neck pillow" is used to only support the neck when lying on the back, it will not be able to support the weight of the head when lying on the side, and prone to stiff neck or problems with the side of the cervical spine
