The robotic fingers press the area to either side of your back which has a similar sensation to manual therapy. The fingers focus on the centre of the back, sometimes rocking you from side-to-side as they push and hold to alleviate tension.
The fingers stimulate your neck, upper back, lower back and now shoulder-blades (wing-treatment) depending on what setting you choose.
It is so relaxing that users often fall asleep(!), which helps to further relieve tension and stress.
