How about Kang physiotherapy bed? Or recommend me some physical therapy beds other than Kang Jianyi.

Kang is a jade physiotherapy bed, which is different from ordinary physiotherapy bed. Kangjianyi physiotherapy bed is made of natural jade and heating system, which emits far infrared rays after heating, and can be used for spinal correction, hot massage and warm magnetic therapy. Generally, the physical therapy bed is only heated by infrared rays, but it is comfortable to sleep and has little effect.
