The rollers move in multiple directions to mimic realistic hand motions that feel steady and dynamic. You can also choose spot or partial massages to focus on areas needing extra attention.
These options allow the chair to adapt to a wide range of comfort levels. Whether you prefer a gentle touch or a deeper sensation, the system provides reliable flexibility for a well-rounded experience.
Convenient Voice-Activated Operation
The Platinum AI Xrest makes control effortless with built-in smart voice technology. Its Alexa compatibility lets you adjust settings, start programs, or modify features using preset voice commands from the manual.

Combining modern voice control with traditional massage features creates a seamless experience that supports relaxation without interruptions. It’s a practical and efficient way to enjoy your preferred massage setup.
Zero Gravity Recline with Space-Saving Design
The Xrest includes a zero gravity reclining option inspired by NASA concepts to create a light, weightless feel. This position lifts your legs above your heart, helping your body settle comfortably into the chair.

The balanced angle enhances the massage rollers’ contact and supports a more even distribution of weight.
Alongside this, the space-saving track allows the chair to recline fully while placed only about three inches from the wall.
This efficient design makes it easier to fit the Xrest into smaller rooms without sacrificing performance. The combined features offer a comfortable, adaptable setup for various spaces.
Gentle Lumbar and Foot Heating Function
