It has a velcro strap at the back to easily add onto chairs and based on which chair you have, you can position it to reach other parts of your body eg. Neck, shoulders, lower back etc.
The size of this massage pillow is good for compact and travel however it does limit the area it can reach and repositioning it every 5-10 minutes to let the massager reach other areas takes away from the relaxation.
It has 2 modes. Clockwise rotation and anto clockwise rotation. One of these modes also is heated too (watch attached video).
It is good though and does not fail to work, however if any problems arise, I will update this.
