9660 Massage chair comes with new S-Track roller system. The S-Track is the shape of the human spine. The S-Track allows the rollers to move up and down the back of the user, following the curvature of the spine.
It moves more forward for the neck and low back regions of the spine, and retracts a bit in the mid back and tailbone areas of the spine. This makes for a more comfortable massage on our new 9660 chair.
