The Johnson Wellness J6800 vs the Synca Kagra

When comparing massage chairs, especially fairly expensive chairs, for your purchase the features they provide and the massage offered is going to be the largest part of your purchase decision. When you look at the Johnson Wellness J6800 and the Synca Kagra, understanding what sets them apart can make choosing between these $4,999 massage chairs much easier. These chairs provide an S-Track or L-Track massage, and there are some supplementary features that differ as well.

Let’s take a look at what these specific chairs offer.

Johnson Wellness J6800

The Johnson Wellness J6800 massage chair delivers a deep tissue massage above that of the standard massage chair. The advanced mechanism takes a 3D massage further by allowing the rollers to adjust their rhythm and pressure actively during your massage. This advanced 4D movement provides a more lifelike massage experience. The J6800’s foot and calf massage unit easily flips to an ottoman or tucks away to make the chair more like a traditional recliner.

4D Massage

Like the 3D massage roller, the 4D massage is able to move up and down and in and out. The in and out motion adds another humanistic movement to the kneading and is controlled through adjustable intensity. The Japanese designed the 4D massage roller of the Johnson Wellness J6800 to add adjustable speed to the movement of the rollers.

Dual Massage Heads

Many massage chairs on the market use a quad style roller. The best high-end massage chairs use a dual massage head system instead of the Johnson Wellness J6800 massage chair. The dual-head allows for more massage techniques and more precise superior deep tissue massage.

Body Scanning

The body scan technology uses up to 11 different pressure points to tailor your massage experience to fit the shape of your neck, shoulders, and back. This way the chair knows where your shoulders are and can adjust accordingly.

Convertible Ottoman

This chair’s ottoman flips inward to hide the calf massager, making it ideal if you plan to use your massage chair as a recliner as well, or if you need the calf massager to be inactive while you’re using it.

Memory Programs

There are three memory slots that you can program and save for later. Once saved, you can press a button to recall that massage to use over and over.

Foot Heat Therapy

The Johnson Wellness J6800 massage chair offers two heat pads, one in each foot. The heat helps to remove tension and relax muscles.

Heating Pad

There is also a heating pad that you can use to create the maximum therapeutic benefit on your back or wrap it over your shoulders, arms, and hands.

Air Compression Massage

The Johnson Wellness J6800 massage chair is equipped with 31 airbags in the arms, hips, shoulders, thighs, calves, and feet. The Pulse Air Massage system enhances circulation to relax your body while offering relief to painful areas.

Auto Programs

Eleven automatic programs provide therapeutic relief. You’ll find Refresh, Relax, Shiatsu, Morning, Night, Stretch, Energize, Shoulder, Lower Back, Quick, and Music Sync programs in the menu.

Massage Techniques

There are also nine different massage techniques including kneading, tapping, rhythm tapping, kneading & tapping, shiatsu, rubbing, rolling, sideways kneading, and up-down kneading. You can choose a full body massage and choose to focus on one specific area.

Music Integration

You can connect any music player to the auxiliary jack and play music through the chair’s speakers in the headrest. There’s even a sync program that syncs the massage motions to the beat of your music.

Adjustable Footrest

The footrest utilizes airbags to massage your calves as well as the instep and soles of your feet. The Shiatsu nodes on the bottom work with the airbags to create a fantastic experience. Plus, the footrest also extends six inches to accommodate taller users.

Power Recline & Ottoman

With the touch of the button, recline the chair to 160 degrees. You can also raise the ottoman to put you in the perfect position for massage and relaxation.

Auto Recline Armrest

When you recline the massage chair, the armrests follow to ensure proper placement of your arms during your massage.


The J6800 offers adjustable intensity through five levels from light to deep tissue. The airbags have three levels of strength adjustment. You can also adjust the roller width from narrow to wide to accommodate almost anybody. You can also entirely turn off sections of the airbag massage.

Remote Control

The remote is a handheld LCD-style controller that’s very straightforward and simple to operate. The display shows you active programs and roller position. Plus, you’ll see the time left on your massage.

Now let’s look at the Synca Kagra.

Synca Kagra

synca kagra 4d feature set

The Synca Kagra 4D Premium Massage Chair is a Japanese engineered massage chair that’s powered by 2nd generation software that uses 78 massage techniques and specialized stretch software. The Kagra features a Bluetooth audio system, pulsing shiatsu foot massage, fingertip controls, precision neck massage, triple region heat, and zero gravity. This chair also features a reversible ottoman so that you can use it like your favorite recliner and stream your Bluetooth enabled tv’s audio through the chair while you relax worry-free.

Luxurious Color Variations

There are three classic colors that can blend perfectly with your home decor.

Zero Gravity

The Kagra features zero gravity that maximizes the effectiveness, efficiency, and comfort of your massage. Zero gravity puts your body in a neutral posture, allowing the chair to work its magic and improving circulation by raising your legs above the level of your heart.

4D Massage

4d massage rollers

The 4D technology provides precise massage with the ease of auto programming. The chair can deliver multiple Shiatsu techniques through superior execution that uses rhythmic vertical, width, and depth motions that mimic human hands.

Body Scan

Real body sensing customizes how the massage proceeds, adjusting to your unique size and shape. Through high-performance dual-layer sensors, the Kagra delivers a customized massage experi­ence contoured to each individual’s body.

Ergonomic Massage Posture

The Karga armrest automatically adjusts as the chair reclines to ensure full contact with all massage surfaces. It maintains an ergonomically correct position for your entire body.


The unique upper body heating feature is in the form of a heating pad that can lay behind you to heat your back or go in front of your chest and stomach, even warming your hands with its pockets. Add in the foot and calf heat and you’ll be warm all over, increasing your relaxation and circulation.


As you know, you can sync up your Bluetooth player to enjoy listening to anything you want during your massage. You can even pair your smart TV and watch your favorite movie.


rotating ottoman

The adjustable footrest with a multi-functional rotating ottoman can be used for three purposes- foot and calf massage, ottoman like a recliner, or stored to save space and look nice. This adjustable footrest articulates to extends and change angles to accommo­date users with different heights, so everyone can enjoy the chair.

Finger Tip Controls

With the Kagra it’s easy to change incline and recline with the shortcut keys at your fingertips. You can adjust the backrest and footrest angles, massage intensity, and select or change the preferred courses, all with one finger.

Deciding Factors

the best choice for you

When choosing between these two chairs, the massage experience you’re searching for is the most important factor in your purchase. 

These chairs in particular offer very similar massages with 4D technology, all-over heat, foot rollers, and rotating ottomans. The main difference is that the Kagra offers fingertip controls and zero gravity whereas the J6800 offers memory options and dual massage heads. The massage you receive from either chair will likely be very similar and the few extra options might be a small detail that makes up your mind for you.

What it all comes down to, as it does with most purchases, is your personal preference in a massage. What experience are you looking for and what chair delivers that experience for you? If you have the chance to try out either chair, we’d recommend it because they are so similar. This will be the best way to tell if one is more comfortable or more effective for you personally.
