According to the survey, 70% of primary and middle school students have frequent attacks of cervical spondylosis, which all stem from the children's schoolbags. The choice of schoolbags determines the healthy growth of children in each growing period, and spine-protecting schoolbags have also become the type of schoolbag that parents choose for their children. However, with the ever-changing schoolbag trend, what kind of schoolbag is a spine-protecting schoolbag? And how to choose the right spine protection schoolbag for your child?

　　1. The aerobic shoulder strap design of the school bag

　　Whether it is a backpack or a shoulder bag, the shoulder strap of the school bag is the focus of the stress of each bag, so the choice of the shoulder strap of the school bag must be a health-conscious choice. The shoulder strap of the spine-protecting schoolbag should be made of a quilted sandwich mesh layer or neoprene, so that the shoulder strap itself does not have direct contact with the shoulder, reducing the direct pressure damage of the schoolbag to the body, and it will not be too tired for long-term carrying.

　　2. Padded compartment on the back of the bag

　　The padded compartment on the back of the spine-protecting schoolbag is generally designed with a triangular design made of sandwich nets, which are distributed in two layers above the waist and around the waist. The cushion of the schoolbag is a buffer zone between the books and the back. Long-term carrying can dissipate heat, and it also prevents the books from directly pressing on the child, which prevents the child from bending over, thus posing a hidden danger of hunchback.

　　3. The small back panel inside the schoolbag

　　There is one obvious difference between the spine protection school bag and the ordinary school bag, which is the design of the inner panel in the center of the school bag. When designing the inner panel of the schoolbag, the books are placed in the inner panel of the center of gravity, and the heavy books are placed on the back to keep the back straight and cultivate a good walking posture.
