When shopping for your massage chair, you may hear references to S-track or L-track systems. It's an important distinction, and you want to get the one that works best for you.
The "track" we're referring to is what the rollers at your back move along. Think of a massage chair track like a railroad track with the rollers moving along it like a train. "S-track" or "L-track" describes how long the track is and what parts of the body it reaches.
S-Track Massage Chairs
The S in S track stands for “sinusoidal,” which means “wave-like.” The first massage chairs had a completely straight track, but these roller tracks follow the curve of the spine, moving from the neck to the lower back.
L Track Massage Chairs
An L-track curves along the spine just like an S track, but extends further down the body. It's really nothing more than a longer S-track system. The longer section extends further down your body to reach your glutes and hamstrings.
