Infinity IT-8500 Plus Massage Chair
Quick take
The Infinity IT-8500 Plus offers S-Track coverage via a 2D roller. For buyers matching the specification profile, it is worth a close look as part of your research.
S-track: neck and upper back focus
The Infinity IT-8500 Plus uses an S-track roller, which follows the natural S-curve of the spine from the neck through the upper and mid back. It is best for buyers whose primary concern is upper-body tension: neck stiffness, shoulder tightness, and mid-back ache from desk work. If your lower back pain extends into the hips or glutes, a chair with an L-track or SL-track will serve you better.
2D roller: gentle and consistent
The 2D roller follows a fixed depth path along the track, delivering a lighter and more predictable massage experience. If you prefer gentleness over intensity, or if you are new to massage chairs and want to ease in before deciding what kind of pressure works for you, a 2D roller is less likely to feel too intense. It is also worth noting that most returns in this category happen because the massage was too rough: a 2D roller eliminates that risk.

Common questions
Can the Infinity IT-8500 Plus help with lower back pain?
The S-track roller reaches the upper and mid back but does not extend into the lower lumbar, sacral area, or hips. If your lower back pain is in the thoracic or upper lumbar region, an S-track chair can provide some relief. For pain in the lower lumbar, sacrum, or hips, you will need an L-track or SL-track chair.
What does zero gravity do in a massage chair?
Zero gravity recline positions your body so your knees are slightly above your heart, which reduces the load on your spine and allows the massage rollers to make deeper contact along the back. Most buyers find the massage feels more effective in zero gravity than in the upright position.
Is the Infinity IT-8500 Plus covered by a warranty?
Warranty terms vary by retailer and purchase date. For the most current warranty information, check the product page at the retailer linked above. In general, reputable massage chair brands offer 1-10 year warranties depending on brand and tier, covering structural components separately from soft goods.
