This week, two major office furniture corporations released full-back gaming chairs. HNI (the 4th largest) runs Respawn as its gaming chair division. The Respawn Flexx Faze Clan Edition celebrates an elite esports partnership. Herman Miller also jumps into the mix with a drastic ergonomic detour. Its Vantum Gaming Chair breaks Herman Miller’s own principles to support what modern gamers demand: support for good postures and relaxed ones!
Herman Miller Vantum (left) vs Respawn Flexx gaming chairs.
The Herman Miller Vantum and Respawn Flexx are both full-back gaming chairs with adjustable headrests. For Herman Miller, both aspects are a radical departure.
Since its Aeron chair launched in 1994, the company has built its ergonomic legacy on two principles. First, mid-back chairs with limited recline ranges provide the best back support.
Using a headrest rotates the upper spine rearward.
Second, “leaning your head back on a headrest while in an upright position would be improper posture.” Science supports this. A rearward neck tilt rounds the upper back and flattens the lumbar curve(1).
Herman Miller has declared its legacy mid-back chairs too restrictive for modern gamers.
Despite this, the Vantum chair embraces the full-back + headrest concept. Why such a drastic about-face? The Handbook of Human Factors and Ergonomics documents institutional workplace design standards. Its (2021) 5th edition suggests a drastic shift in priorities.
Today’s desk workers combine desktop and mobile computing over longer sedentary periods. Beyond good back support, they need ergonomic neck support + sedentary computing solutions (more movement).
Herman Miller now touts active, dynamic full-back postures over its former strict mid-back support style.
This reflects Herman Miller’s justification for the Vantum chair(2). “Gamers require versatility. A strong active posture is critical for gameplay, but having an equally supported, reclined position for moments of relaxation is key.”
Vantum Gaming Chair Vs Respawn Flexx
The new Flexx Faze Clan Gaming Chair costs $204.84 on Amazon. Standard-style Flexx chairs (with black, red, blue, or brown trim) cost $248.99 on Amazon. On Respawnproducts.com, the Faze Edition costs $529; others cost $399.
The Flexx is cheaper up-front; the Vantum provides nicer aesthetics and better long-term value.
Meanwhile, the (a much better long-term value). At a glance, the Vantum also stands out with the refined, elegant aesthetics that Herman Miller is famous for.
All chairs that qualify as ‘ergonomic’ come with three core adjustable features.
Adjustable lumbar support keeps the spine aligned while sitting. Adjustable arms provide extra bracing to hold the spine upright. A reclining backrest enables healthy seated movement.
A 0° cervical tilt + 25-45° lumbar curve produces a picture-perfect neutral sitting posture.
Combined, these help users maintain neutral sitting postures. These align the spine as if in a healthy standing position. As a result, users can sit for long periods without muscle strain.
New Factors: the prevalence of mobile computing has made good neck posture a consideration when assessing a chair’s merits. Beyond this, modern gamers don’t need to sit straight all the time — support for relaxed postures is crucial.
Modern Gaming Chair Support Factors
As always, an ergonomic computing chair needs adjustable lumbar and arms to promote neutral postures. It also needs a reclining backrest to help the seated body move.
Cubicle-style = strict postures; WFH and gaming style = strict + relaxed.
By modern standards, a good chair should also support good neck posture. As well, it should allow for relaxed positions. Despite the loss of postural integrity, these promote more movement while supporting periods of necessary downtime.
Both chairs meet the ergonomic basics with adjustable lumbar support, adjustable arms, and a reclining backrest. Each also has seat sliding functionality; Herman Miller hasn’t disclosed the Vantum’s depth-adjustment range.
Neither chair comes with a recommended size rating. Based on the listed dimensions, each appears designed for average sizes roughly between 5’8″ to 6’2″

Lumbar Support
Human spines are not all the same size. Adult men average a 30″ spinal length; the average for women is 24″. Regarding lumbar support, this comprehensive peer review states that lumbar support should hit 4 cm deep into the lower back curve.
A 25-45° lower back curve produces a picture-perfect neutral sitting posture.
The average man should adjust his lumbar around 7.5″ above the seat; the average woman should adjust the height to around 5.5″ above the seat. Per the peer review, “If lumbar support causes discomfort, it means it is set too high, too low, or too deep.”
The best lumbar supports need adjustability to support different spine sizes.
Based on these facts, the Flexx Chair does what’s needed. In contrast, the Vantum chair’s dual-pad system blends flashy looks with limited functionality!
Respawn Flexx Lumbar
The Flexx has an integrated lumbar support system with a set depth and adjustable height. Usage is foolproof. Reach behind the backrest, grasp the adjustment levers, and adjust up or down as needed.
Our ranking of the best lumbar support systems lists integrated ones with height x depth adjustability first. These let you adjust your lumbar support to perfection. However, many beginners find these settings too complex.
As a result, we rank height-adjustable integrated lumbar systems as the second-best option. Although not as precise, they’re much easier to use!
The Vantum chair ports over the super-fancy Posturefit lumbar support from the Herman Miller Aeron. At a glance, this spectacular-looking device implies next-level back support. In practice, it lacks height adjustability.
Despite its flashy looks, Posturefit’s missing height-adjustability makes it unusable for many.
Posturefit is the world’s only lumbar system with two pads. The top one supports the lumbar curve; the bottom one adds pressure to the sacral spine. But without height-adjustability, it’s likely that they won’t hit both points exactly as you want them to.
The Aeron comes with a choice of height-adjustable lumbar (recommended) or depth-adjustable PostureFit.
For these reasons, ChairsFX highly recommends that Aeron buyers choose the sliding lumbar support option instead. Although not as flashy as the Posturefit, its height-adjustability guarantees a fit that’s tailored to your size.
The Vantum’s lumbar system has a single depth-adjustment setting.
On the Vantum chair, the Posturefit controller knob has a single setting. Turn it forward to push the pads deeper into your spine. Turn rearward and the pads will snap back by a few millimeters.
Head-to-head
The Flexx chair’s integrated height-adjustable lumbar works well. The Vantum’s Aeron-style Posturefit Lumbar looks spectacular but lacks height adjustability — with an imperfect fit, the Aeron version isn’t comfortable!
Recline Functionality
Each chair deploys a different recline strategy. Summary:
Flexx Chair Recline
The Flexx Series has a basic recline of 90-115°. This 25° range isn’t deep enough for napping — but deep enough to allow plenty of movement. It also comes with built-in synchronous tilt functionality.
The Flexx chair has a 90-115° recline range with built-in synchro-tilt functionality.
As you lean back, the seat tilts upward. Respawn hasn’t specified the angle, although most systems tilt at a 2:1 ratio. Given the Flexx chair’s 25° recline range, the tilt range is most likely 12.5°
Vantum Chair Recline
The Vantum chair comes with a tilt limiter + tilt tension, but Herman Miller hasn’t released further details. Visually, it resembles the Embody Gaming Chair’s functionality. Its tilt-limiter has a recline range of 94-120°.
Embody vs Vantum recline: Vantum encourages relaxed postures that sacrifice good neck posture.
You can’t lock the backrest at angles; instead, you can limit the tilt range to 3 different depths. The big difference between the Embody and Vantum is the presence of a headrest. At a glance, the neck support provided by the Vantum looks gruesome in comparison.
However, as with all full-back gaming chairs, good back support requires tucking your hips deep into the seat. Then, strict and relaxed postures in a Vantum chair look great.
All full-back ergonomic chairs require tucked hips for optimal back support.
Usually, hips sliding forward will round the upper spine. To address that, the Vantum also has a (non-adjustable) upper back support pad.
The Vantum adopts the Embody’s upper back support concept with a thoracic (upper) spine support pad.
This resembles the thoracic support concept of the $1700 Embody chair. Support for the upper back curve should (in theory) prevent slouching in the upper back area.
Head-to-head
The Flex chair’s 90-115° recline + sync-tilting seat makes it easy to move while sitting. The Vantum chair provides similar recline functionality (minus sync-tilt) with added thoracic (upper spine) support. Both do a similar job: the Vantum does it with more pizzazz.
Headrest Functionality
Like most on the market, both the Flexx and Vantum headrests let you adjust the height and angles only. This seems mediocre — it’s the same functionality as cheap $200 chair headrests!
The Vantum chair’s headrest delivers the same adjustability as $200 office chair headrests.
However, the lack of depth adjustability exists for a reason. Herman Miller has long insisted that “leaning your head back on a headrest while in an upright position would be improper posture.”
The headrest does not touch the neck when sitting in upright positions.
To that end, Herman Miller notes in its press release(2): the headrest does not touch the neck while sitting upright. Only when the user reclines will the headrest come into play.
Herman Miller deserves credit here. At a glance, the Vantum appears to throw its old concepts off a cliff. In reality, a carefully-designed headrest depth plus a thoracic support pad helps the Vantum to retain Herman Miller’s core principles.
Gaming Chairs: So Hot Right Now!
Herman Miller spearheads MillerKnoll, the largest conglomerate of B2B design houses the world has ever seen. Respawn is a subdivision of HNI, the 4th-largest office furniture corporation. Combined, these two behemoths generated $5.7 billion in revenue last year!
The top six office furniture companies of 2022 (based on total 20201 earnings).
In contrast, top full-back gaming chair companies earn around $300 million in revenue per year. For major office chair corporations, this is chump change. So why the embrace of full-back gaming chairs?
Gaming chairs are primed to become the dominant seating choice for modern WFH gamers.
According to Herman Miller’s Vantum press release(2), modern gamers prefer varied support for both upright and relaxed computing postures.
L-R: Herman Miller Aeron, Embody, and Vantum ergonomic chairs.
As cubicle-era boomers give way to fresh blood, all signs point to full-back gaming chairs becoming the go-to seating option for the WFH crowd.
Full-Back > Mid-Back Ergonomic Chairs
What’s the difference between a mid-back ergonomic office chair and a full-back gaming chair? Herman Miller’s Vantum press release gives us a fresh definition from the very top of the ergonomic hierarchy.
Herman Miller now touts active, dynamic full-back postures over its former strict mid-back support style.
First, both support healthy neutral postures for long periods of computing. But today’s computer users don’t sit stiffly all day like the office cubicle jockeys of yesteryear.
Ergonomic seating styles for the cubicle and work-from-home eras.
“A strong active posture is critical for gameplay, but having an equally supported, reclined position for moments of relaxation is key.” This concept isn’t new.
Full-back gaming chairs provide versatile all-day sitting support.
ChairsFX clarified this in our Gaming Vs Ergonomic Office Chairs explainer article. Mid-back office chairs come with limited recline ranges that force users to sit upright at all times.
Which one looks more comfortable — from YOUR perspective?
In contrast, full-back gaming chairs provide deep recline functionality that supports both strict and relaxed postures. Both styles have merits and drawbacks. Learn more:
Since the 2020 lockdowns, technostress burnout has been running wild in corporate America. In 2021, a ‘Great Resignation’ saw 47 million Americans quit their jobs. In 2022, among those who remained, over 50% have mentally checked out as ‘quiet quitters’.
Corporate burnout has turned half of the U.S. workforce into quiet quitters.
Meanwhile, Bloomberg reports(3) that ‘work from home is sticking’. “The grand migration back to offices after Labor Day that many CEOs and civic leaders envisioned hasn’t materialized.”
Workers are not returning to offices in mass as managers had hoped.
These factors are shedding more light on the benefits of cognitive ergonomics. Ergonomists define comfort as environmental factors which improve physical or psychological wellness(4). Psychological wellness comes from serving unique human needs.
Both chairs are good for your back; the Vantum (right) is more psychologically comfortable.
Herman Miller once did a study(5) on this to justify its exquisite chair aesthetics. It found that people who personalize and prettify their workspaces enjoy a greater sense of well-being and comfort.
The Vantum and Flexx chairs both come with aesthetics appropriate for their price tags.
With this in mind, it becomes evident why the Vantum costs twice the price of a Flexx chair. Although both do a similar ergonomic job, the Vantum is sleeker and sexier. Is a more refined style worth paying a premium for? That depends on your aesthetic preferences.
The Vantum chair project “started with the challenge of deconstructing what the essence of a gaming chair truly is.”(2) In the gaming chair industry, the Secretlab Titan ranks well ahead of generic gaming chairs by a massive margin.
GTRacing Pro Series vs Secretlab Titan 2022 Series (Charizard edition).
That makes the Secretlab Titan 2022 Series the (current) gaming chair benchmark. Here’s a quick look at how the industry-leading Titan compares to the corporate newcomers:
Ergonomics
The three fundamental ergonomic features are adjustable lumbar support & arms + a reclining backrest. The Titan beats the others among all three.
Highlight Titan Evo 2022 Series features.
First, its integrated lumbar is height and depth-adjustable. Second, its deeper recline range provides more versatility than limited ones. Third, its 4D arms are more adjustable than either the Flexx or Vantam. Core component comparison:
The Titan blows away all competing gaming chairs with a growing collection of over 45+ styles. Chairs come upholstered in Softweave fabric and leatherette variations that cover the entire color spectrum.
Secretlab Titan 2022 Series chairs come in 45+ styles.
In the mix are official chairs for esports teams, TV shows, video games, and esports tournaments. For instance, a few days after the Vantum chair release, Secretlab dropped a pair of official Naruto gaming chairs.
Naruto and Akatsuki Softweave Titan gaming chairs are now available.
Many of these designs appeal to existing Titan owners as collector’s items. As a result, many Titan owners become loyal fans who own multiple Titan chairs.
Bottom line: Herman Miller’s comfort study(5) found that people who personalize and prettify their workspaces enjoy enhanced well-being and comfort. On that front, the Titan beats the Flexx and Vantum by a large margin!
Neck Support
The Titan’s memory foam magnetic headrest beats the competition by a large margin. Here’s a quick comparison of headrest types:
Hard Office-Style Headrests
In upright positions, good back posture should naturally balance the head above the shoulders. The problem is that in this mobile computing era, forward neck postures are endemic.
Office-style headrests don’t support the neck in upright positions.
Even if you’re ‘supposed’ to balance your head above the shoulders, there’s no way to gauge that when using hard, office-style headrests.
Hard headrests don’t provide ANY support to maintain a straight neck while sitting.
But if you get used to sitting with a forward-tilted neck, your muscle memories will adapt. Then, a forward-tilted neck will start to feel more comfortable than a straight one!
Fundamental Gaming Chair Headrest Problem
A few months ago, while researching text neck syndrome, I decided to test my own seated neck posture. To do so accurately, I removed my headrest and posed for two shots.
My posture test revealed ugly distortion caused by Text Neck Syndrome.
In the first shot, I exert my back muscles to sit as straight as possible. In the second, I tried to relax to reveal my ‘normal’ position. This method was suggested to me by Georgia-based esports therapist Dr. William Duncan.
To diagnose postures, he advised taking side shots in relaxed positions. Those sent to an esports doctor can get you fast help online.

So I did as he advised and sent the pix to Dr. Jordan Tsai. He runs Respawn Therapy in LA, working with many of the world’s top esports teams.
Titan Memory Foam Headrest Posture Therapy
Dr. Tsai also serves on Secretlab’s Ergonomic Advisory Board. He told me that the Secretlab Titan 2022 was specifically designed to support good neck postures. To achieve that, he suggested I set the backrest recline to 100° and focus on sitting straight. It worked!
Achieving perfect neck posture in a Secretlab Titan chair + headrest.
Unlike hard headrests, memory foam versions don’t push the neck forward. Instead, they compress under the user’s body weight. According to Secretlab literate, its 2022 Series headrest has an aggressive downward curve.
Relaxed vs strict neutral sitting postures.
With a 100° recline + good sitting posture, it guides the neck into a clean 0° tilt. Notably, that provides a tactile guide to check your neck. After I adjusted to this style, Dr. Duncan and another famous esports doctor both verified my neck posture as spot-on.
You’ll need to stay disciplined to maintain good posture in a full-back gaming chair.
Three months later, I still sit this way — around 30% of the time. Usually, I prefer relaxed postures with my neck slightly bent. Once that starts making me feel stiff, I do a postural reset: reverting to sharp 100° recline + good sitting posture.
Bottom line: competing headrests are only useful for deep reclined positions. In contrast, the Titan’s headrest also gives you the tools to perform DIY neck posture therapy.
Most pro esports players display terrible posture while gaming — regardless of which chair they use. Even so, many leading esports doctors don’t mess around with gamers’ competitive postures. Instead, they tout stretching, exercises, and healthy lifestyles to balance things out.
Many pro gamers suffer from rounded upper backs caused by leaning forward while competing.
For example, Esports therapist/ Secretlab Ergonomic Board Advisor Dr. Jordan Tsai says you don’t even need a gaming chair! His suggested priorities: “Rest/nutrition/exercises > breaks > good posture > good chair. Developing healthy habits is the most important thing to work on.”
Tfue is one of many mega-successful streamers who incorporate movement and fitness into their routines.
This perspective takes into account the mentally taxing nature of pro gaming. Players rely on elite speed, precision, aim, and hand-eye coordination. The most taxing FPS games can force players to take 400 actions per minute.
With all of that going on, it’s impossible to expect them to sit like robots! In the modern formula, any ergonomic chair that supports ok-ish postures can do the job.
Humans are not robots: good posture + healthy lifestyles = peak performance.
The real work happens away from the computer. Then, so-so gaming posture + rest, exercise, and nutrition = high-performance computing. Learn more:
In late 2021, ChairsFX reported new ergonomic priorities set at the institutional design level. Beyond back support, modern computer users need neck support and more movement. In late 2022, Herman Miller brought these concepts to life with the Vantum Gaming Chair.
The Vantum’s Secretlab-inspired full-back design is designed for the modern gaming and WFH crowd.
This influential megacorporation built its entire legacy on mid-back chairs that force you to sit straight. Bending the knee to the gaming chair concept has massive ramifications.
It’s an endorsement from the top that super-strict sitting all day long is a relic. In its place, pretty good posture, deep reclines, neck support, and psychological comforts take precedence.
Embody vs Vantum: old vs new ergonomic philosophies for gamers.
Beyond the chair, a sit-to-stand desk can provide mobile support and boost movement. Beyond furniture, movement breaks, exercise, and a healthy lifestyle will do wonders.
The Best Gaming Chair For YOUR Needs
Many people hate gaming chairs — but love chairs made by megacorporations. Now, Herman Miller has declared gaming chairs better than office chairs for modern gamers. Besides good posture, modern gamers need to kick back and chillax!
L-R: Vantum vs Faze Clan Flexx gaming chairs.
So which is better: Vantum or Flexx? Both do a similar job at promoting good upright postures. Each also lets you kick back and chillax with a supported neck. As well, each has a corporate aesthetic that differentiates them from racer chairs.
Which style do you prefer? Which fits within your budget? Those answers will determine whether the Vantum or Flexx is better for your particular needs.
