The track is the path along which the massage rollers run in the back of the chair. An S track follows the curved shape of the spine, while an L track also runs under the buttocks and thighs. The SL track combines both and massages from the neck to beneath the buttocks. At NAIPO, the tracks range from 80 cm to 135 cm in length.
What the track does in a massage chair
In the backrest of a massage chair sits a massage mechanism with rollers. It travels up and down on a guide. This guide is called the track. Its shape determines how closely the rollers stay to your body. Its length determines how far they reach. You notice both as soon as you sit in the chair: do the rollers stay on your back in the hollow of the lower back, or do they lose contact there?
The three designs at a glance
S track
The S track is curved like a spine seen from the side. The rollers therefore follow the natural curvature of the neck, thoracic spine and lumbar region. It ends at roughly pelvis height.
L track
The L track bends at its lower end and runs under the seat. The rollers can therefore also reach the buttocks and the backs of the thighs. Depending on the design, it runs fairly straight in the backrest.
SL track
The SL track, often also called an S+L track, combines both shapes. At the top it follows the S curve, at the bottom it runs under the seat. It therefore covers the longest distance and stays close to the body in the back. With flexible SL tracks, the path also adapts to your body shape.
Why length matters
Track length tells you how much travel the rollers have. A short track mainly massages the shoulders and back. A long track reaches beneath the buttocks and thighs. This matters especially for tall people, because the distance between shoulders and buttocks is greater. You will find tips on this in Massage chairs for tall people.
A long track alone does not make a good massage, though. It also matters how well the chair recognises your body shape. Many chairs measure your back at the start for this. How that works is explained in How does the body scan in massage chairs work?.

Track and massage technology go together
The track determines where the rollers travel. The technology determines how they work. A 2D mechanism moves the rollers up and down and sideways. With 3D and 4D, depth and rhythm are added. A long SL track with simple technology therefore feels different from a shorter track with a 4D mechanism. The difference is explained in Massage chairs: 2D, 3D or 4D.
How to check the track when you try a chair in person
- Start a programme for the whole back and notice where the rollers begin at the top and end at the bottom.
- Can you still clearly feel the rollers in your lower back, or do they become weak there?
- Do the rollers reach beneath your buttocks?
- Is the pressure on your neck pleasant or too strong?

Frequently asked questions
Is an SL track always better than an L track?
For a continuous massage from neck to buttocks, usually yes, because it follows the spine and still reaches under the seat. If you mainly want to massage your shoulders and back, a shorter track will also serve you well.
What does a flexible SL track mean?
The path is not rigid but adapts, within limits, to your body shape. As a result, the rollers stay closer to the body even with different back shapes.
How long should the track be?
There is no fixed limit. At NAIPO, most models with an SL track are between 112 cm and 135 cm. Testing it in the chair is the most reliable way to see whether the length suits your height.
