Common questions about the Infinity IT-9800
- What kind of roller coverage does the Infinity IT-9800 offer?
- The Infinity IT-9800 uses an S-Track — the rollers follow your spine's natural curve from the cervical region down to the lower lumbar. Precise, focused, and well-suited for targeted spinal decompression.
- What type of rollers does the Infinity IT-9800 have?
- The Infinity IT-9800 is built with 2D rollers, which follow a fixed-depth path up and down the spine. Simple, dependable, and particularly good for regular daily use or lighter therapeutic sessions.
- Does the Infinity IT-9800 support zero gravity reclining?
- Yes, the Infinity IT-9800 supports zero gravity recline — a position that distributes body weight evenly and reduces spinal load. It also allows the rollers to reach deeper into muscle tissue, making the same pressure setting feel more effective.
- Does the Infinity IT-9800 include heat therapy?
- Heat therapy is built into the Infinity IT-9800. It pre-warms muscle tissue to improve roller penetration — a small feature that makes a measurable difference, particularly for chronic tension in the lumbar region.
- What is the maximum weight capacity of the Infinity IT-9800?
- The Infinity IT-9800 supports up to 350 lbs (159 kg). This is a hard limit from the manufacturer — the motor and frame are rated to this specification.
- How long is the warranty on the Infinity IT-9800?
- The Infinity IT-9800 includes a 5 years warranty. Always confirm exact coverage terms — particularly in-home service provisions — with your retailer at time of purchase.
- Where is the Infinity IT-9800 available for purchase?
- The Infinity IT-9800 is currently available through Direct. Use the links on this page for current pricing and availability.
