4D massage takes everything 3D technology offers and adds a crucial upgrade: time, or variable speed control. In a 4D system, the rollers not only move up, down, left, right, and in/out, but also adjust their speed and rhythm during the session.

This makes the massage feel far more natural, as the rollers can slow down for soothing strokes or speed up for deeper kneading, closely mimicking the intuitive movements of a professional masseur. The result is a massage that feels less mechanical and more human-like.

Beyond speed variation, most 4D massage chairs also come with advanced features such as body scanning (to map the user’s frame and adjust roller paths), heat therapy for improved circulation, zero-gravity positioning to reduce spinal pressure, and smart controls like voice activation for ease of use.

In short, 4D massage doesn’t just adjust pressure, it adjusts pace, intensity, and rhythm, offering a level of personalization unmatched by earlier models.
