Two synchronized back mechanisms, a 49-inch Flex-Track, and unusually active calf, foot, and arm systems — built for buyers who care as much about stretch character and fit as feature count.
01 · Quick Model Decision
A dual-mechanism chair with a stretch-first personality.
In brief
The Infinity Ultra Imperial Syner-D pairs two synchronized back mechanisms with a 49-inch Flex-Track, TrueFit scanning, 54 air cells, active calf and foot systems, lumbar and foot heat, and an 8-inch tablet. Its tradeoff is scale: at 352.74 pounds and 77.20 inches at full recline, it needs deliberate body-fit and room planning.
Two back mechanisms
Syner-D coordinates two back mechanisms across upper and lower regions.
49-inch Flex-Track
The track maintains long coverage while opening during recline for a stretch-oriented feel.
Active lower body
Calf kneading, triple foot rollers, compression, and foot heat give the leg section an active role.
Measured personalization
TrueFit maps user size and shape; the Health Sensor uses wellness readings to suggest a program, not diagnose.
Repeatable control
Twelve presets, Infinity Control, MyMemory, and adjustable intensity support both quick and hands-on sessions.
Premium interface
An 8-inch tablet, quick controls, voice, Harman/Kardon audio, and charging handle daily operation.

Fig. 01 — Syner-D Dual Back Mechanisms
The Architecture
Two mechanisms divide the work.
Syner-D uses two tandem back mechanisms in a coordinated rhythm from neck toward glutes, combining 2D, 3D, and 4D operation. The point is simultaneous regional work rather than a single assembly traveling alone.
- Back mechanismsTwo synchronized units
- TechniquesKnead · tap · knock · Shiatsu · sync · 4D Shiatsu
Decision pointJudge how naturally the two mechanisms hand off between regions.
The Personalization
Scan first. Then fine-tune.
TrueFit maps user size and shape for massage positioning. The Health Sensor reads heart rate, blood oxygen, and fatigue index to suggest a program; treat these as wellness inputs, not clinical measurements.
- Body scanTrueFit hardware + software
- Health sensorWellness readings + program suggestion
Decision pointAfter scanning, still check shoulder position, intensity, and focus.
The Surround
Compression and warmth around the rollers.
Fifty-four air cells add regional compression while separate modules warm the lower back and feet. Air offers five active levels; each heat zone offers three active levels plus off.
- Air system54 cells · regional control
- HeatLower back + feet
Decision pointTest pressure by region; firmer is not automatically better.
The Extremities
The lower body is not an afterthought.
Complete Calf Kneading + Oscillation combines rollers, movement, and compression. Total Sole Reflexology uses three rollers per foot, while Shiatsu arm rollers add mechanical kneading. Each system can be adjusted or switched off.
- CalvesRollers + oscillation + compression
- FeetTriple rollers per foot
- ArmsShiatsu arm rollers
Decision pointCalf pressure and foot length deserve as much testing as the back mechanism.
The Recline
Recline deeply without giving the wall the room.
The manual provides two zero-gravity positions. Zero Wall Fit slides the chair forward during recline, with 2 inches required behind and 24 inches in front for footrest travel.
- Zero gravityTwo positions
- Rear clearance2 inches
- Front clearance24 inches
Decision pointPlan for the full 77.20-inch reclined length, not only the rear gap.
The Interface
A complex chair should not feel complicated.
The 8-inch tablet organizes programs, Infinity Control, MyMemory, adjustments, audio, and settings. Quick-access controls and voice handle common changes; Harman/Kardon audio, SootheMe sounds, wireless charging, and USB-C add convenience.
- Main controller8-inch touch tablet
- Hands-freeIntelligent voice control
- AudioHarman/Kardon + SootheMe sounds
Decision pointTest intensity, focus, calf speed, heat, and recline while seated.
03 · The Stretch
The track changes character when the chair opens.
The Ultra Imperial is a stretch-oriented dual-mechanism chair. Its 49-inch Flex-Track opens during recline while Syner-D lets upper and lower mechanisms keep separate jobs.
The manual lists 12 presets, including Extension, Post Workout, Waist & Glutes, Rest & Sleep, Neck & Shoulder, and Back & Spine. Time, air, rollers, heat, recline, and leg extension remain adjustable.
- i.12 preset auto programsOne-tap starting points
- ii.MyMemory programsSave preferred manual sequences
- iii.Infinity ControlWhole · Partial · Point focus
- iv.Maximum 4D levelFive levels or off
- v.Session timing10 · 20 · 30 minutes
The Ultra Imperial is designed for relaxation, comfort, and a home wellness or recovery routine. Its Health Sensor and massage systems are not diagnostic tools and do not replace professional medical care.
04 · Fit & Personalization
The published range is only the first fit check.
Published fit is 62 to 78 inches tall and up to 300 pounds, with an 18-inch seat depth, 19-inch hip width, and 22-inch shoulder width. These narrow the shortlist, but calf, foot, shoulder, and roller fit still need a real comfort check.
Compare this model in person →Let TrueFit establish the starting map.
The scan maps size and shape; verify shoulder placement after it runs.
Published fit: 5'2″ to 6'6″, up to 300 pounds.
Near either end of the range, check shoulder alignment, leg extension, and foot placement.
18-inch seat depth. 19-inch hip width. 22-inch shoulder width.
Use the numbers for screening, then judge arm and shoulder comfort in the chair.
Fine-tune the systems instead of enduring them.
Air offers five active levels; arm, foot, and calf systems offer three speeds plus off.
Confirm the movement envelope.
Match leg extension, test both zero-gravity positions, and verify the 77.20-inch reclined length in your room.

08 · Buyer Fit
Who should keep the Ultra Imperial on the shortlist?
A strong fit if you…
- Want two synchronized back mechanisms rather than one.
- Value a 49-inch Flex-Track and stretch-oriented recline.
- Want active calf, foot, and arm systems.
- Share the chair and want scanning, memory, and adjustable pressure.
- Fit within the published height and weight guidance.
- Can accommodate its 352.74-pound weight and 77.20-inch reclined length.
Consider another model if you…
- Want a smaller or lighter chair.
- Prefer fewer systems and simpler control.
- Fall outside the fit range or find the seat, shoulders, calves, or feet restrictive.
- Cannot provide the documented rear and front clearances.
- Want a close alternative with different seat geometry and footprint.
Closest Alternative
The Circadian is close enough that fit becomes the tiebreaker.
The Infinity Circadian DualFlex 4D shares the dual-back architecture, 49-inch Flex-Track, scanning, active lower body, heat, tablet, voice, memory, and Harman/Kardon audio. Fit, footprint, finishes, and documentation become the useful separators.
