Circadian 4D DualFlex fits buyers who prefer its wider documented fit range, dual mechanisms and current control package and accept that its sensor does not produce medical measurements.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
Circadian 4D DualFlex was checked against its manufacturer record, the current category collection and the nearest ownership alternatives.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner discussion repeatedly returns to thumb-sensor repeatability, dual-mechanism feel, 62-to-78-inch fit, calf pressure, tablet recovery, delivery and in-home service rather than specifications alone.
These are self-reported experiences from a changing mix of owners, conditions and software versions. They identify questions to test, not a failure rate. Comfort, anatomy, mobility, medical history, pressure tolerance, firmware, delivery route and service region vary materially.Current self-selected discussions raise dual-mechanism, sensor, fit, delivery and service questions. They do not validate wellness sensors, medical claims or failure rates.
Test the chair without relying on the sensor recommendation and compare fit at the height-range edges; owner reports cannot validate the sensor or establish health outcomes.

The independent dealer lists one Circadian 4D DualFlex at $16,999 and separates delivery, warranty upgrades and purchasing terms from the chair price.
Infinity Massage Chairs publishes setup, compatibility or service material that makes this purchase boundary explicit: The $16,999 listing is one chair before upgraded labor or delivery. The thumb sensor's heart-rate, oxygen and fatigue outputs are wellness prompts only and cannot diagnose or prescribe. This is a powered comfort product, not a diagnosis or treatment recommendation. FDA establishment registration or device listing is not FDA approval, clearance or proof that a chair cures, treats or prevents disease. Massage-chair classification under 21 CFR 890.5660 does not support circulation, inflammation, spinal-decompression or pain-treatment promises. Body scans, heart-rate, oxygen, stress, fatigue or pressure sensors are non-diagnostic and must not guide medical care. Read the exact manual and ask a clinician before use when it directs consultation, including for an implanted device, pregnancy, recent injury or surgery, impaired sensation, bone or vascular conditions or another relevant health concern. Stop for pain, numbness, dizziness or distress. Keep children and pets away from the chair, footrest, doors and recline path; protect pinch points, use a grounded undamaged outlet, unplug before cleaning or service and enter or exit only when the mechanism is stopped. Verify only the certification mark and model actually documented by an OSHA-recognized NRTL. Roller labels such as 2D, 3D and 4D are not standardized comfort rankings, so every intended user needs a real fit and minimum-intensity trial. App, voice, profile and sensor data require a privacy, permission, update and local-control review. Delivery route, doorway, turns, floor loading, assembly, return freight, warranty labor, parts and post-warranty service are part of the purchase.
The federal classification describes powered massage devices as Class I physical-medicine devices. Classification does not turn a home chair into evidence that it diagnoses, cures or treats a condition.
Current hands-on comparison distinguishes roller architecture, track, fit, lower-body behavior, controls, warranty and price while keeping showroom comfort subjective and tied to the tested user.
FDA explains establishment registration and device listing requirements. Registration or listing does not mean FDA has approved, cleared or endorsed the establishment or device.
Current self-selected discussions raise dual-mechanism, sensor, fit, delivery and service questions. They do not validate wellness sensors, medical claims or failure rates.

The manufacturer record, current market collection, support material and independent category evidence were checked on August 17, 2026. The checkout package and regional support path still need verification. Owner reports are retained as bounded experience, not a reliability rate.

Comfort, pressure and body contact are subjective and user-specific. Marketing language about relief, recovery, therapy, circulation, inflammation, decompression, pain, posture or wellness is not retained as a medical claim. FDA registration is not approval. Only the exact certification mark, model and current NRTL directory record may be stated. Body and wellness sensors are non-diagnostic. Current software is separated from announced or promised features, especially on Super Novo 3.0.
