Two Massage Mechanisms Working in Choreographed Rhythm

The Circadian DualFlex Syner-D® system runs tandem back mechanisms that mimic the human hands of two masseuses, moving in coordinated rhythm from your neck all the way down to your glutes. One set of rollers never has to do the work of two, so coverage stays continuous instead of jumping from zone to zone.

Ride along the 49" Flex-Track, which blends the full-body reach of an L-Track with the deep stretch of an S-Track. The track opens up on recline while the mechanism continues down to the gluteus region, delivering a deep full-back stretch and a true neck-to-glutes massage.

Massage techniques on tap:

• Kneading
• Tapping
• Knocking
• Shiatsu
• Sync
• 4D Shiatsu

Vitals Scanning and AI Personalization in the Infinity Circadian DualFlex 4D Massage Chair

Rest your thumb on the Smart Massage button, set into a silver panel on the armrest, and the built-in health sensor goes to work. In moments you get a personalized wellness snapshot covering heart rate, blood oxygen levels, and overall fatigue.

From there the chair does the thinking. It evaluates your condition and recommends a custom-tailored massage program aimed at the muscles that need attention, so you are never guessing which of the settings will actually help.

Pair that with TrueFit® Body Scanning, where hardware and software pinpoint your size and shape before the rollers move. The result is a massage mapped to your body, not a generic pattern.

Full Body Coverage From Your Arms Down to Your Soles

Your back is only part of the story. The lower half of the chair is where a lot of chairs cut corners, and this one does not.

• Complete Calf™ Kneading + Oscillation: calf rollers combine with oscillating movement and compression air cells to simulate hands gently easing tension in the lower legs.
• Total Sole Reflexology Foot Rollers: triple rollers per foot cover the full sole of each foot, for a thorough, soothing foot massage.
• Shiatsu Arm Rollers: soothing arm kneading paired with gentle compression therapy to refresh tired muscles.

Air Compression Therapy Wrapped Around You

Airbags sit throughout the chair, inflating and deflating to press and release the muscles in a squeezing motion rollers alone cannot reproduce. Shoulders, arms, calves, feet: the compression sensation reaches the soft tissue around the areas the mechanisms are already working, so a session feels like a full-body treatment rather than a back rub.

Soothing Lumbar and Foot Heat in the Infinity Circadian DualFlex Chair

Heating modules in the lower back and the footrest warm you before and during the massage. Warm muscles loosen up, which means the rollers can work deeper with less resistance and you get more out of every program.

Cold feet after a long day? The footrest heat handles that too, and it pairs naturally with the calf and sole work happening at the same time.

Premium Harman/Kardon® Audio and Nature Sound Therapy

High fidelity Harman/Kardon® speakers are built into the headrest behind a copper-trimmed grille carrying the harman/kardon badge, and connect to your phone or other Bluetooth device. Stream music, guided meditations, ambient soundscapes, or anything else that sets the mood for your session.

Prefer something ready to go? SootheMe™ Nature Sounds puts a sound menu right on the remote, so you can wrap yourself in soundscapes designed to help you relax without reaching for another device.

Hands Free Voice Control and the 8" Touch Screen Tablet

Three ways to run your massage, and none of them ask you to interrupt it.

• Intelligent Voice Command + Control: start your massage programs hands free.
• 8" Touch Screen Tablet: side-mounted on an adjustable arm, with full control of every aspect of the massage from a lit menu with Auto, Infinity Control, MyMemory, Adjustments, Sound and System.
• Quick Access Control Panel: armrest controls at your fingertips, with a round power button, six illuminated hexagonal function keys, and the health sensor at the left end, all set above diamond-quilted leather, so there is no reaching for a remote mid-session.
• MyMassage® Memory Programs: save the settings you love and call them back instantly.

Charge Your Phone While You Recharge Your Body

A wireless charging pad is recessed right into the quilted armrest, with a USB-C charging port alongside it. Drop your phone down, let it top up while you stream your playlist through the headrest speakers, and walk away from your session with a full battery.

Zero Wall Fit™ Space-Saving Design in the Infinity Massage Chairs Circadian DualFlex Massage Chair

Big chairs usually demand a big gap behind them. Zero Wall Fit™ slides the chair forward as it reclines, so it claims far less floor space in your room and can live much closer to the wall, with as little as 2" of clearance behind it.

That matters when your living room, bedroom, or office does not have a spare corner to sacrifice. Upright, the chair measures 58" high, 32" wide, and 49" deep; reclined it drops to 33.00" high and extends to 75.00".

What the Nature Sound Menu Feels Like

Crackling fire. An open meadow. Rain on an umbrella. Waves breaking on the shore. The SootheMe™ menu gives your mind somewhere to go while the mechanisms handle your body, and the Harman/Kardon® headrest speakers make those soundscapes feel close rather than piped in.

Body Scanning That Maps You Before It Touches You

TrueFit® Body Scanning measures from headrest to footrest, locating your shoulders, spine, and legs so the rollers land where they should. With an optimal user height range of 5' 2" to 6' 6", the same chair adapts to very different bodies in the same household without anyone fiddling with manual settings.
