Infinity Circadian 4D DualFlex Massage Chair
Description
Named the International Business Times Editor's Pick for Best Massage Chair of 2026, the Infinity Circadian 4D DualFlex is the most advanced massage chair Infinity has ever produced. At the core of its technology is the Syner-D Dual Back Mechanism - two synchronized 4D robotic massage mechanisms that move in choreographed rhythm from your neck all the way to your glutes, mimicking the hands of two skilled masseuses. The 49" Flex-Track blends the full-body coverage of an L-Track with the spinal benefits of an S-Track, delivering superior decompression and a comprehensive neck-to-glutes massage unlike anything available at this level.
What truly sets the Circadian apart is its AI-driven personalization: simply place your thumb on the Smart Massage button to scan your heart rate, blood oxygen, and fatigue levels, and the chair will recommend a custom massage program tailored to your body's exact needs in that moment. Pair that with high-fidelity Harman Kardon premium audio, an 8" touch screen tablet, zero-wall-fit space-saving technology, and wireless charging, and you have a complete wellness system designed to make you feel better and live better - every single day.

FAQ
What is the difference between the Flex-Track and a standard L-Track or S-Track?
The Flex-Track is a hybrid design exclusive to the Circadian DualFlex. A standard L-Track extends massage coverage from the neck down through the glutes, while an S-Track follows the natural curve of the spine for deeper pressure. The Flex-Track combines both - it follows the spinal curve (S-Track) while also extending down to the glutes (L-Track), and the track physically opens upon recline to enhance spinal decompression. The result is more comprehensive coverage and a deeper, more therapeutic stretch than either track type alone.
How does the AI health sensor and personalized massage work?
Simply place your thumb on the Smart Massage button on the quick-access control panel. The built-in health sensor reads your blood oxygen level, heart rate, and fatigue level in seconds. Based on those readings, the chair's AI system analyzes your current condition and automatically recommends a massage program designed to address your specific needs in that moment - whether that's deep muscle relief, gentle relaxation, or an energizing session. It's a fully hands-free, personalized experience every time.
How much wall space does the Circadian DualFlex require?
Thanks to Zero Wall Fit technology, the chair only needs a few inches of clearance from the wall. As the chair reclines, it slides forward rather than backward, so you don't need the large open space behind the chair that traditional recliners require. This makes it practical for most living rooms, bedrooms, and home offices without major furniture rearrangement.
Is the Circadian DualFlex suitable for taller or heavier users?
Yes. The chair is designed for users between 5'2" and 6'6" tall and supports a maximum user weight of 300 lbs. TrueFit Body Scanning technology automatically adjusts the massage to your body's specific proportions, so users at different ends of the height range still get a precisely fitted experience.
What does the warranty cover, and how do I make a claim?
The Infinity Care 5-Year Residential Limited Warranty includes: 1 year of Complete Care (no-cost parts and in-home labor if necessary), 3 years of no-cost parts replacement, and 5 years of structural framework coverage. Extended plans are also available - Infinity Care Plus covers 3 years of labor, parts, and frame for $399, and Infinity Care Max covers 5 full years of labor, parts, and frame for $599. To initiate a warranty claim, contact Infinity's USA-based support team at 603-910-5000. All service is performed by Infinity-authorized technicians.
Does this chair require professional assembly?
The Circadian DualFlex requires some assembly upon delivery. An assembly guide, quick start guide, and assembly video are provided to walk you through the process. For customers who prefer professional setup, in-home service is available through Infinity's authorized service network under the Complete Care warranty period. We recommend reviewing the assembly guide before your delivery date so you're prepared.
