Living room chair principle

The principle of the massage chair is to imitate manual massage, but it uses mechanical rolling force and mechanical force to massage. The massage chair can perform deep massage along the spine with various massage techniques such as rocking, acupressure, pinching, and kneading according to the curve of the human body. When people sit on a massage chair and enjoy the relaxation of their whole body, it is as if someone is beating their back and rubbing their shoulders.

The upper part is not much different from the style of the general living room chair, but there is a hinge part called "single leg" under the seat surface, so the human body can rotate left and right when seated. The swivel chair did not appear very early, it was a chair that absorbed foreign styles earlier in Chinese furniture.
