Technology & Design
Explore the innovation behind the Platinum AI Master 4D+.
The Osaki Platinum AI Master 4D+ massage chair blends precision and comfort for a deeply effective massage treatment. Two exclusive over-the-shoulder massage nodes tackle neck and shoulder tightness, while 4D rollers work their way down to your glutes. In Health Pro mode, AI technology analyzes your body, identifies tension, and generates a personalized massage that provides relief where you need it most. Enjoy calf and foot rollers, 16 auto programs, Zero Gravity recline, and soothing back and foot heat therapy. Plus, upgrade your relaxation with wireless charging, immersive Bluetooth sound, a sleek touchscreen tablet, hands-free Alexa voice control, and smartphone app integration.
Experience innovative neck and shoulder relief with the Master. Its two shoulder nodes, equipped with 20 airbags, provide upper body compression therapy that replicates the touch of real hands. Adjust the massage nodes up or down to find your perfect pressure. Need extra attention on one shoulder? Dial up the intensity for deeper relief where you need it most.
As the airbags apply downward pressure to your upper shoulders, a specialized mechanism replicates the natural movement of a human thumb along the back and sides of your neck.
The Master goes beyond a shoulder massage. Its 4D rollers move with lifelike precision, adapting speed and pressure to mimic human hands. Choose from four levels of 4D roller intensity.
The 4D rollers span a 53″ SL-Track rail made of laser-crafted steel. This design allows extended roller coverage, from your neck all the way down to your buttocks.
Before your massage begins, the 4D rollers and shoulder system analyze your body to target the right areas.
Health Pro mode uses AI to detect tension and fatigue. Simply place your thumb on the ache sensor during the analysis, and the tablet will display a color-coded representation of where tension is found. The Master then generates a personalized massage focused on your needs.
Designed for deep relaxation, the NASA-inspired Zero Gravity position reduces joint pressure and amplifies the massage intensity. Feel weightless as your body sinks into pure comfort. With the Master’s space saving technology, you only need three inches of clearance from the wall.
The Master’s heating coils deliver soothing warmth to your lower back and feet, easing soreness and tension. The two heating zones can be activated separately.
The Master’s 46 airbag cells work alongside the 4D rollers to provide a full-body pampering. The airbags gently compress and release, replicating the hands of a massage therapist working across your entire body. Airbags massage your waist, arms & hands, calves, feet, and over your shoulders. The airbag intensity can be adjusted up to five levels.
The calf airbags rotate in a circular motion, applying a deep-kneading action that refreshes and revitalizes your legs.
The Master is equipped with three reflexology ridges that activate your feet’s acupuncture points. Meanwhile, the powerful combination of calf rollers and airbags work in harmony. The footrest is fully enclosed for a total foot massage experience. The footrest will fit up to a men’s size 13.
Treat yourself to 16 expertly crafted massage routines. Each program offers a distinct blend of techniques and targeted chair movements.
Choose from three dedicated Neck & Shoulder programs, including Slight, Focus, and Shoulder Concentrated. Choose from four dedicated Lower Back programs, including Comfort, Recovery, Deep Tissue I, and Deep Tissue II.
Build a custom massage routine in manual mode. Choose from up to six roller techniques, activate airbags, spot-treat, and fine-tune the roller and shoulder system.
Operate the Master with Alexa-enabled devices or the Alexa app. With over 35 voice commands, adjusting your massage is as easy as speaking.
Control the Master through its app, available on the Apple App Store and Google Play Store. Simply sync the massage chair with Alexa to get started.
Keep your smartphone charged via the wireless pad or USB port.
Enjoy your favorite songs or podcasts with the Master’s premium audio system. The Bluetooth-compatible speakers are mounted atop the chair for an immersive sound experience.
Melt away stress, elevate your energy levels, and boost your oxygen intake with the Master’s negative air ionization therapy.
A pillow cushion can be attached to the backrest for added back support and to soften the 4D roller pressure. When not in use, fasten it to the magnetic holder on the chair’s side.
The footrest automatically extends up to eight inches and then retracts inward to match your leg length.
Use the side control panel on the armrest to make rapid adjustments.
The Master’s touchscreen tablet is mounted to a versatile, swiveling arm. Easily choose your favorite auto programs, modify the roller and airbag pressure, adjust the recline, and more.

What Customers Say
The AI-powered body scanning on the Platinum AI Master is genuinely impressive. It maps my frame with precision and adjusts the rollers accordingly - the massage feels custom-tailored every single time. The 4D+ mechanism adds a depth of pressure that I haven't experienced on any other chair. Premium in every sense.
San Jose, CA
This chair looks and feels like it belongs in a high-end spa. The upholstery is buttery soft, the mechanical movements are smooth and quiet, and the massage programs are incredibly varied. The heat therapy along the back is evenly distributed and warms up quickly. OSIM pricing was the best I found anywhere.
Scottsdale, AZ
Herniated disc in L4-L5 has plagued me for years. The AI Master 4D+ targets my lower back with a precision that generic chairs can't match. The zero gravity position decompresses my spine beautifully. After three months of daily use, my pain levels have gone from a 7 to a 3. Worth every cent.
Dallas, TX
I do yoga three times a week and the AI Master's stretch program is the perfect complement. The airbag-driven stretching combined with the roller movement opens up my spine and hips in ways that floor stretching alone can't achieve. My flexibility has noticeably improved. This is a serious wellness tool.
Seattle, WA
The Platinum AI Master feels like Osaki's flagship for good reason - the build quality, the massage technology, the materials - everything is a step above. OSIM guided me through the decision process, explained the differences between models clearly, and the in-home delivery team was professional and thorough. Couldn't ask for more.
Minneapolis, MN
The Platinum AI Master 4D+ scans my body with uncanny accuracy and delivers a massage that feels personally choreographed. The 4D rollers adjust speed and depth throughout the session, creating natural rhythm changes that prevent the 'robotic' feeling of lesser chairs. The platinum-grade materials feel luxurious. OSIM handled everything from consultation to delivery flawlessly.
Dallas, TX
Visiting spas was my stress relief, but at $250+ per session it wasn't sustainable. The AI Master provides a comparable experience for a fraction of the long-term cost. The heated back panel, the comprehensive airbag system, and the intelligent roller positioning create a spa-quality experience every evening. My skin even looks better from the improved circulation.
Miami, FL
When you combine the zero gravity position (legs above heart) with the 4D roller work on your back, the decompression and massage work together synergistically. My spine feels three inches longer after a session. Add the heat and the airbag compression, and you have a comprehensive therapy session. Absolutely worth the investment.
Seattle, WA
We have four people in our family and each of us uses the AI Master for different reasons - my husband for his running recovery, me for my desk-job tension, our teenage son for his growing pains, and our daughter for her dance soreness. The AI scanning adjusts for each person automatically. It's the single purchase that benefits everyone.
Portland, OR
As a mechanical engineer, I appreciate the sophistication of the 4D roller mechanism. The variable speed control, the multi-axis movement, and the pressure sensors that adjust in real-time represent serious engineering achievement. Beyond my technical admiration, the chair simply delivers an excellent massage. Build quality is first-rate throughout.
