Kahuna EM-8500 - The King's Elite Massage Chair Features

Full Body Massage Care HSL-Track

The Kahuna EM-8500 is one of the few stationary massage chairs to feature a flexible HSL-Track or Hyper SL-Track massage system. This type of roller track comes with several benefits over the traditional S-track or L-track roller massage system.

It uses a combination of spinal curve adaptability of the S-track and the extra length of the L-track till the hamstrings of the user. The length and curvature of the roller massage system allow the chair to reach all parts of the back and every pressure point effectively and accurately for a great massage experience.

Full Body 4D Roller Massage System

Speaking of the roller massage system, the Kahuna EM-8500 is equipped with a 4D roller massage mechanism. This allows the users to customize their massage from robust to delicate, mimicking the human touch. The 4D rollers in this chair massager can travel sideways, vertical, and also in and out for a deep tissue massage experience.

Additionally, there are rollers in the calves and feet region as well, for a full-body roller massage. There are five levels of 4D massage force for flexibility. It also offers rolling speed and 5-level air pressure for further modification of the massage experience.

3-Level Zero Gravity Recline

The Kahuna EM-8500 chair massager comes with 3 levels of zero gravity recline for extreme comfort. Thanks to the automatic body scan, the chair can detect your body type and select the best possible zero gravity angle for your massage. The zero gravity position is designed by NASA to relieve the pressure on the spine of astronauts during the takeoff and ease circulation in the body.

The zero-gravity recline serves the same purpose in the massage chair, which is to relieve your spine and boost circulation in the body for enhanced relaxation. Additionally, the zero-gravity recline makes hard-to-reach pressure points more accessible to the back massage chair.

King’s Elite Massage Programs

The Kahuna EM-8500 massage chair comes with 24 pre-programmed massage modes divided into Classic, Specialty, and Elite Target categories. The Classic category comprises Renew, Refresh, Recover, Stretch, Morning, Night, Anti-Stress, and Energize modes.

The Specialty category includes Salesman, Housewife, Office Clerk, Game Player, Driver, Sports Man, Server, and Senior. Lastly, the Elite Target category includes Neck, Back Relief, Waist, Neck & Shoulder, Waist & Hip, Leg Feet, Upper Body, and Lower Body.

Ondol System Heating Therapy

The Kahuna premium chair massager comes with an Ondol System for thermotherapy. Heat therapy is imparted by infrared heating pads located in the lumbar, calf, and feet region. Heat therapy is designed to boost the massage effectiveness by loosening up taut tendons and muscles. Additionally, the heat also promotes better circulation in the body. This is one of the best heat and massage chairs available in the market.

Negative Ion Diffuser

This premium chair massager has a negative ion diffuser integrated into the headrest. Negative ions have multiple benefits with mood upliftment, anti-depressant, and better sleep being the prominent ones. Simply slide into the chair and enjoy a greater sense of relaxation while getting the best massage experience of your life.

Bluetooth Speakers

The chair also comes with built-in Bluetooth speakers. It allows users to connect their smartphones or tablet with the speakers wirelessly. This way users can enjoy music, audiobooks, or podcasts while getting massaged.
