Relaxonchair [MK-IV] Zero Gravity Shiatsu Chair Review (2019)

You’ve heard of “Zero-gravity” massage chairs that seem to be all the rage now.

But how does one differentiate between posers and products that are the real deal?

Relaxonchair [MK-IV] Zero Gravity Shiatsu Chair has sold enough units to put the brand under the radar of massage chair enthusiasts.

Will this model prove to be right for you as well?

Don’t bank on it!

I’ve extensively tested the model for comfort, features, and therapeutic benefits, and made some interesting discoveries.

Read this complete guide to know more.

After all, a home massage chair such as this is quite the significant investment.

About the Company (Relaxonchair)

Relaxonchair is a California-based company and brand that operates from Anaheim.

It was set up by a team that wanted to create a lineup of affordable massage chairs.

They aim to efficiently deliver their product to the customers without having to rely on third-party retailers or online portals to do the job for them.

FDA Registered In USA

Their massage chairs have been certified by the FDA as a registered medical device and are progressively improved upon for quality control.

The brand prioritizes customer-satisfaction as a measure of success and seeks to perfect their products based on consumer reports and reviews.

They claim to thoroughly test their chairs before dispatching them on the market and offers an efficient customer care service for any clarification.

About the Chairs

The Relaxon massage chairs are affordable than most other brands of the same products.

Although these provide you a good massage experience, we noticed that they do fall short by a few notches as far as features are concerned.

To understand this better, let’s take a quick look at the standout features of these chairs.

The brand offers two main models of massage chairs, namely, the Relaxonchair MK-II Plus and an upgraded version which is the MK-IV Zero Gravity Shiatsu Chair.

RelaxOnChair MK IV

In this particular guide, we have brought you an extensive review of the MK-IV ZG massage chair so that you get to know about the products better. 

Zero Gravity Setting- In the zero-gravity position, your knees remain elevated slightly higher than your heart, putting the entire body over the back.

The rollers can deliver a deep tissue massage to the body in this position.

This chair offers 3 seating positions for the ZG feature.

Heat Settings- The model provides heating in the lumbar region that extends slightly up to the mid-back.

It doesn’t have heat settings or controls to manage the heat intensity.

Airbags- The chairs have total 28 airbags (8 for the arms and hands and 20 for the legs and feet) that provide compression air massages by inflating and deflating to the limbs.

However, apart from the hands and legs, this model does not have airbags or cells for the shoulders, back, hips or the neck.

Preset and Auto Massages- The MK-IV comes with 5 preset massage features for you.

Five ProgramsThis includes massage techniques like Shiatsu, Kneading, Tapping, Knocking and Combination Kneading and Tapping.

However, the air pressure intensities are not customizable, and the rollers are only adjustable while using shiatsu, tapping or knocking techniques.

The chairs also bring 5 auto massage programmes namely, Relax, Comfort, Recovery, Neck, and Shoulder, Back and Waist.

Extended S-Track- This chair comprises of an extended S-track mechanism that is supposed to be longer than the conventional S-track in massage chairs, if not as long as the L-tracks.

Full Body Scan- This model comes with a full body scan technology that locates all the afflicted areas of the body and directs the massage mechanisms towards them.


The model provides a considerable amount of benefits. Each of its features contributes to the overall massage experience.

Zero Gravity PositionThe zero gravity feature puts the entire body to rest and brings in the total body weight into play.

It improves blood circulation in every part of the body and boosts up lung capacity.

It also helps in treating insomnia and other sleep-related issues.

The heating and massage rollers pair up together to deliver deep tissue and complete body shiatsu massages.

This helps to relieve chronic aches in the back and especially in the lower back region.

The heat taps the energy into the tissues and muscles and revitalizes the body and senses.

The pre-set and automatic massages combine to give you an ultimate massage experience.

These techniques not only massage your limbs, but help open up blocked veins, blood vessels, and pressurized muscles.

Deep Massage And HeatThe chair helps deliver compression air massages to your arms, forearms, hands and the legs.

This help activates and massages the pressure points located throughout these regions.

This instantly de-stresses the entire body and releases muscle tension.

This greatly facilitates the blood to flow freely in the clogged up regions and repair worn-out tissues.

The Full Body Scan helps to detect every complicated area and pressure spot in the body and enables the rollers to work on these.

Significant Drawbacks

We did mention before that despite having a few attractive features; the MK-IV does fall short in its attributes.

It fails to achieve maximum consumer satisfaction than some of the models that we think have it all sorted.

  1. No Separate Foot Rollers or Massagers

The Relaxonchair MK-IV does not include any foot roller or massager which is one of the most vital features that is necessary for a complete massage experience.

The model just has airbags for the legs and feet that give you a regular air compression leg massage.

This does not really do much for the soles of your feet or the pressure points on your toes.

  1. Has an S-Track Massage System

This model consists of an extended S-track system that the brand claims to be longer than the conventional S-tracks.

S-Track SystemAlthough, the track in this chair maybe a tad bit more efficient in reaching down to the farthest levels of your lower back, it doesn’t really provide much out of the ordinary.

So, we wonder if the word “extended” is a marketing tactic to sell off a regular S-track massage chair.

But, in all respects, we would much prefer a good L-track that goes down to the very glutes and thighs to massage those areas.

  1. Limited Heating Area

Limited Heating Area

The company claims to put in a heating system in this model that affects the mid-section of the back. 

But when we tried the feature, we found that the heating is MOSTLY limited to the lumbar portion with maybe a marginal effect on the surrounding areas.

Additionally, this model does not have any heating facility for the seat, legs or anywhere else for the body.

  1. No Vibration Feature for the Seat or Head Massages.

The seat vibration feature is a sought-after characteristic in a massage chair that provides the benefit of relieving lower body joint pains and greatly calms the body.

We greatly missed this feature in this model which doesn’t even provide a simple heat setting for the seat.

Additionally, this model neither has a head massager nor, any system to massage your shoulders.

A Better Alternative?

Since we weren’t entirely satisfied with the overall performance of this model, we decided to provide you with a better alternative.

Our pick would be the Kahuna LM6800 Massage Recliner which we think does the job twice as good.

Kahuna LM6800

The features and benefits of this have been discussed for you below.

  • This model offers 3 zero-gravity positions that deliver an ultimate “floating in outer space” sort of sensation.
  • It consists of an L-track design with 2D rollers that provides a thorough neck to glutes massage.
  • It comes with a vibratory seat feature that treats lower-body ailments.
  • This model also has heating facilities in the calf region along with the usual lumbar portion which provides instant relief from chronic and acute aches.
  • It offers you the benefit of 6 preset massages with a 30 minutes timer button.
  • The model comes equipped with dual foot-rollers for satisfying foot massages and a detachable footrest that can be easily cleaned.
  • The unique Yoga-stretch feature of this chair stretches the front of your body, spinal column and hamstrings to release any tensed vein or muscle.
  • It comprises 36 airbags with 3 customizable levels that provide you with a full body air massage.
  • It features a full body smart-scanning facility for locating afflicted points and involves superior noise reduction technology that allows you to enjoy your massages peacefully.

Why Buy This Model?

The Kahuna LM6800 Massage Recliner does not only give you a wide range of attractive features, but it also gives you better versions of the attributes that you will get in your Relaxonchair MK-IV model.

It doesn’t exceed much in what you pay for the MK-IV model but gives you a better massage experience.

Kahuna FDAAdditionally, the Kahuna model has a much better material quality that the MK-IV and has a stronger built and design.

It also comes with proper warranty documents and users’ manual instructions for assembly at the time of purchase.

It is a space-efficient model and has been certified as a medical device by the FDA.

We do think that this massage recliner is overall a better alternative than the Relaxonchair MK-IV massage chair.

Where to Buy?

The best place to buy the Relaxonchair MK-IV massage chair is on its official website page that lists the price along with the image of the model.

But, I honestly believe Kahuna would be an overall better choice.

Also, please take notice that as of 2018, Amazon offers the best price deal for the Kahuna LM6800 Massage Recliner than eBay or any other online shopping portal.

And as a bonus, you also get the Amazon seal of warranty. What can be a better deal than this?
