Infinity Dynasty 4D Massage Chair
The Infinity Dynasty 4D is a premium full-body massage chair built around an advanced 4D back and glute massage mechanism and a long 49-inch L-Track.
It combines 4D massage with Complete Calf kneading and oscillation, triple foot rollers, TrueFit body scanning, Zero Gravity, Zero Wall Fit, lumbar heat, air compression, voice control, app control, Bluetooth audio, wireless charging, and 12 automatic programs.
What Makes the Infinity Dynasty 4D Different?
The Dynasty combines advanced 4D massage with extended L-Track coverage, allowing the mechanism to travel from the neck and shoulders down through the glute region.
It also places more emphasis on lower-body massage than many premium chairs by combining active calf kneading, oscillation, compression, and triple foot rollers.
That makes the Dynasty particularly appealing to shoppers who want an advanced full-body 4D massage chair rather than a stretch-focused S-Track model.
Why Choose the Infinity Dynasty 4D?
True 4D Massage
The massage mechanism varies position, depth, and movement speed to create a more dynamic massage experience.
49-Inch L-Track
The long track extends massage coverage from the neck and shoulders through the back and glute region.
Advanced Lower-Body Massage
Calf kneading, oscillation, compression, and triple foot rollers provide extensive lower-leg and foot coverage.
4D Back & Glute Massage Mechanism
The Dynasty uses Infinity's 4D massage technology to vary massage position, depth, and movement speed.
The mechanism moves:
- Up and down
- Left and right
- In and out to vary massage depth
- At variable speeds to change massage rhythm
This gives the Dynasty a more adjustable massage feel than conventional fixed-depth mechanisms.
49-Inch L-Track Massage Coverage
The Dynasty's 49-inch L-Track extends the massage mechanism from the neck and shoulders down the back and into the glute area.
This extended track is an important distinction for shoppers who prioritize broad full-body roller coverage.
TrueFit Body Scanning & Footrest Extension
TrueFit technology scans the user's body size and shape to help align the massage mechanism with the individual.
TrueFit footrest extension also adjusts the lower portion of the chair to better accommodate users within the recommended height range.
Complete Calf Kneading & Oscillation
The Dynasty goes beyond air-only calf compression.
Dedicated calf rollers combine with oscillating movement and compression air cells to create a more active lower-leg massage.
This is one of the strongest reasons to consider the Dynasty if lower-body massage is a priority.
Triple Foot Roller Total Sole Reflexology
Each footwell includes three shiatsu rollers positioned beneath the sole.
The triple-roller design provides broad coverage across the bottom of each foot during full-body massage sessions.
Zero Gravity & Zero Wall Fit
Weightless Zero Gravity
Zero Gravity recline positions the body in a supported posture during massage and relaxation.
Only About 2 Inches Behind the Chair
Zero Wall Fit technology moves the chair forward as it reclines, requiring only about 2 inches of rear clearance.
Lumbar Heat & Air Compression
Integrated lumbar heat provides gentle warmth around the lower-back area.
Air cells throughout the chair inflate and deflate to provide compression around multiple body zones.
12 Automatic Massage Programs
The Infinity Dynasty includes 12 built-in automatic massage programs plus manual controls.
Available massage techniques include:
- Kneading
- Tapping
- Knocking
- Shiatsu
- Synch
- 4D Shiatsu
Voice Control, Mobile App & Smart Dial
Intelligent Voice Control
Compatible massage programs can be activated using hands-free voice commands.
iOS & Android App
Operate compatible chair functions from an Apple or Android device.
Smart Dial Controller
A convenient physical dial gives quick access to commonly used chair functions.
Bluetooth Audio, SootheMe & Chromotherapy
Bluetooth Speakers
Stream music, podcasts, or relaxing audio through the chair's built-in speakers.
SootheMe Sound Therapy
Built-in soundscapes provide an additional audio option without requiring your own content.
Chromotherapy Lighting
