{"product_id":"osaki-os-pro-4d-4d-duomax-se-massage-chair","title":"Osaki OS-Pro 4D+4D DuoMax SE Massage Chair","description":"\u003cp\u003eThe \u003cstrong\u003eOsaki OS-Pro 4D+4D DuoMax SE Massage Chair\u003c\/strong\u003e is a premium dual-mechanism chair built for people who want simultaneous upper- and lower-body roller work instead of waiting for one massage mechanism to travel from one area to another. Two independent 4D mechanisms create an eight-roller track massage, while the SL Flex Track, calf rollers, foot rollers, heat, and 38 air cells extend the massage beyond the back.\u003c\/p\u003e\n\n\u003cp\u003eThe hardware backs up the flagship positioning: dual 4D+4D mechanisms, 20 automatic programs, 11 massage styles, intelligent health detection, zero-gravity reclining, a 7.8-inch automatic footrest extension, and a 330 lb maximum user weight. Osaki includes a 5-year warranty consisting of 3 years of full service plus 2 additional years of parts coverage.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the 4D+4D Duo Mechanism Matters\u003c\/h2\u003e\n\n\u003cp\u003eThe defining feature of the DuoMax SE is its \u003cstrong\u003eDuo Mech 4D+4D massage system\u003c\/strong\u003e. Instead of a single roller carriage covering the entire back one section at a time, the chair uses two 4D mechanisms that can work different areas at the same time. The rollers adjust massage depth and speed to create a more targeted, human-like massage rhythm across the upper and lower body.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0640\/6766\/6172\/files\/osaki-duomax-se-full-body-massage-chair-front.jpg?v=1790888579\" alt=\"Front view of Osaki DuoMax SE showing full-body massage zones and leg massagers\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch2\u003eSL Flex Track for Coverage and Stretching\u003c\/h2\u003e\n\n\u003cp\u003eThe DuoMax SE uses an SL Flex Track designed to follow the spine while also changing its angle with the backrest. That flexibility allows the roller system to maintain coverage from the neck and shoulders through the lower back and toward the hamstrings while giving the chair more freedom to open the body during recline and stretching programs.\u003c\/p\u003e\n\n\u003ch2\u003eIntelligent Health Detection\u003c\/h2\u003e\n\n\u003cp\u003eOsaki's integrated health-detection system tracks readings including heart rate, blood oxygen level, microcirculation, and fatigue index. The chair uses that information as part of its personalized massage experience. These readings are wellness features of the massage chair and should not be treated as a substitute for medical evaluation or diagnostic equipment.\u003c\/p\u003e\n\n\u003ch2\u003eLower-Body Massage Goes Beyond Air Compression\u003c\/h2\u003e\n\n\u003cp\u003eThe DuoMax SE gives the calves and feet dedicated mechanical massage rather than relying only on airbags. Vertical calf rollers move through the lower legs while air compression adds surrounding pressure. Under the feet, two specialized rollers per foot use reflexology-style ridges to work from heel to toe.\u003c\/p\u003e\n\n\u003cp\u003eThe automatic footrest can extend up to 7.8 inches to accommodate different leg lengths.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0640\/6766\/6172\/files\/osaki-duomax-se-calf-foot-massage.jpg?v=1790888589\" alt=\"Osaki DuoMax SE extendable calf and foot massage ottoman\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch2\u003ePiano-Key Arm Massage and 38 Air Cells\u003c\/h2\u003e\n\n\u003cp\u003eAir compression covers the shoulders, arms, hips, calves, and feet through 38 air cells. The arm section also uses Osaki's piano-key massage design to create more active compression through the hands and forearms than a basic squeeze-and-release arm airbag system.\u003c\/p\u003e\n\n\u003ch2\u003eTwo Heating Cores Plus Lower-Back Heat\u003c\/h2\u003e\n\n\u003cp\u003eTwo heated jade cores move with the massage system to combine roller pressure with targeted warmth. The chair also provides lower-back heat, with Osaki listing the heating-pad range at approximately 75–83°F.\u003c\/p\u003e\n\n\u003ch2\u003eZero Gravity Without Requiring a Large Wall Gap\u003c\/h2\u003e\n\n\u003cp\u003eZero-gravity reclining redistributes body pressure while the massage mechanisms work. Osaki's space-saving design requires approximately 5.5 inches of wall clearance for a full recline, helping a large premium chair fit more efficiently into the room.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0640\/6766\/6172\/files\/osaki-duomax-se-zero-gravity-recline.jpg?v=1790888584\" alt=\"Osaki DuoMax SE massage chair reclined in zero gravity position\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch2\u003e20 Automatic Programs and 11 Massage Styles\u003c\/h2\u003e\n\n\u003cp\u003eThe DuoMax SE includes 20 automatic massage programs for different routines and focus areas, plus 11 massage styles for more manual control.
