Common questions about the Infinity Circadian DualFlex 4D
- What track type does the Infinity Circadian DualFlex 4D use?
- S-Track on the Infinity Circadian DualFlex 4D means the roller path mirrors the natural S-curve of your spine, neck to lower back. Compact and precise — effective for people who want focused spinal work rather than full lower-body coverage.
- What roller technology does the Infinity Circadian DualFlex 4D use?
- The Infinity Circadian DualFlex 4D features 4D rollers, which control both depth and the speed of each individual stroke independently. The result is a more rhythmic, human-like massage — the rollers can slow down and press deeper on tight spots, then speed up through less tense areas.
- Can the Infinity Circadian DualFlex 4D recline into a zero gravity position?
- Yes — the Infinity Circadian DualFlex 4D reclines into a zero gravity position, tilting your body so your legs rise above your heart. This reduces spinal compression and allows the rollers to work with gravity rather than against it, deepening the therapeutic effect.
- Is there built-in heat on the Infinity Circadian DualFlex 4D?
- Yes — the Infinity Circadian DualFlex 4D includes built-in heat, typically in the lumbar and sometimes calf sections. Heat loosens muscle tissue before and during the massage, making roller pressure more effective without needing to increase intensity.
- How much weight can the Infinity Circadian DualFlex 4D support?
- The Infinity Circadian DualFlex 4D is rated for a maximum user weight of 300 lbs (136 kg). Staying within this limit ensures both effective massage delivery and long-term mechanical reliability.
- Who does the Infinity Circadian DualFlex 4D fit in terms of height?
- The Infinity Circadian DualFlex 4D is calibrated for users between 5′4″ and 6′0″. Body scanning will auto-adjust the roller path, but the physical dimensions of the chair are optimised for this range.
- How many airbags does the Infinity Circadian DualFlex 4D have?
- The Infinity Circadian DualFlex 4D is fitted with 88 airbags distributed across the shoulders, arms, hips, and calves. More airbags generally means better coverage and more even compression pressure.
- Is the Infinity Circadian DualFlex 4D covered by a warranty?
- 5 years warranty on the Infinity Circadian DualFlex 4D. Coverage terms (parts vs. labour, in-home vs. depot service) can vary by retailer and region, so verify before buying.
- Which retailers carry the Infinity Circadian DualFlex 4D?
- You can find the Infinity Circadian DualFlex 4D at Direct. Prices and stock levels vary by retailer — our links point to current listings.
- What type of buyer is the Infinity Circadian DualFlex 4D designed for?
- Buyers who want the most technologically complete chair Infinity makes with the highest airbag count and the brand's advanced Flex-Track system
