Many massage chairs leave the shoulders as an afterthought. The Knot Buster puts them at the center of the experience. Ten dedicated shoulder airbags rotate and compress in a coordinated pattern that mimics the motion of a pair of skilled hands working through deep muscle tension. Proprietary fingertip massage nodes sit on each shoulder pad and apply focused thumb-like pressure directly into the trapezius. An automatic shoulder adjustment detects your exact height and width at the start of every session and repositions the entire shoulder unit to fit you without any manual tuning. The full SL-Track handles the rest of your body simultaneously so nothing gets left out.

How do the fingertip shoulder nodes work? Standard airbags apply broad, even pressure across a surface. The Knot Buster's fingertip nodes are different. They are small, rounded contact points built into each shoulder pad that concentrate force into a narrow area, the same way a thumb digs into a knot during a real massage. As the airbags compress and rotate around them, the nodes stay fixed on the trapezius and apply consistent, targeted pressure.
