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

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?

Now replaced with RELAXONCHAIR [MK-V] model with Space-Saving Design

Don’t bank on it!

I’ve extensively tested this chair model for relief, 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 a significant investment.

About the Relaxonchair MK-IV Review

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

Although these provide you a good 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 namely, the MK-II Plus and an upgraded version which is the MK-IV Zero Gravity Chair.

RelaxOnChair MK IV massage chair

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 massage 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 a total of 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 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 tapping, or knocking techniques.

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

Extended S-Track- This massage chair comprises 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.

Benefits of Relaxonchair

The model provides a considerable amount of benefits. Each of its features contributes to the overall relaxing 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 massage chair helps deliver compression air massages to your arms, forearms, hands, and legs.  This helps 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 for superior relaxation.

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 massage 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.

Below is another popular model from the same brand: RELAXONCHAIR [MK-II PLUS] Full Body Zero Gravity Massage Chair with Built-in Heat and Air Massage System. It features BUTTLOCK L-TRACKING MASSAGE System, DEEP TISSUE MASSAGE & FULL BODY STRETCHING: SYSTEM, LOWER BACK HEATING.


A Better Alternative to Relaxonchair Massage Chair?

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 well.

Kahuna LM6800

About Relaxonchair MK-VIII

The Relaxonchair MK-VIII convertible is another one-piece steel frame that I’ve been test-driving for some time. It has a larger 6.5 feet long (measuring it from the front corner to the back is about 6.3 feet) and 7.9 inches wide at its widest point. The cargo storage compartment has no knee braces or straps, so you’ll need a lift for the seats and the compartment, and have to use two “Liftsticks” for storage. The relief and Classic models have “Auto-Lock” and “Self-Locking” variants with one fixed cargo handle and one swiveling cargo handle, and they also have a “Lift-a-thon” feature where you can turn your arms upside down to pick up cargo.

The front of the seat is slightly higher than the back of the seat, so when you raise the front, the back of the seat will slide backward. The back cushions are about 2.5 inches thick and have 4 layers of padding. The comfy model has a good side and back angle. I found it easy to put on and adjust. On the comfy model, the headrest tapers from being slightly soft on top, to the firm on the sides and back. The comfy model also has a back adjustment strap at the headrest. The lift-a-thon is available only on the comfy model, with the Auto-Lock, built-in heating, and Self-Lock versions.

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 user-friendly features that you will get by buying the this 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 than 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 and I highly recommend it.

Where to Buy?

The best place to buy the Relaxonchair MK-IV massage chair is on its official website page (they also offer a white glove delivery option ) that lists the price along with the images and model features and special offers.  But, I honestly believe Kahuna would be an overall better choice.

Also, please take notice that as of 2020, 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?
