Main Distinguishing Features

The Osaki OP-4D Master Massage Chair comes packed with advanced features that set it apart from other massage chairs. Here are some of its main distinguishing features:

4D Massage

The Osaki OP-4D Master features our next-generation Massage Rollers which deliver a much deeper tissue massage. By moving the two individual massage mechanisms in multiple directions, the rollers are designed on an extra plane of movement that allows them to relieve your back region with 5 different levels of adjustment for the 4D massage, 4 levels of intensity and 3 of width. The Master is not as intense as the Highpointe or the Maestro line.

SL Track Technology

With the Osaki OP-4D Master, you get the best of both worlds--the precision of an S-Track that perfectly follows the curvature of your spine with the extra coverage of an L-Track which will then wrap around the glutes giving you a more comprehensive and thorough massage experience. 

Proprietary Shoulder Massage

The Osaki OP-4D Master provides a relaxing massage for your upper back, neck, and shoulders. The 20 shoulder airbags in the Master massage are contoured to your shoulders to provide a relaxing and rejuvenating massage.  There is also a finger node that comes out and over your shoulders to apply direct pressure into that frequent trouble area.

Body Pain Scan

The Osaki OP-4D Master makes use of its insightful health pro program to identify any stress in the back area, as everyone is built differently and has distinct requirements. After the scan is complete while you hold the sensor, the Master will utilize the information to create a massage routine just for you.  You'll be able to see the color-coded back map to see where you are holding your stress and then sit back and enjoy the massage the Master creates in order to address all of your issues. This system is very similar to the Chair Doctor.

Smart Voice Control

The Osaki OP-4D Master includes an intelligent voice recognition system which will allow you to control the chair with your voice similar to the way that Alexa works. Voice or speech recognition is the ability of devices to record spoken words or commands by the user.

Body Scan

The Osaki OP-4D Master will perform a thorough body scan in order to accurately map the key areas of the neck, shoulders and spine to fully customize the experience to your body and ensure the optimal amount of pressure is applied during the massage.

Zero Gravity

Inspired by NASA, the Zero Gravity position is the perfect position for ultimate relaxation. By bringing the legs up in line with the heart, all pressure is removed from the spine creating a near weightless experience. This will enhance the overall massage experience and eliminate any spinal compression.

Full Body Air Massage (46)

There are 46 airbags located throughout the Osaki OP-4D Master to offer a full body massage experience. Airbags are located at the shoulders, arms, waist & pelvis, calf & feet areas to increase blood flow throughout the body. The gentle compression helps to stabilize you during the massage and works synergistically with the rollers to relieve pain and tension.

Foot & Calf Rollers

There are spinning reflexology rollers placed beneath the feet of the Osaki OP-4D Master which provide an outstanding foot massage. The rollers will travel along the sides and middle of your feet to provide a more thorough kneading experience which will hit all the acupressure points that are often neglected during our daily activities. Along with the foot rollers, the calf airbags will inflate to initiate a calf kneading massage.

Extended Heat Therapy (Lumbar, Feet)

The Therapeutic Heat function of the Osaki OP-4D Master Massage Chair is located around the lumbar and foot region and provides soothing relief from chronic lower back pain. Heat therapy helps ease draw blood to the area, decrease tension and stress, relieve arthritis pain, and heal sore muscles. Plus, we happen to think that it just feels good on a cooler day.

16 Auto Programs & 4 Manual Styles

The Osaki OP-4D Master comes equipped with 16 different automatic programs These auto programs combine the 4 different massage techniques available in the chair. These 4 massage styles are Kneading, Tapping, Rolling, and Shiatsu.

Space Saver (3")

Along with the Zero-Gravity recline, the Osaki OP-4D Master comes standard with space-saving technology, that allows you to place the chair within 3 inches of the wall, even while fully-reclined. The chair will move out first and then up while moving into Zero-Gravity.

Quick Controls

The engineering team behind the Osaki OP-4D Master thought of every little detail to make this chair the most thoughtfully designed and user-friendly chair possible. With quick controls, everything is just a quick touch away--including your phone's battery life.

Touchscreen Tablet
