A 4D mechanism works the back, varying speed, depth, and rhythm along the upper portion of an SL-shaped track, while a separate 3D mechanism works the glutes and hamstrings at the lower end of the track with a steady kneading motion. Because the two run at the same time, the back and lower body receive massage simultaneously rather than waiting for a single roller to travel between them. A body scan measures shoulder height and posture before each session and positions the rollers for users from 5 feet 2 to 6 feet 4.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTwenty-six air cells at the shoulders, arms, hips, calves, and feet apply compression in coordination with the rollers. The calf section uses eight of those cells for deep kneading, the foot section combines rollers with memory foam kneading that reaches the Achilles tendon, and acupressure nodes in the armrests align with the reflexology points of the palms. Carbon fiber heating warms three zones: the lumbar region, the seat, and the calves.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSixteen auto programs cover full-body routines, deep tissue, stretching, and targeted care, and seven manual programs apply individual techniques to a chosen area. A sensor in the left armrest reads heart rate, blood oxygen, heart rate variability, and a fatigue index at the start of a session and adjusts the program to the reading; results can be reviewed in the Osaki app. Zero-gravity recline raises the legs to heart level, a space-saving track lets the chair recline fully with 5.9 inches of clearance behind it, and the footrest extends up to 10 inches to match leg length.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eControls are on a 7-inch touchscreen tablet, a quick-access panel on the side of the chair for adjustments mid-session, and built-in voice commands. The chair includes Bluetooth speakers, a wireless phone charging pad, a USB port, seven-color LED lighting, a removable pillow headrest, and wood-grain armrest panels. Osaki's quiet-motor design keeps operating noise low. Upholstery is available in black, brown, or taupe.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAuto programs (16): including Deep Tissue, Thai Stretch, Sweet Dreams, and Revitalize.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eManual techniques (7): including kneading, tapping, shiatsu, clapping, rolling, and scraping.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eMassage system:\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eDual mechanism: 4D rollers for the back, 3D rollers for glutes and hamstrings\u003c\/li\u003e\n\u003cli\u003eSL-track, neck to hamstrings\u003c\/li\u003e\n\u003cli\u003e26 air cells: shoulders, arms, hips, calves, feet\u003c\/li\u003e\n\u003cli\u003eBody scan with shoulder width adjustment\u003c\/li\u003e\n\u003cli\u003eAdjustable roller speed, width, and strength\u003c\/li\u003e\n\u003cli\u003eCarbon fiber heat: lumbar, seat, calves\u003c\/li\u003e\n\u003cli\u003e8-cell kneading calf massage\u003c\/li\u003e\n\u003cli\u003eFoot rollers with memory foam kneading, including Achilles\u003c\/li\u003e\n\u003cli\u003eHand reflexology nodes in armrests\u003c\/li\u003e\n\u003cli\u003eMotorized extendable footrest, up to 10 in (7.5 in foot plus 2.5 in calf)\u003c\/li\u003e\n\u003cli\u003eZero-gravity recline\u003c\/li\u003e\n\u003cli\u003eSession timer: 5 to 30 minutes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eHealth sensing:\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eArmrest sensor reads heart rate, blood oxygen, HRV, and fatigue index\u003c\/li\u003e\n\u003cli\u003eProgram adjusts to the reading\u003c\/li\u003e\n\u003cli\u003eReadings viewable in the Osaki app\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eControls and features:\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e7 in touchscreen tablet remote\u003c\/li\u003e\n\u003cli\u003eSide quick-control panel\u003c\/li\u003e\n\u003cli\u003eVoice control\u003c\/li\u003e\n\u003cli\u003eBluetooth speakers\u003c\/li\u003e\n\u003cli\u003eWireless phone charging pad\u003c\/li\u003e\n\u003cli\u003eUSB port\u003c\/li\u003e\n\u003cli\u003e7-color LED lighting\u003c\/li\u003e\n\u003cli\u003eRemovable pillow headrest\u003c\/li\u003e\n\u003cli\u003eWood-grain armrest panels\u003c\/li\u003e\n\u003cli\u003eColors: black, brown, taupe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eFit and installation:\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eUser height: 5 ft 2 in to 6 ft 4 in\u003c\/li\u003e\n\u003cli\u003eWeight capacity: 270 lbs\u003c\/li\u003e\n\u003cli\u003eWall clearance: 5.9 in\u003c\/li\u003e\n\u003cli\u003eMinimum door width: 31.5 in\u003c\/li\u003e\n\u003cli\u003ePower: 110 to 120V, 50\/60 Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eDimensions and weight:\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eUpright: 31.5 in W x 58.5 in L x 47 in H\u003c\/li\u003e\n\u003cli\u003eReclined: 31.5 in W x 79 in L x 37 in H\u003c\/li\u003e\n\u003cli\u003eChair weight: 273 lbs\u003c\/li\u003e\n\u003cli\u003eShipping weight: 330 lbs\u003c\/li\u003e\n\u003cli\u003eBox: 33.5 in W x 50.8 in L x 57.9 in H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eWarranty: 3-year limited warranty covering parts, labor, and frame.
