As an office worker working in thousands of cities, it is inevitable to face the computer all day, so I just want to lie on the sofa when I go home. It would be great if someone came to massage at this time, so many people will want to buy a massage chair to go home. I am no exception. OTO and Aosheng massage chairs are really expensive, tens of thousands of dollars at a time, and the cheaper ones cost 6700 yuan, which is really a big expense. In fact, in the final analysis, the function of massage chair is to massage the body. No matter which brand of massage chair has some common functions, such as kneading, beating, hot compress, lacing, rocking and so on. The principle of massage chair is to use mechanical rolling and squeezing to dredge meridians and make blood circulate, so you can feel the relaxation of muscles and the elimination of fatigue after massage. The massage chair I bought is from Ding Hong, and its movement is 3D. Considering that the elderly are afraid of cold and have the function of waist heating, it is very good to use it for 20 to 30 minutes every night to completely relax their bodies.
