In-Home Delivery and Assembly – Avg. Shipping Time 10-20 Business Days

The White Glove Delivery team consists of a two person installation team that will deliver (up to 2 flights of stairs), unpack, and install your massage chair in your room of choice. These are not professional massage chair installation experts but a furniture installation team. They may or may not have installed your massage chair model before.
Massage chairs are heavy, so make sure you have some extra help to move the boxes and help in assembly.

The Osaki OS-Pro 4D DuoMax is a premium massage chair designed to deliver a personalized, spa-level experience in the comfort of your home. With dual 4D + 3D roller technology, an innovative SL Flex Track, intelligent health detection, and a full suite of customizable programs, it goes beyond relaxation to support recovery, circulation, and overall wellness.
The Osaki OS-Pro 4D DuoMax features a dual 4D + 3D roller system that mimics human touch, allowing for adjustable depth, speed, and intensity. A body scan maps your shape for precise relief, while quad rollers target both the back and lower body simultaneously to ease tension and stress.
The DuoMax features jade-core rollers that gently warm as they move, following the natural contours of your body. This soothing blend of massage and warmth helps release stiffness and promotes deeper relaxation.
Unlike a standard L-Track that stays in a fixed L-shape, the DuoMax’s Flex Track pivots with the chair as it reclines. This flexibility allows you to achieve a more natural lie-flat position, enhancing stretching and delivering a deeper zero-gravity experience.
The 36 airbags are positioned throughout the chair, providing gentle compression to the shoulders, arms, hips, calves, and feet. Multiple intensity levels let you tailor the pressure for improved circulation, muscle relief, and total-body relaxation.
The DuoMax features a piano-style arm massager that gently cradles the forearms and hands with rhythmic pressure. By targeting arm tension, it enhances circulation and provides soothing relief.
The integrated calf rollers rotate and glide up and down to provide full coverage of the lower legs. This targeted motion improves circulation and eases muscle tension in the calves.
The leg rest of the Osaki OS-Pro 4D DuoMax rotates to mimic a kneading motion on the calves. This targeted movement relieves tightness, improves circulation, and provides deeper lower-leg relaxation.
The foot rollers are designed with ridges that stimulate key acupressure points for deeper therapeutic benefits. With two rollers per foot, they deliver a full massage from heel to toe, easing tension and improving circulation.
Inspired by NASA, the DuoMax’s Zero Gravity recline places you in a weightless position that relieves spinal pressure and enhances relaxation. Its space-saving design needs only 5.5 inches from the wall for a full recline, making it ideal for any room. Paired with the Flex Track, it delivers a true zero gravity experience that standard L-shaped tracks can’t match.
Soothing heat in the lumbar area and the heated shawl work together to relax tight muscles and ease tension throughout your body. This gentle warmth enhances circulation and deepens the overall effectiveness of your massage.
The footrest extends automatically up to 7.8 inches, adjusting to fit a wide range of user heights.
The DuoMax features a full-color touchscreen tablet with an intuitive interface, making it as simple to use as your smartphone. Available in English and Chinese.
The Osaki DuoMax uses AI-powered health detection to track metrics like heart rate, blood oxygen, circulation, and fatigue. With this data, it adapts each session to your body’s current needs for a truly personalized massage.
Choose from full-body or targeted massage programs designed for recovery, relaxation, or stretching. With the Flex Track, stretching routines feel more natural, while techniques like kneading, tapping, shiatsu, and 4D variations provide endless customization.
Convenient armrest controls let you adjust recline, zero gravity position, massage intensity, and more without reaching for the tablet. This quick access keeps you comfortable and in control throughout your session.
The DuoMax includes built-in voice control, letting you operate key functions completely hands-free. Just speak a preset command, and the chair responds instantly.
Enjoy immersive sound during your massage with the built-in Bluetooth speakers. Stream your favorite music, podcasts, or calming audio directly from your device.
The negative ion therapy is designed to help reduce stress and support improved energy and overall wellness.
Stay connected while you relax with built-in wireless charging and a USB port, keeping your devices powered throughout your massage.

The DuoMax stands out with its dual 4D massage mechanisms, flexible SL Flex Track, and AI-powered health sensors that adapt each session to your body’s needs for unmatched precision and comfort.
It uses two independent 4D roller systems that replicate human hand motions to cover both upper and lower body areas simultaneously, delivering a deeper, more lifelike full-body massage.
The SL Flex Track bends and moves with your body instead of staying fixed like a traditional L-Track. This allows better stretching, improved recline, and consistent roller contact from neck to hamstrings.
Yes, the DuoMax features soothing lumbar heat and a heated shawl that drapes over your torso, helping loosen muscles, increase circulation, and enhance the massage’s effectiveness.
Absolutely. You can save customized massage programs with your preferred intensity, focus area, and technique, allowing you to start your ideal massage with one touch.
The Osaki DuoMax uses space-saving technology, requiring only about 4 inches of wall clearance to fully recline into Zero Gravity mode.

Review topics: [].
"This is hands down one of the most advanced chairs I�ve ever used. The dual 4D rollers give incredible depth and precision, and the AI body scan is surprisingly accurate. Every program feels tailored, and the stretch routine is phenomenal."
"I deal with constant tension in my lower back from sitting all day. This chair works the exact spots that bother me most. The combination of rollers and heat provides instant relief and keeps me more comfortable throughout the week."
"We have had the chair for about a month already. With five family members. We can honestly feel a difference in our bodies. We are all different weights and height and the AI capability ensures that we all get a tailored massage based on our bodies' needs. I highly recommended this chair."
"This chair is AMAZING and so more advanced than our old chair. Great deep tissue massage that we appreciate. Many more ways to create our own massages. More Auto programs to choose from. The new setup scanning does a great job changing settings between my husband and me. Yes, it takes over a minute to scan correctly, but worth it. The new tablet controller is so easy; a big upgrade over our old chair. LOVING our nightly massages – so good."
"The dual track system blows away single track systems.... imagine twice the function of single track chairs. This massage chair is used every day. The lower track is great for anyone with Siatic Nerve and/or "Glute" issues."
"I suffer with daily chronic pain from having Sensory Neuropathy. There is no cure for my neuropathy I can only try to manage pain that continues to get worse. I have chronic spasms everywhere, especially in my SI/piriformis muscles & this is the only massage chair I've had that gets deep into those spots. It has heat in the back & legs. And the stretching capability is amazing. I am so thankful for this chair-it makes me get tears in my eyes, it means the world to me. I really don't know how I'd get through my days without it. I sit in it multiple times everyday. "
"From the moment you sit down, you know this isn't an ordinary massage chair. The dual 4D mechanism mimics the hands of a skilled therapist with stunning precision, delivering deep, personalized relief to both the upper and lower body simultaneously. The way it adapts to your body's curves and tension points feels intuitive and smart, thanks to its AI-powered scanning system."
"Bought this a month ago. It hits spots I didn't even know existed! Best chair I have ever relaxed in!! I get in it every evening before bed and my stiff neck has near gone completely away. And the legs, ahhhhhh, feels like there are real fingers in there!!! LOVE THIS CHAIR, RECOMMEND HIGHLY, AND WOULD BUY AGAIN!!!!"
"I never write reviews for anything, but this massage chair is so good, I have to say it, I am very satisfied with it in all aspects, finally I have a massage chair that I really love!"
"I love how I can adjust roller depth, speed, airbag intensity, and even the timing. Whether I want light back relief or full deep tissue work, it lets me set exactly what my body needs that day."
