Osaki OS-Pro 4D+3D DuoMax SE Massage Chair, Dual Mechanism, Heated Jade Cores, Piano Key Arm Massage, SL-Flex Track

The Osaki OS-Pro 4D+4D DuoMax SE Massage Chair is a premium full-body wellness system. It's built around the Duo Mech dual mechanism, moving heated jade cores, and a flexible SL-Flex Track. Duo Mech Dual Mechanism The Duo Mech system operates two independent quad-roller assemblies at once, 8 rollers total. The upper and lower 4D mechanisms both deliver human-like movement with adjustable depth and speed. Together they provide continuous, synchronized coverage across the full back. Health Detection and Heated Rollers Intelligent HealthPro AI tracks heart rate, blood oxygen, microcirculation, and fatigue index. This data customizes your massage to your body's current needs. Heated jade cores glide along your body's contours, delivering warmth at the same point as the massage pressure. Piano Key Arm Massage The piano key arm massage gently cradles your arms in a rhythmic, soothing motion. It targets forearm and wrist tension, an area most chairs overlook. You can toggle it independently in both auto and manual modes. SL-Flex Track and Zero Gravity The SL-Flex Track maintains a fixed angle relative to the backrest at every recline position. It delivers soothing relief from the neck and shoulders down to the hamstrings. Zero gravity reclining, inspired by NASA, offers a weightless position that relieves body pressure. Programs and Calf Care 20 auto programs and 11 manual massage styles give you extensive customization. Innovative calf rollers rotate and glide up and down for thorough lower-leg coverage. Specialized foot rollers with reflexology ridges deliver a complete heel-to-toe massage. Air Compression and Heat Therapy 38 air cells cover the shoulders, arms, hips, calves, and feet for full-body compression. Soothing heat therapy in the lower back improves circulation and eases muscle stiffness. Together they support a more complete, therapeutic session. Controls and Connectivity Smart voice control and the Osaki DuoMax app give you flexible ways to operate the chair. A side control panel offers quick physical adjustments without reaching for the touchscreen. Wireless charging, USB charging, HD Bluetooth surround speakers, and a removable headrest complete the design. Cloudy Mattress is an authorized Osaki retailer offering fast nationwide shipping on this Osaki Platinum series chair. This chair includes a 5-Year Warranty: 3 years full service and labor, plus 2 additional years parts coverage. Space-saving design needs just 5.5 inches of wall clearance for a full recline.
