Problems solved by technology

[0003] The disadvantage of the current technology is: if a person’s back wants to stick to the back of the chair, he can only change the position of the buttocks sitting on the seat surface of the chair. It requires the person to adapt to the chair, not the chair to adapt to the person. The weight basically depends on the load of the lumbar spine, and the use effect is poor
