Osaki Virtus Duo 4D+3D

The Virtus is pitched as a dual-mechanism chair that runs 4D and 3D massage systems together, with one set of rollers on the upper back and another on the lower body working at the same time. It emphasizes a "human-like" feel through real-time adjustments in speed, rhythm, and intensity, plus AI health tracking to steer program selection.

• 4D+3D Dual Mechanism: Two independent roller systems run simultaneously — one covering the upper back, the other the glutes and hamstrings — for a more layered, two-handed-feeling massage.
• Intelligent Health Detection: Sensors track blood oxygen, heart rate, fatigue, and microcirculation and use that data to suggest a suited massage program.
• Intelligent Voice Control: Massage settings can be adjusted through spoken commands instead of the remote or touchscreen.
• Intelligent Memory Function: Up to four user profiles can be saved, each remembering program choice, intensity, roller position, air pressure, and recline angle.
• SL-Track with 3-Stage Zero Gravity: A spine-following track pairs with a NASA-inspired weightless recline to reduce spinal pressure during longer sessions.
• 30-Cell Air Compression Massage: Air cells positioned around the body add compression therapy alongside the roller massage.
• Calf-Kneading Massage: Dedicated lower-leg kneading is included to help with circulation and muscle recovery in the calves.
• Space-Saving Design: The chair slides forward as it reclines, needing only about 5 inches of wall clearance for a full recline.
