OP-4D Master

A shoulder-focused 4D chair built around Osaki's first true over-the-shoulder airbag massage, combined with AI tension detection and Alexa-based voice control for a more hands-free routine.

• Thorough Shoulder Massage: Ten synchronized airbags deliver an over-the-shoulder massage that moves like real hands.
• Muscle Tension Detection: AI-driven "Health Pro" scanning tailors the program to tension detected in your torso.
• Automatic Shoulder Adjustment: A body scan detects shoulder height and width and repositions the rollers accordingly.
• 4D Massage Mechanism: Four levels of depth and five levels of intensity, strength and speed, including spot-treatment of the back.
• SL-Track: Laser-crafted steel track reaching from the neck and shoulders down to the hamstrings.
• Zero Gravity & Space-Saving: One-stage weightless recline while sitting roughly 3 inches from the wall.
• Lumbar & Feet Heating: Heating coils warm the lower back and feet to ease soreness.
• Alexa Voice & App Control: Voice commands through Alexa plus a companion phone app.
