This chair is awesome.  I would recommend to anyone suffering with pains and aching muscles.  I feel in love with it once I sat in it.  LOVE IT!! Oh my, it rolls on your feet, back and neck.  The air bags work great on the legs, waist.  The shoulder air bags need to be a little more tighter to feel any results.  O gravity just feel like you are so relaxed.  You can play your music from your Bluetooth.  One more feature that need adding is somewhere to put your drink or phone down on.  The head rest could have a little more cushion, for those who have neck issues.  I still love it!!
