Top Features of the Osaki Grand Duo

Advanced AI Sensing Technology

The Osaki Grand Duo integrates an intelligent AI health sensor that carefully monitors the tension throughout your back.

Located at the front of the armrest, the fingertip sensor collects real-time data to identify areas needing the most attention.

From this information, the chair automatically selects the most effective massage program from its 41 preset options.  Each session is carefully personalized, ensuring that targeted areas receive the right level of care.

By combining technology with precision, the chair offers a deeply tailored massage experience that melts away stress while delivering a sense of balance and relaxation with every movement.
