Osaki AI Vivo 4D+2D Massage Chair
Dual-mechanism massage with AI-guided personalization and extended full-body coverage
The Osaki AI Vivo 4D+2D is designed for customers who want a more advanced massage chair with two dedicated roller mechanisms. A 4D mechanism works across the neck, shoulders, and back, while a separate 2D mechanism extends massage coverage through the glutes and upper hamstrings.
With AI-assisted program selection, a flexible SL-Track, arm rollers, calf kneading, specialized foot rollers, lumbar heat, Zero Gravity recline, and modern controls, the AI Vivo delivers a more complete and customizable massage experience at home.
Best for
Users who want a premium dual-mechanism massage chair with strong back coverage, dedicated glute massage, lower-body features, and intelligent controls for a more personalized daily session.
Massage feel
The 4D upper mechanism can vary depth, speed, and rhythm, while the separate 2D lower mechanism provides steady coverage through the glutes and upper hamstrings.
Room fit
The AI Vivo is a large, heavy chair with a space-saving recline design. Measure the room, doorway, hallway, stairs, and delivery path before ordering.
Key massage features
These are the main AI Vivo features most customers should understand before choosing this chair.
AI-Assisted Massage Personalization
The AI Vivo uses a built-in fingertip sensor to collect wellness-related data and help select a massage program suited to the current session. The system is designed to make program selection easier and more personalized.
- Uses sensor readings such as heart rate, blood oxygen, microcirculation, and fatigue-related data.
- Helps the chair choose a massage program based on the information collected.
- Designed for massage personalization only and is not a medical diagnostic device.
Duo Mech 4D + 2D Massage System
The AI Vivo combines two separate massage mechanisms to cover more of the body at the same time. The upper 4D mechanism targets the neck, shoulders, and back, while the lower 2D mechanism works through the glutes and upper hamstrings.
- 4D upper mechanism provides adjustable depth, rhythm, and intensity.
- 2D lower mechanism adds dedicated massage below the main back track.
- Designed to provide broader coverage than a conventional single-mechanism chair.
Self-Adaptive Flexible SL-Track
The flexible SL-Track follows the natural curve of the spine and adapts as the chair reclines. This helps maintain roller contact from the neck and shoulders through the back, hips, and upper thighs.
- Combines spinal contouring with extended lower-body coverage.
- Supports stretching programs by adapting during recline.
- Works with body scanning to improve roller alignment for different users.
Three Dedicated Arm Rollers
Unlike armrests that rely only on air compression, the AI Vivo includes three rollers designed to knead and press along the arms. This adds a more focused mechanical massage to an area often treated only with airbags.
- Targets muscles and pressure points along the arms.
- Adds rolling and kneading contact inside the arm massage area.
- Complements the chair’s full-body roller and compression system.
Zero Gravity with Space-Saving Recline
The Zero Gravity position reclines the body into a more supported angle during massage. The chair can fully recline while positioned approximately two inches from the wall, helping reduce the rear clearance normally required by a large massage chair.
- Creates a more relaxed reclined position during selected sessions.
- Requires approximately 2 inches of wall clearance for full recline.
- Always confirm room dimensions and the final installation position before delivery.
Soothing Lumbar Heat
Carbon-fiber heating pads add gentle warmth to the lower-back area during selected massage sessions. The warmth is designed to complement the roller massage and create a more comfortable relaxation experience.
- Targets the lumbar region with mild, steady warmth.
- Manufacturer-listed operating range is approximately 75–83°F.
- Designed for comfort and should not be treated as medical heat therapy.
Calf Kneading and Three Foot Rollers
The lower-body system combines rotating calf kneading, air compression, and three specialized foot rollers. Together, these features provide focused contact from the calves through the heels and soles of the feet.
- Rotating kneading and rubbing action surrounds the calves.
- Three foot rollers cover the heel, arch, and front of the sole.
- Air compression helps keep the feet positioned over the roller system.
Additional comfort and control features
These supporting features make the AI Vivo easier to operate and more adaptable for different users and massage preferences.
12 Auto Programs
Automatic programs include Yoga Stretch, Neck & Shoulder, Shiatsu, Waist & Buttock, Tranquil, Back & Spine, Relax, Thai, Gentle, Traditional, Soothing, and Gentle Press.
6 Manual Techniques
Manual choices include Kneading, Sync, Knocking, Tapping, Shiatsu, and 4D Shiatsu for more direct control over the massage style.
Intelligent Voice Control
Selected chair functions can be operated with supported voice commands listed in the owner’s manual.
Touchscreen Remote
The touchscreen controller provides access to automatic programs, manual adjustments, recline settings, and comfort features.
Automatic Footrest Extension
The footrest can extend up to 6 inches and uses body scanning to help accommodate users up to approximately 6'4".
Convenient Side Controls
Frequently used settings can be adjusted from controls positioned near the armrest without opening the full remote menu.
Wireless Phone Charger
A built-in wireless charging area lets compatible phones recharge while the chair is in use.
Bluetooth HD Speakers
Built-in speakers allow users to play music, podcasts, audiobooks, or relaxation audio from a compatible device.
USB Charging Port
The integrated USB port offers another convenient way to keep compatible devices powered during a massage session.
Before you choose the AI Vivo
The AI Vivo is a large premium chair delivered in multiple boxes. Before ordering, confirm the chair dimensions, minimum doorway width, wall clearance, delivery path, warranty coverage, and delivery service with Tittac.
- Measure the room and allow space for the fully reclined length.
- Check the narrowest doorway, hallway, stairway, and turn along the delivery path.
- Confirm whether partial assembly or side-panel removal is needed for delivery.
- Ask Tittac about delivery, setup, warranty, and return details for your location.
Osaki AI Vivo 4D+2D FAQ
What does 4D+2D mean on the Osaki AI Vivo?
The chair uses two separate mechanisms. A 4D mechanism massages the neck, shoulders, and back, while a 2D mechanism provides additional coverage through the glutes and upper hamstrings.
Does the AI Vivo diagnose medical conditions?
No. The built-in sensor is designed to support massage personalization. It is not a medical device and should not be used to diagnose, monitor, or treat a health condition.
How much wall clearance does the AI Vivo need?
The product information lists approximately 2 inches of wall clearance for full recline. You should still measure the complete placement area before ordering.
What is the maximum user height?
The automatic footrest can extend up to 6 inches, and the product information states that the chair can accommodate users up to approximately 6'4". Comfort can still vary by body proportions.
How wide must the doorway be?
The listed minimum doorway width is 30.5 inches. Because the chair is large and shipped in multiple boxes, measure the complete delivery path and confirm installation requirements with Tittac before ordering.
