9 Breakthrough Functions

Domino Dynamic Lumbar Support

This is Sihoo's invention, and it is also a genius idea.

The three variables that affect comfort and health, horizontal, vertical, and vertical, are designed into three modules and integrated into a lumbar pillow.

Whether the user is sitting upright or lying back, the lumbar support can make corresponding changes in strength and position, truly protecting the waist like a shadow.
