Osaki Platinum AI Master 4D+

Osaki 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.

Exclusive Over the Shoulder Massage

Exclusive Over the Shoulder Massage

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.

Realistic Thumb Movement

Realistic Thumb Movement

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.

4D Massage Mechanism

4D Massage Mechanism

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.

SL-Track

SL-Track

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.

Body Scanning Technology

Body Scanning Technology

Before your massage begins, the 4D rollers and shoulder system analyze your body to target the right areas.

AI Muscle Tension Detection

AI Muscle Tension Detection

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.

Zero Gravity with Space Saving

Zero Gravity with Space Saving

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.

Back & Feet Heat Therapy

Back & Feet Heat Therapy

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.

Full Body Airbag Therapy

Full Body Airbag Therapy

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.

Calf Kneading & Oscillation

Calf Kneading & Oscillation

The calf airbags rotate in a circular motion, applying a deep-kneading action that refreshes and revitalizes your legs.

Calf & Foot Rollers

Calf & Foot Rollers

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.

AI body scanning is the real deal

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.

Luxury meets therapy

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.

Top-tier massage for chronic back pain

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.

The stretch programs are next level

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.

Flagship quality, impeccable service

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.

AI-powered precision is unmatched

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.

Luxury wellness at home

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.

The zero gravity + 4D combo is magic

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.

Whole family benefits

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.

Engineer impressed by the technology

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.
