I measure 1,80m: the balls are going back to the sacroiliac region at the bottom of the shoulder blades. Cervical massage balls can be set on the shoulders (trapezius, angle) and / or to the base of the skull. However, they are fixed and must be moved as needed which is not a hassle. It is the only seat I tried to cover the length of my back. The shiatsu functions rolling (softer) and spot AF are similar to the models that you can try in the store (calor, scholl). Much nicer than homedics. a tip: try a model magazine (Darty, Boulanger) to see if you can stand the intensity of the massage. The fabric is velvet class. IT is very elegant. The remote control is very user friendly. (First copy received defective (rest assured, it happened to me!) But exchanged quickly and without hassle by Amazon).
