The Infinity IT-8500 X3 is the third generation of Infinity's most popular chair — a switchable 3D/4D L-track with TrueFit™ body scanning, dual heat, triple foot rollers, and a stretch program refined over multiple iterations. The X3 update brings improved roller mechanics and a more responsive 4D system over the previous generation. If you've been comparing the IT-8500 Plus and the X3 and wondering which to choose, the X3 is the stronger performer for buyers who use the chair daily.

3D vs. 4D — What's the Difference?

3D rollers adjust depth and speed. 4D adds a fourth dimension: variable speed rhythm that mimics the natural cadence of a human hand — speeding up and slowing down mid-stroke rather than maintaining a fixed pace. The X3 lets you switch between both modes, so you can use 3D for lighter recovery sessions and 4D when you want the deeper, more responsive feel.

Frequently Asked Questions

How does the IT-8500 X3 differ from the IT-8500 Plus?
The X3 is the newer generation with improved 4D roller mechanics, a more responsive body scanning system, and triple foot rollers vs. the Plus's dual rollers. For daily users who want the most current Infinity platform, the X3 is the stronger choice. The Plus remains a solid option at a lower price point.

What does TrueFit™ body scanning do?
Before each session, the chair scans your back to map your shoulder position, height, and spinal curvature. The roller system then calibrates its path to your specific anatomy — so the massage starts at the correct position on your neck and follows your spine accurately rather than running a fixed program designed for an average user.

Is White Glove delivery available?
White Glove delivery is available in select locations at additional cost — it is not included in the standard price. Contact us before ordering to confirm availability and pricing in your area. Free standard shipping to the lower 48 is always included.

What financing options are available?
