*Human Touch has engineered and patented much of the technology they use in their chairs. If some of the terms — FlexGlide, BodyMap PRO, FigureEight, etc. — don’t make sense now, don’t worry. We’re explaining each feature below.

In this Human Touch ZeroG 5.0 review, we’re taking a look at three ZeroG massage chairs: 2.0, 4.0, and 5.0. First, we’re showing all of their features in a side-by-side comparison chart. Then, we’re explaining what each feature is below to see what these massage chairs have in common, what sets them apart, and which is the best value for the money. Let’s get started!

Who is Human Touch?


Human Touch is a massage chair company based in Long Beach, California. For over 35 years, they’ve been producing innovative massage chairs with a focus on aesthetics — designing chairs that are not only therapeutic but match the modern home. Their massage chairs have received numerous Design Journal Awards for Design Excellence (ADEX).

Also, they are the only ones recognized by the World Federation of Chiropractic as being valid complements to back therapies. Although Human Touch’s design, customer service, and engineering take place in their headquarters, the massage chairs are manufactured in China.

Today, we’re focusing on the Human Touch ZeroG 2.0, the Human Touch ZeroG 4.0, and the Human Touch ZeroG 5.0 massage chair from the WholeBody Series. The ZeroG 2.0 costs around $1300 and both the ZeroG 4.0 and ZeroG 5.0 cost around $3300.

Common Features of the Human Touch ZeroG 5.0, 4.0, and 2.0 Massage Chairs


The Human Touch ZeroG 2.0 massage chair was the first one introduced by Human Touch, followed by the ZeroG 4.0 and ZeroG 5.0 models. With each new model, Human Touch incorporated new features. So the 4.0 has more features than the 2.0, and the 5.0 has more features than the 4.0. Even so, the ZeroG massage chairs share some common features, including:

Retractable and Rotatable Ottoman

The ottomans on the Human Touch ZeroG 2.0 Immersion massage chair, ZeroG 4.0, and ZeroG 5.0 are all rotatable. They’re also all retractable.

In its standard position, the ottoman sits retracted under the seat. But using the arrows on the remote, you can raise the ottoman to use as a footrest. Or, use the rotation release lever to rotate it to reveal the calf and foot massager.

This feature gives you more control over how you use the ottoman and how your massage chair looks when not in use. Instead of always seeing the calf and foot massager, you can rotate it to reveal a smooth cushioned surface.

Or, instead of only having one use (as a massager), you can rotate the ottoman to use it as a footrest. Lastly, instead of always having a footrest, you can retract it altogether and hide it under the seat.

Features like the rotatable and retractable ottoman help the chairs pull double duty as luxury recliners and massage chairs — enhancing their everyday usability.

FigureEight Massage Technology


Inside the calf and foot massager on all three chairs is Human Touch’s patented FigureEight massage technology. So what is FigureEight technology? To understand it, we first have to understand the massage components in the ottoman.

Most massage chair manufacturers use airbags in their ottomans. Human Touch, on the other hand, doesn’t. Instead, Human Touch uses paddle massagers molded from a durable rubber-like material. Without them, FigureEight technology would not be possible.

Airbags and paddle massagers operate from a very different set of rules. Airbags are dependent on air. They inflate and deflate, compress and release. Although they can inflate at different intervals — one airbag inflates while another deflates — their movements are limited. Paddle massagers, however, are not limited by air. They can compress, release, and produce progressive movements — as a singular unit.

So back to our question: What is FigureEight technology? FigureEight technology describes how the paddle massagers move which is an upward wave-like motion.

Starting from the feet, the paddle massagers roll up the calves circulating blood toward the heart. As blood moves from the feet, new nutrient and oxygen-rich blood enter the calves and feet. Since the paddle movement is progressive (always moving up), the circulation in the calves and feet is never blocked — even when pressure is applied.

Zero Gravity Immersion Seating


As their name implies, all three massage chairs feature Zero Gravity.

Equally as popular as it is misunderstood, Zero Gravity doesn’t actually make you feel weightless. It does, however, evenly distribute the weight of your body so that the backrest holds it, giving the sense of weightlessness.

Originally developed by NASA to minimize the stress of takeoff on astronauts, the position removes vertical stress from the spine and lower body while elevating the legs slightly above the heart to increase circulation. In the Zero Gravity position, your spine and the muscles in your neck and back can decompress and relax which not only produces a more intense massage, but helps restore proper posture.

Massage Techniques

The Human Touch ZeroG 2.0 immersion massage chair, the Human Touch ZeroG 4.0 immersion massage chair, and the Human Touch ZeroG 5.0 immersion massage chair all feature the same number of massage techniques: four.

The four techniques are Stretch, Ease, Tone, and Flex.

  • Stretch kneads your back in small circular motions.
  • Ease gently rolls up and down your back.
  • Tone combines circular kneading and rapid-tapping strokes. There are two speed settings for Tone.
  • Flex rapidly taps along the spine, replicating a technique used in sports medicine for deep muscle treatment. There are two speed settings for Flex.

Preset Massage Programs

The massage chairs also have same preset massage programs — or, auto-immersion programs as Human Touch calls them. There are four, including:

  • Refresh
  • Retreat
  • Relax
  • Sleep

Starting with Refresh, the programs move down in intensity. So, Refresh is the most intense and Sleep is the gentlest. Each program was designed with the help of the Human Touch Wellness Council, a group of wellness professionals like chiropractors, naturopathic doctors and sleep experts.

Manual Mode Options


If you want a more tailored massage, manual mode options give you control and allow you to customize settings like roller position, speed, zone, width, and range. They’re an important aspect to any massage chair, especially those that don’t offer any type of body scanning software — like the ZeroG models we’re reviewing.

In general, if you’re fond of making adjustments and want control over customizing your massage, pay attention to the what types of manual mode options are available. That way, even if you aren’t thrilled with the preset massage programs, you can always dial in a massage that works for you.

Let’s take a look at the customization options available on the Human Touch ZeroG 2.0 massage chair, the Human Touch ZeroG 4.0 massage chair, and the Human Touch ZeroG 5.0 massage chair.

  • Range lets you customize the vertical range of any massage program. There are five range settings on the ZeroG 2.0 and seven on the ZeroG 4.0 and ZeroG 5.0.
  • Width lets you adjust your massage width up to three settings from narrow to wide and works with the Flex and Ease massage techniques.
  • ​Position uses a set of up and down arrows that let you manually move the position of the rollers during any massage technique.
  • ​Zone concentrates your massage to a six-inch zone. Use the up and down arrow to select the desired area.
  • ​Calf gives you three calf massage speed settings or lets you add calf massage to any massage program.
  • ​Stop/Park stops your massage and moves the rollers to the top of the backrest.

Have a sore spot in the middle of your back? Let’s illustrate how you could use the manual mode options to customize a massage.

First, choose one of the massage techniques: stretch, ease, tone, or flex. Then, using the Position arrows, move the rollers to the sore spot. If you selected Flex or Ease, adjust the massage width. Or, use the Zone option to fix your massage to a 6-inch section. Continue adjusting until you’ve dialed-in your ideal settings.

Most of the manual mode options on the Human Touch ZeroG 5.0 massage chair (the most feature-rich of the group) are also on the Human Touch ZeroG 2.0 massage chair. And it’s a good selection considering the price point. Although they share most of the same manual mode options, the Human Touch ZeroG 2.0 immersion massage chair doesn’t offer any intensity adjustments.

The right-out-of-the-box intensity is what you get. Both the Human Touch ZeroG 4.0 massage chair and the Human Touch ZeroG 5.0 massage chair, however, offer intensity adjustments which we’ll cover later in the article.

Handheld Remote


All of the manual mode options, massage techniques, and preset programs are clearly labeled on the remote. The three chairs — ZeroG 2.0, ZeroG 4.0, ZeroG 5.0 — feature a similar remote: thick, handheld with buttons and no display screen. Each remote varies slightly from one model to the next because of additional features.

But, in general, they are identical in style. For example, in addition to having buttons on the front of the remote, the ZeroG 4.0 massage chair and the ZeroG 5.0 massage chair have buttons on the side. Although there are no display screens, the remotes are perhaps one of the easiest to use.

When you’re finished using the remote, place in it the storage pocket on the left side of the chair.

SofHyde Upholstery


On the outside of the massage chairs is Human Touch’s patented SofHyde upholstery, a leather-like material made from polyurethane. SofHyde mimics the look and feel of genuine leather.

However, it is durable and flexible enough to allow the rollers to move smoothly while providing consistent pressure across the back. It also gives the massage chairs the luxury recliner look — without the high price of genuine leather.

Sofhyde upholstery is easy to clean with a vacuum or a water-based cleaner. The Human Touch ZeroG 2.0 massage chair comes in two Sofhyde colors: black and espresso. Furthermore, the Human Touch ZeroG 4.0 and Human Touch ZeroG 5.0 massage chairs come in three Sofhyde colors: black, bone, and espresso.

Removable Padding


All three massage chairs feature a removable head pillow and massage-softening back pad. The padding gives you the option to increase the intensity of your massage by putting your neck and back in closer contact with the rollers.

To remove the head pillow, simply flip it behind the chair. You can remove the massage-softening pad by flipping the backrest pad over the top of the chair.

Open the zipper on the back of the backrest pad. Pull out the massage-softening pad. Close the zipper, flip the backrest pad back down and you’re ready to enjoy a more intense massage.

Keep the pad in a safe place in case you want to use it in the future. But if you do misplace it, replacements pads are available from Human Touch for an additional charge.

Space-Saving Design

Each massage chair only requires about 6 inches to recline fully. Compared to the foot or foot and a half needed by many other massage chairs, this space-saving design makes these chairs a great option for small spaces like apartments or offices.

Unique Features of the Human Touch ZeroG 2.0 Immersion Seating Massage Chair

Open-Toed Calf or Foot Massager


Let's go now to our Human Touch ZeroG 2.0 review. All three chairs feature a calf and foot massager ottoman. But the massager on theHuman Touch ZeroG 2.0 massage chair is very different. It’s open-toed. Instead of massaging the calves and feet simultaneously like the ZeroG 4.0 and ZeroG 5.0, the massager ottoman on the ZeroG 2.0 offers calf or foot massage.

Here’s how it works: Once you deploy the ottoman, rotate it using the rotation release lever on the right side to reveal the calf and foot massager. Rotate until the foot and calf massager is facing up. But, not so far that it “clicks” in place — it should be freely moving. Put your feet into the massager, and now you’re ready to enjoy a foot massage.

When you’re ready to switch to a calf massage, rotate the ottoman until it “clicks” into place. Then, insert your legs into the massager, and now you’re ready for a calf massage. The calf and foot massager on the Human Touch ZeroG 2.0 massage chair is a creative solution to an otherwise limited feature. It will save you some serious cash — if you’re OK with not having a calf and foot massage at the same time.

Unique Features of the Human Touch ZeroG 4.0 Immersion Seating Massage Chair


Enclosed Calf and Foot Massager

Whereas the calf and foot massager on the ZeroG 2.0 is open-toed, on the Human Touch ZeroG 4.0 massage chair and ZeroG 5.0, it’s enclosed-toed. OK, so enclosed-toed is not an official technical term, but you know what we mean: the ottomans have both a calf and foot massage portion.

Now instead of toggling between massage types, with the ZeroG 4.0 and ZeroG 5.0, you can enjoy a calf and foot massage simultaneously.

Both massage chairs feature mechanical foot rollers in the foot portion of the ottoman which have three speed settings that you can adjust on the remote. Although, the ZeroG 5.0 immersion massage chair features additional speed settings which we’ll explain later in the article.

Easy Sleeves

The outside of the calf and foot massager ottomans on the ZeroG 4.0 and ZeroG 5.0 are upholstered with SofHyde. However, the insides are lined with Human Touch’s Easy Sleeves — removable and machine-washable fabric liners. The Easy Sleeves make cleaning inside of the ottoman a snap. Like the softening-massage pads, if misplaced, can be purchased from Human Touch for a fee.

3D Massage Technology


One of the biggest differences between the Human Touch ZeroG 2.0 massage chair and the Human Touch ZeroG 4.0 and 5.0 massage chairs is the massage technology. Both the Human Touch ZeroG 4.0 and the Human Touch ZeroG 5.0 feature 3D massage rollers.

So what is 3D massage?

The “3” in 3D denotes the number of dimensions, and the “D” represents, you guessed it, dimensions. Together, 3D tells us that there are three dimensions of movement. On a massage chair, that means the massage rollers move in three ways. For 3D massage, the three dimensions are usually up and down (vertically), side to side (horizontally), and pressure (penetrating inward).

So unlike the Human Touch ZeroG 2.0 massage chair which is 2D, the rollers on the ZeroG 4.0 massage chair and the ZeroG 5.0 massage chair apply inward pressure, increasing the intensity and depth of massage.

The intensity settings on the ZeroG 4.0 and ZeroG 5.0 can be adjusted by three levels and are divided into two independent areas: shoulders and lower back. Since the areas are separate, you can adjust the intensity for each zone individually. So you can have the gentlest intensity on the shoulders and the strongest on the low back — simultaneously.

One-Step Zero Gravity

Another distinguishing feature on the ZeroG 4.0 and ZeroG 5.0 massage chairs is the one-step Zero Gravity function.

On the remote, a “Go to Zero” button lets you easily and automatically recline the massage chair into Zero Gravity. As you press and hold the button, the backrest reclines and footrest raises until your body is in a neutral posture position.

BodyMap PRO


A distinctly Human Touch feature that not only sets the ZeroG 4.0 and ZeroG 5.0 apart from the ZeroG 2.0 but massage chairs in general, is BodyMap PRO.

BodyMap PRO is a group of automated programs that target specific areas of the body. It’s not a preset massage program. And it’s not a manual mode function. Instead, it combines the benefits of both. These benefits are the ease of a preset and the targeted treatment of manual mode — with the help of a body image map.

Located on the remote, “simply press [on the body map] where you want to feel better,” explains Human Touch. The BodyMap PRO displays a figure of a body divided into seven regions. When you select a region, a seven-minute massage session focusing on the area begins.

Let’s take a look at the seven BodyMap PRO regions...

1. Treats the neck.
2. Treats between and around your shoulders.
3. Treats under your shoulder blades.
4. Treats the middle of your back.
5. Treats from your lower back out to your sides.
6. Treats along the spine on the lower back.
7. Treats the glutes with a targeted air point massage.*

*You can combine these air point massage for the glutes (region seven) with any of the other six neck or back zones.

In this Human Touch ZeroG 4.0 review, we know that BodyMap PRO makes it easy to get immediate treatment where you need it most without having to press through a series of manual mode options.

Turbo Point Seat Air Massage


The air point massage is possible thanks to two rows of rapidly inflating and deflating air cells (airbags) and a layer of Visco foam located in the seat of the chair. Together, the air cells and foam massage the buttocks and thighs helping to increase circulation and relieve pain.

You can enjoy a seat air massage two ways: with BodyMap PRO or by selecting the “Seat” massage on the side of the remote. You can add the “Seat” massage to any stationary massage program, however, the BodyMap PRO massage only works with the other BodyMap regions.

Foot Vibration Massage

If you really want to enhance your massage experience, click the “Foot Vibration” button to turn on the foot vibration massage. The vibration massage on the ZeroG 4.0 and ZeroG 5.0 uses a high-frequency massage plate that stimulates the circulation of the legs and feet. This feature adds another dimension to the already comprehensive calf and foot massage.

Unique Features of the Human Touch ZeroG 5.0 Immersion Seating Massage Chair

Now that we’ve covered the unique features of the Human Touch ZeroG 4.0 massage chair, it’s time to take a look at the final chair on our list: the Human Touch ZeroG 5.0 massage chair.

3D FlexGlide Massage Technology


Both the ZeroG 4.0 and ZeroG 5.0 have 3D massage technology, but only the 5.0 features 3D FlexGlide technology.

If you’ve spent much time researching, you may have seen FlexGlide technology described as “the feeling of having a warm oil massage.” And if you’re like us, you’re probably thinking, what does that mean? It’s true some of the not-so-helpful marketing lingoes can get confusing, so let us explain

FlexGlide is a fancy way to describe how the massage head rollers move. With FlexGlide technology, the dual head rollers move in an orbital pattern that glides across the back.

The movement is free of friction and resistance, giving the sense of “a warm oil massage,” which is to say a “resistance-free” massage.

Additional Manual Mode Options

Although the ZeroG 5.0 has almost same manual mode options as the ZeroG 4.0, it does have one additional feature: independent calf and foot massage intensity settings. Rather than only having three settings which adjust the intensity of both the calf and foot massage, the ZeroG 5.0 massage chair has six: three for calf and three for foot.

Larger Size

Last but not least, the ZeroG 5.0 massage chair is slightly wider and taller than both the ZeroG 2.0 and the ZeroG 4.0 massage chairs. Although still compact, the larger build of the ZeroG 5.0 massage chair makes it a great option for taller users.

Warm Air Technology


A significant difference between the ZeroG 4.0 and ZeroG 5.0 is warm air technology, also known as heat therapy. Although a standard massage chair feature, heat therapy on the ZeroG 5.0 is an entirely different experience.

Rather than using heating pads, the heat therapy on the ZeroG 5.0 uses warm air that circulates through the backrest delivering warmth to the lower back. Tiny holes in the upholstery on the backrest are what allow the warm air to pass through the fabric.

Since the heat passes through the fabric and doesn’t heat it, Human Touch claims that warm air technology protects the material from damage and degeneration over time. Warm air technology also has a distinctly massage-friendly benefit: it relaxes the muscles, helping the rollers provide a deeper massage.

What’s Missing on the Human Touch ZeroG Massage Chairs

All three of the Human Touch ZeroG massage chairs have a good variety of features, but there are a few you won’t find on them, including:

× Arm and Hand Massagers

Human Touch strives to design chairs that look as much like luxury recliners as they do massage chairs, arm massagers — which can be big and bulky. That is why these features are absent on many Human Touch models, including all three ZeroG massage chairs.

Although not entirely absent from Human Touch’s lineup, the most affordable chairs with arm massage are the AcuTouch 6.0 and Bali massage chairs which cost around $5000 — $2000 more than the ZeroG 4.0 and ZeroG 5.0.

× Body Scan and Shoulder Height Settings

All three ZeroG massage chairs lack Human Touch’s body scanning software — AcuPoint Detection — and their shoulder height settings.

The body scanning feature enables the chair to detect your height and fit before adjusting the massage movements to give you a custom-fit massage. It also allows you to manually adjust your shoulder setting, which is the height at which the rollers hit.

What About Other Massage Chairs?

If your budget is upwards of $3000, you have many massage chair options to choose from. So how do you know you’re making the right choice? That’s a tough question to answer because each person’s needs are different. But let’s take a look at what features are available on a similarly priced massage chair: the Osaki OS 4000T.

The OS 4000 massage chair is one of the most popular models Osaki offers thanks to an attractive combination of price and features. At under $3000, here’s a glance at some of the features on the Osaki OS 4000:

  • Computer body scan that detects your height
  • Eight preset massage programs
  • Full-sized remote LCD screen and secondary wireless remote
  • Two stages of Zero Gravity
  • Arm and hand air massagers
  • Shoulder air massagers with adjustable widths
  • Hip air massage
  • Heat therapy on lower back
  • Five levels of speed and intensity adjustment
  • Seat vibration massage

Although knowing what features your money can buy is ideal for building a frame of reference, comparing features isn’t always the best way to choose the “right” massage chair. Pay attention to details like where the massage chair is manufactured and where the customer service is based. Also, the warranty options, the weight of the chair, the aesthetics, the upholstery, and, of course, user reviews.

ZeroG 2.0 vs. ZeroG 4.0 vs. ZeroG 5.0: Which Massage Chair is Best?


These massage chairs have a lot in common: they look similar, have the same style and number of massage techniques, and the same number of massage programs. But they’re also very different. Those differences are especially evident between the ZeroG 2.0 and its successors the 4.0 and 5.0.

On the Human Touch ZeroG 2.0 massage chair, you won’t find an enclosed calf and foot massager or additional features like BodyMAP PRO, 3D massage technology or warm air technology. That said, the ZeroG 2.0 is significantly less expensive than the 4.0 and 5.0 — $2000 less.

If the additional features on the ZeroG 4.0 and ZeroG 5.0 don’t seem worth the money, save yourself a few thousand dollars and go with the ZeroG 2.0 massage chair.

Do you want more control over your massage quality and intensity, enjoy simultaneous calf and foot massage, and like the targeted treatments of BodyMap PRO? Then it’s a choice between the ZeroG 4.0 and ZeroG 5.0.

Choosing between these two massage chairs is like choosing between two slices of pepperoni pizza that are the same price but one has more pepperoni. We’d go with the more-pepperoni-for-the-money slice. That is unless you don’t like pepperoni, or in the case of the ZeroG 5.0, the warm air technology, added foot massage intensity control, and larger size. The point is that both the ZeroG 4.0 and ZeroG 5.0 massage chairs are solid options for the price, so choosing one over the other comes down to personal preference.

Human Touch ZeroG 5.0 Review Final Thoughts

The combination of patented technology, luxurious-looking design, and budget-friendly price point make the ZeroG massage chairs compelling buys. Even so, if additional features like warm air technology and 3D massage aren’t on your list of massage must-haves, you can save a few thousand dollars by going with the ZeroG 2.0 massage chair.

But if you want more control over your massage, more features to enhance your massage experience, and have a larger budget, the ZeroG 4.0 and ZeroG 5.0 massage chairs won’t disappoint. We hope our Human Touch ZeroG 5.0 review made your decision process a little easier.
