Top Features of the Kyota Yutaka M898

Advanced 4D Back Massage Mechanism

The Kyota Yutaka M898 features an advanced 4D massage mechanism designed to mimic the deep, therapeutic pressure of human hands.

It moves in four directions: up and down, side to side, in and out for intensity adjustment, and includes variable speed control for a more realistic massage experience. 

This added dimension of speed variation makes the massage feel more natural and responsive to your body’s needs.

Covering the back and gluteus areas, this technology helps deliver a customized, spa-like experience in the comfort of your home, with an emphasis on replicating the sensation of a real deep tissue massage.

Triple Roller Reflexology for Full Foot Coverage

This massage chair offers triple shiatsu foot rollers in each footrest, giving your soles complete reflexology coverage. These rollers target key acupressure points associated with different organs and systems throughout the body.

The three-roller design ensures maximum surface contact from heel to toe, delivering a more thorough and invigorating massage experience. The foot massage helps relax tired feet, improve circulation, and provide relief from daily strain.

It’s one of the most advanced foot reflexology systems in any massage chair today, offering a therapeutic treatment that goes beyond simple vibration or basic kneading found in standard massage footrests.

49" L-Track Design

The Kyota Yutaka M898 uses a 49-inch L-Track design that seamlessly follows the natural curve of your spine.

Starting from the neck and extending down through the lower back and gluteus muscles, the track allows the massage rollers to reach more areas than traditional S-track chairs.

 This extended coverage delivers consistent pressure and deeper muscle relief from head to seat.

The L-Track structure enhances the overall massage experience by improving spinal alignment and helping to relieve tension in both the upper and lower body. It ensures you get a full-length, therapeutic massage every time you sit down.

Wireless Charging Pad and Quick-Access Joystick

Stay charged and in control with the Kyota Yutaka M898’s built-in wireless charging pad and intuitive joystick.

The wireless charging surface, located on the armrest, lets you power your compatible smartphone during your massage—no cords needed. 

Meanwhile, the joystick offers quick access to essential functions like adjusting the recline and selecting auto programs, so you don’t always need the remote. This convenient layout helps you stay relaxed and fully immersed in your massage session.

 Together, these features blend modern technology with thoughtful design, adding an extra level of comfort and functionality to your daily wellness routine.

Intelligent Voice Command + Control

The Kyota Yutaka M898 offers a built-in voice command feature that allows you to control key massage functions using simple voice prompts.

This hands-free system responds to natural phrases, making it easy to start a massage, change programs, or adjust settings without needing to reach for the remote. It adds convenience and accessibility, especially when you’re already reclined and relaxing.

Whether you want to activate a specific routine or stop the session, just speak, and the chair responds. Voice control enhances user interaction, streamlines the experience, and supports a more effortless, personalized approach to in-home massage therapy.

Top Features of the Osaki Flagship Duo

Intelligent Health Management

The Osaki Flagship Duo features intelligent health monitoring that gathers five key body metrics to optimize your massage.

These readings include real-time assessments that the system uses to determine tension zones and stress levels. Using this data, the chair recommends personalized massage programs tailored to your needs.

Visual indicators on the remote display help you identify where tension is concentrated, allowing the chair to target those areas more effectively.

This smart integration ensures a more customized and beneficial massage, adapting automatically to your body’s condition with every session for a truly intelligent, data-informed relaxation experience.

Next-Level 4D + 3D Roller Mechanism

The Flagship Duo combines both 4D and 3D massage mechanisms to deliver an elevated experience that exceeds conventional chair designs.

This advanced technology allows complete control over roller depth, speed, width, and intensity. The 4D functionality includes variable speed to replicate human-like massage pressure changes, while the 3D aspect adjusts roller depth into muscle layers.

The system adapts in real time, responding to your body’s tension and contours to maintain consistent, lifelike pressure.

This combination allows for an exceptionally realistic and effective massage, providing precision and comfort tailored to your specific muscle groups and preferences.

SL Flex Track System

Unlike traditional massage tracks, the SL Flex Track system in the Flagship Duo maintains a fixed angle relative to the backrest, allowing for more adaptable and comfortable movements.

This innovative design provides enhanced spinal alignment and flexibility, helping the massage rollers stay in constant contact with your body’s natural curves.

Covering areas from the neck and shoulders to the hamstrings, the SL Flex Track offers full-body support and a deeper stretch.

Its dynamic structure improves effectiveness in key problem zones like the lower back and calves, giving users a more customized and therapeutic massage experience.

2-Stage Zero Gravity

Inspired by NASA's zero gravity technology, the Osaki Flagship Duo offers a 2-stage reclining system that helps distribute your body weight evenly and reduce spinal pressure.

The first stage provides gentle recline, while the second elevates your legs above your heart for a deeper sense of weightlessness.

These positions improve blood circulation, ease pressure on the spine, and enhance the effectiveness of each massage. Easily controlled through presets or manual settings, this feature promotes deeper relaxation and greater physical relief.

It’s ideal for anyone seeking a stress-reducing, gravity-free sensation that supports comfort and health during every session.

Heating Therapy

The Flagship Duo uses cutting-edge graphene heating technology to apply targeted warmth to the lower back and soles of the feet.

Graphene conducts heat quickly and evenly, ensuring a consistent temperature that helps loosen tight muscles, relieve soreness, and promote circulation.

The gentle heat complements the massage function, amplifying its effectiveness and helping the body relax more quickly.

 Whether you’re using it after exercise or a long workday, this dual-zone heating system provides restorative comfort where it’s needed most.

It’s a perfect enhancement to your massage session, especially during colder months or for users with chronic tension.
