Massage Chair Comparison: JPMedics Kumo vs Kahuna EM-8500

Massage Chair Comparison: JPMedics Kumo vs Kahuna EM-8500

Trying to pick the right massage chair for your home or office (or home office) can be a little intimidating once you realize how many different chairs are on the market. Since you can expect to be spending at least several thousand dollars on a chair, let us help you make your list of potential buys a little bit shorter and more informed.

The Kahuna EM-8500 massage chair and JPMedics Kumo massage chair both have a number of great features to help you relax. Below, we'll go over the pros and cons of each chair to help you make your decision.

What are some Top Features of the Kahuna EM-8500 Massage Chair?

Let's start this comparison off by talking about the features found on the Kahuna EM-8500 massage chair. This chair comes with a two-year parts and labor warranty and arrives fully assembled, so you can quickly and consistently enjoy all of the features that the EM-8500 has to offer.

Zero Gravity Positioning and Space-Saving Technology

Kahuna EM 8500 Space Saving and Zero Gravity

The EM-8500 comes with zero gravity positioning, which allows you to recline the chair to your desired position and get optimal relaxation and comfort from your massage. Having the ability to recline to your desired position can help enhance your circulation and lessen your swelling too, which is absolutely ideal if you are someone who has a condition like lymphedema.

In addition, the Kahuna EM-8500 is equipped with space-saving technology, allowing you to maximize the amount of floor space in your room.

4D Massage Rollers
One of the features that attracts buyers to the Kahuna EM-8500 over other massage chairs is that it has 4D massage technology. Other chairs often have 2D or 3D, but these 4D massage rollers allow you to change the intensity of your massage. Simply use the touch screen remote on the chair to set the 4D massage rollers to the intensity you desire.

They can move in almost any direction you choose, which is what makes them so unique. Most massage rollers will only move in a set number of directions, potentially not reaching all of your problem areas.

Bluetooth-Capable Speakers
Want to mellow out to your favorite tunes? Just sync up the speakers with your smartphone for a personalized massage experience. The speakers are positioned on each side of your head so that you can easily hear without any distractions cutting in.

Not all chairs in this price range come with Bluetooth speakers, so having them feels like quite the treat.

Heat Therapy

Kahuna EM 8500 Heating Therapy

Are your muscles extremely tense? If so, you can simply turn on the heat therapy function and let it go to work on your most distressed muscle groups. This allows your muscles to relax as the massage works deeper into these muscles. It makes for an enjoyable experience if you are someone who has a lot of knots or holds a lot of tension along their spine.

What are some Top Features of the JPMedics Kumo Massage Chair?

The JPMedics Kumo likewise has a long list of features that aim to maximize your massage experience. You get things like full back coverage from the L-track, 4D heated massage rollers, an advanced back-scanning sensor, heated knee and calf therapy, and an advanced reflexology function.

Let's talk a little more in-depth about what each one of these features can do for you.

L-Track Full Back Coverage
Everyone's spine is different. Some are slightly longer than others. Some have degeneration or damage from illnesses or accidents. A massage should be customizable, right? Well, the JPMedics Kumo massage chair offers you customization with its L-track technology.

This design gives you full back coverage, going wider and reaching even more trigger points. The L-track can massage from your neck muscles all the way down to your glutes.

4D Heated Rollers

JPMedics Kumo 4D Heated Rollers

Like the Kahuna EM-8500 massage chair, the Kumo has 4D rollers. These rollers are heated and protrude three inches deep and travel at one and a half inches apart from each other. This gives you a more accurate spinal massage and hits your specific acupuncture points.

Also, the heat coming through from the rollers is designed to simulate the warmth of real hands massaging your muscles.

Advanced Back-Scanning Sensor
The advanced back-scanning feature offers sensors inside the rollers and features state-of-the-art computer technology. This system detects the unique shape of your spine and will help in catering to your body type.

Heated Knee and Calf Therapy

JPMedics Kumo Heated Knee and Calf Therapy
The JPMedics Kumo is a stand-out chair for being the very first to feature 3D knee technology. This system combines heat therapy and air compression in order to massage your knees.

The thermal airbags are specifically fitted and can be adjusted to create a more personalized experience. Just press the button, and the airbags will compress down to your calves.

Advanced Reflexology
This chair's tri-action foot rollers utilize two levels of shiatsu foot rolling, and this gets combined with an air pressure massage function. Together, this creates a deep tissue foot massage that hits all your core reflexology points in the feet.

JPMedics Kumo Pros and Cons


  • Made in Japan
  • L-track design
  • 4D heated rollers
  • Advanced back scanning sensor
  • Reflexology massage rollers

JPMedics Kumo Massage Chair

Available Programs
Let's talk about which programs each chair has available, starting with the Kahuna EM-8500. This chair comes with classic auto programs (renew, refresh, recovery, stretch, morning, night, anti-stress, and energize), specialty auto programs (salesman, house wife, office clerk, game player, driver, sports man, server, and senior), and elite target programs (neck, neck and shoulder, back relief, waist, waist and hip, leg feet, upper body, and lower body).

The JPMedics Kumo massage chair comes with eleven auto massage programs and 500 customizable options. Massage techniques include knead, tap, Swedish, clap, shiatsu, and rolling. There is even a chromotherapy function that uses LED light therapy in order to improve your mood, increase bodily detoxification, and promote a healthy metabolism.


Whether you choose the Kahuna EM-8500 or the JPMedics Kumo, you will be getting a relaxing massage experience. The Kumo costs more, but its abundance of features are downright impressive. Chromotherapy is something that those with mood issues might find truly beneficial. And the heated knee therapy function is certainly helpful for anyone with joint pain or other conditions that cause pain in the knees.

Your buying decision will likely boil down to how much room you have in your budget. If your budget is rather expansive, we would pick the JPMedics Kumo. However, if you don't have as much money set aside for a massage chair, the Kahuna EM-8500 is a great chair with plenty of advanced features.
