SL-Track Technology

An SL-track massage chair uses an extended massage track designed to follow the natural curve of the spine while continuing towards the seat and lower-body area.

The term combines characteristics of S-track and L-track systems, providing broader massage coverage than a traditional back-only track.

SL-track technology is commonly found in advanced full-body massage chairs and may be combined with 4D rollers, body scanning, zero gravity and air compression.

Understanding the massage track is important when comparing chairs because it determines where the roller mechanism can travel.
