THE PROBLEM EVERY ENGINEER FACES
Here's something they don't teach you in audio school: the wrong chair will end your career faster than bad monitoring.
Almost 40 years ago, ergonomic researchers made a discovery that should have changed everything. When you move from standing to sitting, the load on your intervertebral discs increases by over 40%. And when you lean forward to work—the position every engineer, lighting designer, and FOH tech spends hours in daily—traditional office chairs become torture devices.
"As you raise your thigh to sit, forcing your knee to a 90-degree angle, your pelvis rotates backward and tucks your tailbone under. This positioning stacks your intervertebral discs in a way that creates massive pressure on the discs, the nerves radiating from your spinal cord, and the connective tissues in your lower back. This isn't discomfort—it's cumulative trauma disorder. The kind of chronic back pain that ends careers."
— Ergonomic Research, 1985
Standard office chairs are designed for people who lean back and rest. You don't rest. You work. You lean forward over consoles. You reach for faders. You're locked in position for hours chasing a mix, programming a light show, or dialing in a broadcast feed. Every minute in the wrong chair compounds the damage.
We built Stealth Chairs because there wasn't a better way to sit—until now.
WHO WE ARE
ErgoLab has been an industry leader in ergonomically correct chair design and manufacturing for nearly four decades. We're not a furniture company that stumbled into pro audio—we're ergonomic specialists who understand your unique demands.
People are different. Not profound, but most chair manufacturers overlook this. At ErgoLab, we've embraced it by designing each chair to not only fit your body, but to specifically perform in your demanding work environment.
WHY WE EXIST
Sit in a Stealth Chair for any length of time and you'll realize it's like nothing you've sat in before. That's because we design for a specific combination of physical attributes and professional responsibilities.
Our exclusive designs provide unparalleled support that promotes proper posture during both resting and working activities, minimizes fatigue, reduces chronic back/neck/arm pain, and increases circulation. All of which help you perform at your best.
THE SCIENCE: PATENTED ZENWAVE™ TECHNOLOGY
Using patented technology, we designed a chair that allows you to maintain the natural lordosis curve in your lower back while leaning forward—something impossible with traditional chairs.
The secret? A seat shell that pivots as you lean forward, combined with a convex-shaped, specially tensioned mesh surface. This eliminates harmful loading of the intervertebral discs in both active working and resting positions.
This technology also equalizes pressure from the seat surface, eliminating uncomfortable pressure points under your thighs, tailbone, and hips as you lean forward. You'll feel like you're floating.
THE FLOATING BACKREST THAT WORKS WITH YOU
While most backrests are designed with a concave shape (which creates pressure points), our backrest is shaped to exactly match the convex lumbar curve of your lower back. Combined with a spring-loaded floating mechanism, the backrest literally moves with you as you lean forward and backward.
Here's what makes this revolutionary:
The floating motion constantly rolls up and down your back, actually massaging the muscles to increase blood flow and hydration of the intervertebral discs. This massaging action keeps your back muscles refreshed even during marathon 16-hour sessions. Your back gets better as the day goes on, not worse.
Unlike any other chair in the world, Stealth models can be used in traditional upright seated position OR in a forward-tilted declining position. For the first time in human existence, there's a better, healthier way to sit.
TRUSTED BY THE INDUSTRY'S BEST
From major recording studios to world tours • From broadcast facilities to festival FOH positions
Stealth Chairs are the choice of professionals who refuse to compromise
WHERE STEALTH CHAIRS WORK
A Stealth Pro Chair at front-of-house
Tracking, mixing, mastering—anywhere engineers spend hours leaned forward over consoles
FOH, monitor world, lighting control—non-reflective midnight black won't catch stage lights
Side stage, control rooms, anywhere you need height adjustment and mobility
Video engineering, post-production, control rooms—precision work requires precision seating
Houses of worship, theaters, arenas—anywhere professional audio happens
Studio sessions, rehearsals, live performance—Performer Series stools for instruments
BUILT TO LAST, DESIGNED TO ENDURE
We don't cut corners. High-strength fiber-reinforced frames—the same material used in aerospace and military applications. Precision-tensioned mesh engineered to maintain its properties through years of daily use. Class 4 gas cylinders. Powder-coated bases. Every component selected for durability, not price.
That's why we back every Stealth Chair with a 5-year comprehensive warranty—one of the longest in the entire furniture industry. Most companies offer 1-2 years. We offer five. Because when you're engineering records that will be heard for decades, your chair should be built to the same standard.
WE ACTUALLY SELL REPLACEMENT PARTS
These chairs last so long, we actually sell replacement parts. Suspension bushings, cylinders, casters, levers, backrests—everything is serviceable and available. While other manufacturers expect you to throw away a $750+ chair when one component fails, we designed Stealth Chairs to be maintained and repaired.
This isn't planned obsolescence. This is engineered longevity.
Buy once, maintain forever.
Available replacement parts include: extra-tall cylinders for lighting positions • TourMax heavy-duty casters for tour life • suspension bushings for wear and tear • paddle arms for added support • executive backrests for reclining • beverage holders • chair glides for stationary positions. Everything you need to keep your chair performing like new.
CUSTOMER SERVICE THAT ACTUALLY CARES
Unlike companies that disappear after the sale, we refurbish our own chairs in-house and provide industry-leading customer support. Got a question at 11 PM before a session? Need a replacement part shipped overnight? Want to upgrade your existing chair?
We're here for you—not just at purchase, but for the life of your chair. When you invest in a Stealth Chair, you're not just buying furniture—you're joining a community of professionals who demand excellence and get real support when they need it.

DETAILS
STEALTH CHAIR TECHNOLOGY
Patented engineering that actually improves your back health while you work
WHY TRADITIONAL CHAIRS DESTROY YOUR BACK
The revolutionary Stealth™ chair was designed for professional music, lighting, and video engineers who sit at different heights working at consoles, desks, and control surfaces. Specifically produced in non-reflecting Midnight Black, the Stealth is perfect for FOH or side-stage locations—it won't reflect spotlights or light sources, keeping you invisible while you work your magic.
SEE THE DIFFERENCE IN ACTION

CRITICAL SPECS & WHY THEY MATTER
Why it matters: Stage lights, camera rigs, and console monitors won't catch reflections from your chair. Critical for FOH positions, broadcast facilities, and side-stage work where even small reflections can distract performers or create visual issues on camera. This isn't about aesthetics—it's about professional invisibility.
Why it matters: The same material used in military and aerospace applications. This isn't cheap plastic—it's engineered composite that flexes precisely to distribute weight while supporting up to 350 lbs. The frame's unique flexing properties work with the mesh tensioning to eliminate pressure points. This technology is what makes the ZenWave™ motion possible.
Why it matters: Not all mesh is created equal. The Stealth uses different tension zones across the seat—tighter where you need support, more flexible where you need give. This precise engineering disperses your weight optimally regardless of your body position. Combined with the fiber-reinforced frame, this creates the "floating" sensation that eliminates pressure points completely.
Why it matters: When you lean forward to work, traditional chairs force your pelvis to rotate backward—stacking your spine unnaturally and crushing your discs. The Active Tilt seat pivots forward with you, maintaining proper pelvic position and natural spine curvature. This single feature prevents the 40%+ disc pressure increase that standard chairs create. You can lean into marathon sessions without cumulative damage.
PATENTED ZENWAVE™ MOTION TECHNOLOGY
The patented ZenWave™ motion provides unbinding, stress-free support as you lean forward naturally, protecting your lower back from further injury. The scientifically designed backrest moves with you to massage the lumbar area of your spine, increasing blood flow and nutrients to lower back muscles and intervertebral discs.
The patented ZenWave™ motion technology allows you to float forward and backward without harmful pressure. Your body's natural movements are supported, not restricted.
The Active Tilt™ seat plate pivots smoothly forward and backward to promote proper body alignment, maintaining your natural lordosis curve in all positions.
The "Free-Float" backrest stays with you as you lean forward, giving continuous support. Unlike static backrests that abandon you when you work.
Customize your seat and backrest position with three lever adjustments. Height, tilt angle, and backrest tension—dial in your perfect working position.
Cool breathable mesh prevents perspiration buildup and keeps your clothes looking fresh. No more sweat-soaked shirts during marathon sessions.
The floating backrest actively massages your lumbar region with every movement, increasing blood flow and nutrient delivery to discs and muscles.
PRESSURE DISTRIBUTION: TRADITIONAL VS STEALTH
Traditional Office Chair
Stealth Chair with ZenWave™
These aren't theoretical numbers. Independent ergonomic studies show that the Stealth Chair reduces pressure points by 70% compared to traditional office chairs, while providing 80% more continuous lumbar support during forward-leaning work positions. The result? You can work longer, feel better, and protect your career from chronic pain.
PERFORMANCE OVER TIME: 16-HOUR SESSION
- Consistent energy through 16+ hour sessions
- No back pain during or after work
- Better focus in final hours of project
- Reduced fatigue-related mixing errors
- Can work multiple days without recovery time
- Significant fatigue after 6-8 hours
- Lower back pain starting at hour 4
- Mental fog in final hours
- Increased mistakes and revision needs
- Require full day recovery between sessions
The difference compounds over years. Engineers using Stealth Chairs report 60% less chronic back pain and 70% fewer days lost to injury compared to colleagues using traditional office chairs. Your chair is either extending your career or ending it.
THE CONVEX-SHAPED FLOATING BACKREST
Most backrests are concave—curved inward. This creates pressure points and forces unnatural posture. The Stealth backrest is convex—shaped to exactly match the natural outward curve of your lumbar spine.
Combined with the spring-loaded floating mechanism, the backrest "floats" with your movements as you lean forward and backward. This constant rolling motion actually massages the muscles in your lower back, increasing blood flow and hydrating your intervertebral discs.
The result? Your back muscles stay refreshed even during extended work sessions. Unlike any other chair in the world, Stealth models support you in traditional upright seated position OR forward-tilted declining position. For the first time in human existence, there's a better, healthier way to sit.
The convex shape matches your spine's natural curve, eliminating pressure points and providing continuous massage with every movement
