Sorry slips continues something when you can massage the cervical area will.So I put under the massage cushion a good sofa cushions, which holds the massage pillow top, if I want to do this while seated massage. One can for neck massage course lie with the pillows also.
The infrared heat is, however, hardly noticeable, but I am very pleased with the relaxation after the 15 Minuten.Anfangs you can if you let the pillow run too long get some soreness.
