  • Helps customize massage placement based on body contours.
  • Supports more accurate contact around key massage areas.
  • Useful for users who want a more personalized massage experience.

  • Designed to follow the shape of the back more naturally.
  • Extends massage coverage beyond the upper back.
  • Works with the dual mechanism design for more complete body coverage.
