Osaki 4D Optim

The 4D Optim shares the same 53-inch dual-rail SL-Track and 4D mechanism as the Epic LE but is positioned a step up, adding voice control as a standard highlight and a slightly refined feature set including 24 auto programs. It's marketed as a well-rounded chair combining body-scanning precision, zero gravity comfort, and integrated heat/air compression for everyday relaxation.

• Intelligent Voice Control: Hands-free spoken commands let users adjust settings without reaching for the remote.
• Dual Rail Massage System: The extended 53-inch dual guide rail carries the SL-Track from the neck and shoulders to the upper hamstrings for continuous coverage.
• 4D Massage Mechanism: A responsive roller system varies pressure and motion to feel more natural than a fixed-pattern chair.
• Body Scan System: Sensors detect the user's body contours and adjust the massage path accordingly for a more tailored fit.
• 3-Stage Zero Gravity Reclining: NASA-inspired weightless positioning is designed to reduce spinal pressure and improve circulation during the massage.
• 28-Cell Full-Body Air Massage: Airbags across the shoulders, arms, waist, legs, feet, and ankles provide adjustable compression therapy.
• Calf Roller & 3-Row Foot Roller Massage: Dedicated calf kneading pairs with three rows of foot rollers for combined lower-leg and sole massage.
• Automatic Leg Extension: The leg rest extends up to 6.5 inches on its own to fit a range of user heights.
