Experience luxury full-body therapy with synchronized dual 4D massage mechanisms, a flexible hybrid track, and intelligent AI customization designed to deliver deep therapeutic relief from neck to glutes.

Experience elevated relaxation with the Infinity Sensation 4D DualFlex Massage Chair, featuring synchronized dual-action massage and intelligent flexibility along the spine. Sensation 4D DualFlex adapts seamlessly to your body—delivering a sophisticated, full-body experience designed for recovery, restoration, and effortless relaxation. At the core of Sensation 4D DualFlex is a powerful 4D Dual Mechanism that synchronizes the movements of two massage therapists, delivering deep-tissue relief from neck to glutes with multidirectional motion and variable speed. Flex Track technology combines L-Track coverage with S-Track stretching for exceptional reach and decompression, while cutting-edge AI Technology adds unmatched customization via the robotic massage screen.

The Sensation 4D DualFlex's revolutionary 4D Dual Mechanism represents the pinnacle of massage chair innovation, synchronizing the movements of two massage therapists to deliver deep-tissue relief from neck to glutes with multidirectional motion and variable speed. Unlike single-mechanism chairs, this advanced dual-back system choreographs two individual massage mechanisms to work synergistically together, utilizing 2D, 3D, and 4D technologies in harmony for the most advanced chair massage available today.
The dual mechanism employs five distinct massage techniques—Kneading, Knocking, Tapping, Kneading & Tapping, and Shiatsu—each designed to target different types of muscle tension and therapeutic goals. With adjustable 4D intensity, variable speed control across four back zones, and the ability to assign different technique modes to upper and lower regions, the dual system delivers a massage experience that feels remarkably like having two therapists working in perfect coordination. This synchronized approach provides comprehensive therapeutic relief to both the back and gluteus region in a single, continuous session.


The Sensation 4D DualFlex features innovative Flex Track technology that combines the best of L-Track and S-Track designs, creating exceptional reach and decompression along your entire spine. The unique Flex-Track opens up upon recline while allowing the mechanism to continue down to the gluteus region, delivering superior spinal decompression and full-length neck-to-glutes massage that traditional fixed-track systems cannot achieve.
The Near-Flat Reclining Decompression Stretch guides your body into a full-body stretch, stabilizing the hips while gently elongating the spine. This advanced stretching capability addresses one of the most sought-after therapeutic benefits—spinal decompression—by creating the ideal positioning for your body to release tension and achieve true relaxation. The result is exceptional reach, comprehensive coverage, and a stretching experience that prepares your muscles for optimal therapeutic benefit throughout your entire massage session.


Your Sensation 4D DualFlex features advanced customization that delivers a real-time, personalized massage designed to relieve tension and stress. Through the Custom Program Generator, you can assign technique modes to four back zones—two upper zones for the top mechanism and two lower zones for the bottom—while adjusting 4D intensity and speed for the upper back mechanism and selecting airbag compression therapy under Air Pressure.
Cutting-edge AI Technology adds unmatched customization via the robotic massage screen, letting you select techniques, adjust 4D intensity, control speed across four regions, and fine-tune air compression. Sessions can also be personalized using the 7" Touchscreen Tablet, Intelligent Voice Command, or Quick-Access panel, putting complete control at your fingertips. This level of customization creates a massage experience that adapts in real-time to your body's needs and preferences, delivering therapeutic relief exactly where and how you need it.


Special technology within the hardware and software of the Sensation 4D DualFlex allows the chair to pinpoint your size and shape, providing a customized massage specific to you. TrueFit® Body Scanning creates a personalized therapeutic profile that ensures every technique is perfectly calibrated to your individual physique and preferences, eliminating guesswork and delivering targeted relief exactly where you need it most.
By precisely identifying your body's unique dimensions and acupressure points, the body scan ensures optimal massage targeting and intensity for your specific body type. Whether you're tall, short, or have unique body proportions, the Sensation 4D DualFlex adjusts to provide optimal therapeutic benefit every time. This personalized approach means you receive consistent, professional-grade therapy from the very first session.


Experience the freedom of flexible furniture placement with the Sensation 4D DualFlex's innovative Zero Wall Fit® technology. This space-saving design slides the chair forward when reclining, taking up less space in your room and solving one of the most common challenges with massage chairs—finding enough room in your home for full recline capability.
Traditional massage chairs without this technology must be placed several feet away from walls to accommodate full recline, consuming valuable living space. The Zero Wall Fit® system solves this by sliding the chair forward as it reclines, maintaining the proper angle for zero gravity positioning while keeping the back of the chair close to the wall. This intelligent design means you can enjoy the full therapeutic benefits of deep recline and zero gravity positioning without sacrificing valuable floor space or compromising your room's layout and aesthetics.


Experience comprehensive foot therapy with the Sensation 4D DualFlex's Dual Sole Reflexology Foot Rollers, replicating the thumb and finger technique of applying pressure to vital points on the soles of the feet, which send relief to other areas of the body. This advanced foot therapy technology delivers therapeutic relief that extends from your feet throughout your entire body via traditional reflexology pressure points.
Each foot receives individualized attention from strategically positioned rollers that target your arches, heels, and the complete sole surface, including all major reflexology zones that correspond to different organs and body systems. Combined with air cell compression that positions your feet optimally for maximum contact and therapeutic benefit, the dual sole reflexology system creates a deeply satisfying foot massage that relieves fatigue, improves circulation, reduces tension, and provides holistic wellness benefits that enhance your overall massage experience.


Take complete command of your massage experience with the Sensation 4D DualFlex's 7" touchscreen tablet, featuring a modern, user-friendly interface that puts professional-grade control at your fingertips. This high-resolution display provides crystal-clear visuals and responsive touch controls, making it effortless to navigate through massage programs, adjust intensity levels, customize techniques, and fine-tune every aspect of your therapeutic session.
Your massage chair has a built-in health scanning sensor that monitors your blood oxygen, microcirculation, heart rate, and fatigue value. Once you are given a fatigue value, the massage chair will recommend programs for you to try to get your numbers back into normal ranges. All of this is conveniently displayed on the 7" touch screen tablet, creating an intelligent wellness experience that goes beyond simple massage—helping you understand and address your body's needs through data-driven recommendations.


The Sensation 4D DualFlex features comprehensive airbag compression therapy that gently squeezes and releases key areas of the body, improving circulation, relieving tension, and enhancing the benefits of your massage from shoulders to feet. These intelligent airbags work in harmony with the 4D Dual Mechanism to provide a complete therapeutic experience that addresses both surface-level tension through compression and deeper muscle relief through roller massage.
The airbag system can be controlled and fine-tuned through the Custom Massage Generator, allowing you to customize the intensity and focus of your compression therapy based on your specific needs and preferences. Whether you prefer gentle compression for relaxation or more intense pressure for deep tissue stimulation and improved circulation, the system adapts seamlessly to create the perfect balance of air massage and roller therapy. This combination approach ensures that every part of your body receives comprehensive therapeutic attention.


Heating modules located in the lower back of the chair and legs provide a soothing sensation and loosen your muscles to better prepare your body for the massage. The Sensation 4D DualFlex's dual heat therapy creates a therapeutic environment that prepares your muscles for optimal massage effectiveness, melting away tension, reducing stiffness, and enhancing circulation in key tension-prone areas.
Heat therapy has been scientifically proven to improve muscle flexibility, accelerate recovery, reduce pain perception, and enhance the effectiveness of massage techniques by increasing blood flow and preparing muscles for deeper manipulation. By combining targeted lumbar and leg heating with the powerful 4D Dual Mechanism, the Sensation 4D DualFlex creates a synergistic therapeutic effect that provides relief beyond what either feature could achieve independently. The gentle warmth soothes sore muscles and relaxes connective tissue, while the dual rollers work to release deep-seated tension and knots.


Select from 20 expertly crafted auto programs, spanning soothing relaxation to energizing full-body stretches, and save your favorite sessions to MyMemory® for effortless recall anytime. The Sensation 4D DualFlex puts an extensive library of professional massage routines at your fingertips, while the 8 slots of MyMemory® let you build and save completely customized massage sequences for instant access whenever you want to enjoy them again.
The MyMemory® system puts you in complete control, allowing you to experiment with different combinations of techniques, intensities, and settings until you discover the perfect massage configuration for your specific needs. Whether you prefer a gentle, relaxing sequence for stress relief, an invigorating routine for post-workout recovery, or a targeted deep tissue session for chronic tension areas, MyMemory® lets you create, save, and instantly recall your ideal therapeutic experience. It's like having a personal massage therapist who knows exactly what works best for your body.


Enjoy enhanced control at your fingertips with the quick-access control panel, allowing you to adjust 4D intensity via the smart dial, backrest and footrest incline or recline, heat, zero gravity, and pause your massage session. The panel also features a wireless charging pad for smart devices, with a conveniently placed USB-C charging port on the opposite side—ensuring you stay connected and powered throughout your massage without interrupting your relaxation experience.
The wireless charging pad supports Qi-compatible devices, making it compatible with most modern smartphones and eliminating the need for cables or searching for outlets. Simply place your device on the integrated charging surface and enjoy uninterrupted power while you relax. The additional USB-C port provides a wired charging option for devices that may not support wireless charging or for times when you prefer a direct connection. Together with Intelligent Voice Command, you have multiple ways to control your massage—hands-free voice activation, quick-access panel, or the full 7" tablet interface.


Set the mood and enhance your relaxation with 12 soothing Chromotherapy color options that softly illuminate along the sides of your massage chair, creating a calming, spa-like ambiance from the upper arm panels. Chromotherapy—the use of color for therapeutic benefit—has been used for centuries to promote balance, relaxation, and wellness, and the Sensation 4D DualFlex brings this ancient practice into your modern massage experience.
Whether you prefer calming blues for relaxation, energizing greens for balance, or warm amber tones for comfort, the 12 selectable color options allow you to create the perfect atmosphere for your massage session. The soft illumination from the upper arm panels creates an immersive environment that enhances both physical and mental relaxation, transforming your massage into a complete multisensory wellness experience. Combined with SootheMe® Sound Therapy and your choice of music or nature sounds, chromotherapy completes the spa-like ambiance right in your home.


Initially developed by NASA, Zero gravity positioning elevates your feet above your heart, relieves pressure on your spine, and improves circulation. This allows the spine to decompress and provides a sense of weightlessness to aid in the therapeutic benefits of the massage chair. The Sensation 4D DualFlex's weightless zero gravity recline works in harmony with the Near-Flat Reclining Decompression Stretch to create the ideal positioning for maximum therapeutic benefit.
When combined with the Flex Track's stretching capability and the 4D Dual Mechanism's comprehensive coverage, zero gravity positioning creates a multi-layered therapeutic experience that addresses physical tension, promotes circulation, and induces deep relaxation. This optimal positioning means your body receives massage in the most effective configuration possible—with reduced spinal pressure, improved blood flow, and muscles in an ideal state for therapeutic manipulation. It's the foundation that makes every other feature of the Sensation 4D DualFlex more effective.


Transform your massage session into a complete multisensory wellness experience with the Sensation 4D DualFlex's integrated Premium Bluetooth speakers and SootheMe® Sound Therapy. Immersive speakers located in the headrest connect to a phone or other Bluetooth device, allowing you to stream music, guided meditations, ambient soundscapes, and any other form of audio to enhance the mental experience of your massage.
No need to find something to stream—SootheMe® provides on-board nature sounds to choose from. The sound menu is right on the tablet to envelop yourself in soundscapes that are designed to help you relax. Whether you choose your own music for motivation and energy, guided meditation for mindfulness, or SootheMe® nature sounds for deep tranquility, the audio system creates the perfect atmosphere for complete wellness and rejuvenation. Combined with chromotherapy lighting and the 4D Dual Mechanism, you have a complete spa experience in the comfort of your home.
