Osaki Trion Flex Duo 4D+3D

The Trion Flex Duo stands out by giving the lower body as much attention as the back — its signature "walking" mechanism moves the legs in a scissor-like motion to mimic natural walking and stretch the hips and hamstrings. It pairs that with real-time health monitoring and hands-free voice control for a chair that adapts to the user automatically.

• Walking Technology: A scissor-action leg mechanism replicates a walking stride to stretch the lower back, glutes, hamstrings, and knees.
• Duo Mech 4D+3D Mechanism: A 4D roller system works the upper back with adjustable depth and rhythm while a separate 3D mechanism handles steady, deep pressure on the glutes and upper hamstrings simultaneously.
• Intelligent Health Detection: Built-in sensors track heart rate, blood oxygen, microcirculation, and a fatigue index, and feed that data into a personalized massage.
• Smart Voice Control: A wake phrase ("Hey Alice") lets users trigger preset massage commands hands-free.
• Self-Adaptive Flexible SL-Track: The track extends as the chair reclines, deepening the stretch from neck and shoulders down through the spine, hips, and thighs.
• 50-Cell Air Compression: A dense airbag layout delivers full-body compression therapy for relaxation and recovery.
• Heated Foot Rollers: A 3-roller foot system runs heel-to-ball massage with three heat settings on the middle rollers.
• Automatic Extendable Footrest: Extends up to about 6 inches to accommodate different user heights.
