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

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.
Adjustability
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
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

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.
Heat
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.
Bluetooth
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.
Footrest

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

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.
