SL-Track Massage Chairs
SL-Track (sometimes referred to as L-Track) is the latest advancement in massage chair technology. What is SL-Track? It simply means the backrest rollers massage a larger surface area than its predecessor, S-Track. An S-Track's roller system massages from the neck down to the lower back, while an SL-Track extends beyond that, sliding underneath the chair's seat to target the buttocks and even the upper hamstring muscles. Most SL-Track massage chairs feature a roller length ranging from 40 to 53 inches, while an S-Track chair typically offers a massage length of under 31 inches. That's up to 43% more roller coverage! SL-Track can be especially powerful for users with lower back, buttocks, sciatic, or piriformis issues.
