3D Rollers allow for a deeper tissue massage as the rollers not only go up and down; left and right, but also in and out.  You can now control the strength of your massage.

This was one of the most important technological improvements in the industry!

Instead of just moving left to right as the older massage chairs used to do, 3D Massage Chair rollers travel in and out giving your massage an extra dimension and intensity. The rollers can push into the user's body applying a deeper massage to your entire back, or it can retract allowing for a less intense massage – this is what makes 3D massage roller technology so great!
