Top Features of the Osaki AI Xrest 4D

Precision Shoulder Relief

The Osaki AI Xrest 4D offers a carefully designed shoulder massage system that uses 20 airbags to deliver focused compression therapy.

These airbags are strategically positioned to contour the shoulders and neck for balanced pressure.

By inflating and deflating in smooth motions, they gently loosen tight muscles and encourage relaxation. This feature provides an immersive experience that feels tailored to the upper body.

With its thoughtful design, the shoulder massage function complements the chair’s other programs, ensuring users enjoy targeted attention where it is most needed.

It is ideal for those who want a refined and thorough shoulder massage session.

Advanced 4D Massage Experience

The Osaki AI Xrest 4D takes massage performance to the next level with its versatile 4D mechanism.

Users can choose from five different speeds, seven intensity levels, and multiple width settings for a deeply personalized massage.

This flexibility allows the rollers to mimic the natural motions of human hands with impressive accuracy.

The chair also offers spot treatments and partial massage options, letting you target specific areas that need extra care.

Whether you prefer a lighter session or a stronger, more invigorating massage, the 4D technology makes it possible. It creates a versatile and immersive experience suited to a variety of preferences.
