The massage mat massaged vigorously in Tuina or Shiatsu style. It's good. However, in the car, the design of the mat does not work. The buttocks mat carries on too high and the vibration must be imagined. In the lumbar spine, the massage is too strong and unbearable; So I have the buttocks mat folded up (is actually not even the intention). Then I sat in the driver's seat good though and the LW.Massage was unbearable. The neck massage does not work, because for me the massage pressure points above the thoracic spine; but massaging below the neck. The mat is designed for Asians with a height of 165 cm max. When I lifted up the seat mat, the massage pressure points on the neck were a little higher; but still not enough. Absolute bad buy for me. My wife 165 cm now uses the massage mat at the desk. This works quite well. So no return.
