TOURMAX HEAVY-DUTY CASTERS (SET OF 5)

Professional tour-grade mobility • 4" industrial wheels • TPR rubber tread • Cable-crushing capability • Stage-proven durability • Includes 1 locking caster

WHEN STANDARD CASTERS AREN'T ENOUGH

Office casters are brilliant for studios and smooth floors. But when you're rolling over XLR snakes at FOH, navigating festival carpeting, or working elevated stages with cable runs everywhere, you need wheels built for battlefield conditions. TourMax casters are what happens when you engineer casters for the harshest professional environments in the world—tours, venues, stages, and live production.

WHAT TOURMAX CASTERS DELIVER:

Cable-Crushing Capability: 4" diameter rolls over XLR bundles, power cables, and stage rigging without catching or binding

All-Surface Mobility: TPR rubber tread grips carpet, concrete, wood, and uneven stage surfaces that would stop office casters dead

Elevated Working Height: 4" wheels raise your working position ~2 inches vs standard casters—critical for tall console positions

Heavy-Duty Construction: Double ball raceway swivel design supports 350 lbs across the most punishing road and stage environments

Tour-Proven Durability: Zinc-plated finish and TPR rubber formulation withstand load-in/load-out abuse that destroys lesser casters

Locking Security: One locking caster included to prevent unwanted rolling during critical moments—stage setups, FOH positioning, broadcast work

Here's the fundamental difference: office casters are optimized for smooth floors and precision control. TourMax casters are optimized for obstacle clearance and all-terrain mobility. When you're at FOH and there are 47 cables between you and the console, you don't want to stop and navigate around every XLR. You want wheels that crush straight over them without catching, binding, or damaging the cables. That's TourMax.

WHEN YOU ABSOLUTELY NEED TOURMAX INSTEAD OF STANDARD CASTERS:

Tour and live production: FOH positions, monitor world, stage tech—anywhere cables and uneven surfaces are standard operating conditions
Festival and venue work: Temporary stages, carpeted control areas, outdoor surfaces where standard casters would fail
Cable-heavy environments: Recording studios with extensive floor cabling, broadcast facilities, video production control rooms
Carpeted floors: Control rooms, editing suites, corporate facilities where office casters drag instead of roll
Elevated console positions: Standing-height mixing desks, lighting control positions, broadcast consoles where the extra 2" height matters
Mobile rig configurations: Touring consoles, portable control surfaces, temporary setups that move between venues
Uneven surfaces: Stages with cable ramps, venue floors with imperfections, anywhere standard casters catch or jam
Heavy-duty daily use: High-traffic professional environments where casters take constant abuse and office-grade components fail fast

The TourMax casters are genuine OEM components engineered specifically for Stealth and ErgoLab chairs—not generic industrial casters retrofitted to work. The 4" × 1" wheel dimensions, double ball raceway swivel mechanism, and 7/16" × 1-3/8" grip ring stem are precisely matched to your chair's weight distribution and professional use demands. Same quality philosophy, same durability standards, same "built for decades" engineering you expect from Stealth.

THE SIMPLE DECISION:
If you work in a permanent studio or office with smooth floors, Office Casters are your choice. If you're touring, working stages, dealing with cables and varied surfaces, TourMax is essential. Many professionals own both sets and swap based on environment—studio session Monday, festival FOH Friday.

PROFESSIONAL FLEXIBILITY: Many touring professionals maintain both caster configurations. Studio work this week? Install office casters for precision control on hardwood floors. Festival run next week? Swap to TourMax for cable clearance and all-terrain mobility. The chair base accepts both configurations equally—5-minute swap, infinite adaptability. This is how professional equipment should work.

CABLE-CRUSHING CAPABILITY: THE 4" ADVANTAGE

At FOH during a festival, there might be 200+ cables running across the floor—multicore snakes, power distribution, monitor feeds, intercom lines, lighting DMX, video runs. With 2" office casters, you're constantly stopping, lifting the chair, navigating around cable bundles. Every repositioning becomes a multi-step obstacle course.

WHY 4" WHEELS MATTER FOR CABLE ENVIRONMENTS

CLEARANCE HEIGHT

A standard XLR or power cable is approximately 1-1.5" in diameter. 2" office casters have minimal clearance—they catch, hang up, or require lifting the chair to navigate. 4" TourMax casters provide 2.5× the clearance, rolling straight over cable bundles without hesitation.

APPROACH ANGLE

Larger wheels create a shallower approach angle when encountering obstacles. This prevents the "catch and jam" problem smaller wheels experience. TourMax casters ride up and over obstacles that would stop office casters completely.

CABLE PROTECTION

The soft TPR rubber tread distributes weight across a larger contact patch. When rolling over cables, this prevents crushing damage or connector strain. You're not just protecting your mobility—you're protecting expensive cabling infrastructure.

REAL-WORLD IMPACT: At a typical FOH position during a festival, an engineer with office casters might reposition 20-30 times during a show—checking sight lines, referencing artist positions, consulting with stage managers. Every repositioning requires cable navigation. With TourMax casters, those same 20-30 moves happen without thought—just roll where you need to go. That's hundreds of hours saved over a tour or season.

TPR RUBBER TREAD: ALL-SURFACE ENGINEERING

Office casters use ABS plastic tread because it's perfect for smooth, hard floors—non-marking, low friction, silent operation. But put those same ABS wheels on carpet, textured concrete, or outdoor stages and they fail catastrophically. The plastic tread can't grip, can't flex, and provides zero traction. You're not rolling—you're dragging.

TPR RUBBER ADVANTAGES

Multi-surface grip: Rubber compounds flex and conform to surface texture
Obstacle conformance: Soft tread deforms around cables without damage
Vibration dampening: Absorbs shock from stage edges, cable ramps, uneven surfaces
Temperature stability: Performs in outdoor stages (hot summer asphalt to cold winter venues)
Load distribution: Larger contact patch reduces floor pressure points
Durability: Resists chunking, tearing, and wear better than plastic

TESTED SURFACE TYPES

Hardwood/laminate studios – smooth rolling without floor damage
Commercial carpet – low-pile and high-pile control room carpeting
Concrete venues – arena floors, warehouse spaces, outdoor stages
Stage decking – Marley, plywood, composite stage materials
Cable ramps – rolls over cable management systems without catching
Mixed surfaces – transitions between carpet/concrete/wood without hesitation

TPR (THERMOPLASTIC RUBBER) COMPOSITION: TourMax casters use a soft black TPR tread bonded to a polyolefin core for the perfect balance of grip and structural rigidity. The TPR outer layer provides the flexibility and surface conformance needed for all-terrain mobility. The polyolefin core maintains dimensional stability under 350 lb loads. This composite construction is significantly more expensive than simple ABS plastic, but the performance difference is night and day when you leave smooth studio floors.

THE REALITY CHECK:
Try rolling office casters across commercial carpet. Now try TourMax. The difference is immediately obvious—office casters drag and bind, TourMax rolls smoothly. On tour, that difference is the gap between functional mobility and constant frustration.

DOUBLE BALL RACEWAY SWIVEL: HEAVY-DUTY ENGINEERING

The swivel mechanism is where most casters fail under professional use. Cheap casters use a single bearing raceway or simple bushing—it works for light office chairs sitting stationary. But when you're loading 350 lbs onto a chair that's constantly repositioning, pivoting, and absorbing lateral forces on tour, single-bearing designs fail fast. Wobble develops, the swivel binds, directional control degrades.

DOUBLE BALL RACEWAY DESIGN

Two independent ball bearing raceways (upper and lower) share the load and lateral forces. This distributes stress across multiple load paths instead of concentrating force on a single bearing set. The result is dramatically improved durability and zero play under professional loads.

WHAT DOUBLE BALL RACEWAY PROVIDES:

Load distribution: 350 lb capacity shared across upper and lower bearing sets—no single point of failure
Lateral stability: Side forces from rolling over cables or uneven surfaces handled by dual raceways without binding
Zero play: Two bearing sets maintain precise alignment—no wobble even after years of tour abuse
Smooth 360° rotation: Effortless swivel in any direction without catching or resistance
Extended service life: Dual load paths mean each bearing experiences less stress—decades of professional use
Impact resistance: Shock loads from stage edges, cable ramps, or rough handling absorbed across multiple bearing contacts

The plain bore wheel bearing in TourMax casters is hardened steel designed for continuous rotation under load. Combined with the double ball raceway swivel, you get two independent precision bearing systems—one for wheel rotation, one for swivel mechanism. This is industrial-grade construction. When tour managers are rolling chairs over cables, up ramps, across rough stages day after day, the engineering has to be bulletproof. Double ball raceway swivel is how you achieve that.

TOUR-PROVEN: WHERE TOURMAX CASTERS DOMINATE

FOH & MONITOR WORLD:

Front of House and monitor positions feature the most cable-dense environments in live production. Multicore snakes, power distribution, monitor sends, intercom, lighting networks—all running across the floor to reach the console. TourMax casters let you roll freely without constant cable navigation. FOH engineers report that switching from office to TourMax casters is "like getting a new chair"—the mobility difference is that dramatic.

FESTIVAL & MULTI-DAY EVENTS:

Festival sites feature temporary stages, uneven surfaces, and constantly changing cable routing. TourMax casters handle grass patches between concrete slabs, roll over cable ramps without catching, and adapt to surfaces that change hour by hour. Plus the extra 2" height helps when working elevated festival FOH positions or standing consoles. Mobility that adapts to chaos—that's the tour environment.

LIGHTING DESIGN & PROGRAMMING:

Lighting tech positions are surrounded by power cables, DMX networks, and data runs. TourMax casters let you move between console, paperwork, and visual references without fighting cables every move. The larger wheels also handle the cable troughs and raised flooring common in modern venues. When you're programming complex lighting cues, the last thing you need is caster frustration breaking your concentration.

BROADCAST & VIDEO PRODUCTION:

Video control trucks and broadcast facilities feature extensive cable runs and mixed flooring materials. TourMax casters roll smoothly from carpeted control areas to hard floors without adjustment, handle video cables and power distribution without catching, and provide the mobility needed for multi-camera switching and production coordination. The higher working position also helps when working standing broadcast consoles.

RECORDING STUDIOS WITH EXTENSIVE CABLING:

Large format recording studios often feature major cable runs across control room floors—patchbay connections, monitor feeds, outboard gear routing. While office casters work great on clean hardwood, they struggle when you add extensive cabling. TourMax casters provide the cable clearance needed in heavily-wired recording environments. You maintain the professional aesthetic with non-marking wheels while gaining the mobility that cable-heavy studios demand.

CORPORATE AV & INSTALL WORK:

Corporate AV technicians working installations move between carpeted boardrooms, hard floor lobbies, and staging areas throughout the day. TourMax casters handle the surface transitions seamlessly. The durability matters too—install work involves constant repositioning, equipment movement, and environmental variety that wears out office casters quickly. TourMax casters are built for the daily grind of professional AV work.

HOUSE OF WORSHIP & PERMANENT INSTALLS:

Churches and houses of worship often feature carpeted sanctuaries with elevated console positions. TourMax casters provide the all-surface capability needed for carpet while the extra height accommodates standing or elevated FOH platforms. The non-marking tread protects sanctuary flooring. Many worship tech directors prefer TourMax for the versatility—works equally well in carpeted sanctuary or hard floor fellowship hall.

INSTALLATION: GRIP RING STEM SYSTEM

NO TOOLS REQUIRED • 5-MINUTE SWAP

1

Flip chair and remove old casters

Turn the chair upside down on a soft surface (carpet, blanket). Grip each existing caster wheel firmly and pull straight out with steady pressure—the grip ring compression fit releases and the caster slides free. If stubborn, wiggle slightly while pulling.

2

Clean the mounting sockets

Use compressed air or a rag to clean out the five mounting sockets in the chair base. Remove accumulated dust, hair, cable debris, or gunk. Clean sockets ensure proper TourMax caster seating and secure fit.

3

Install TourMax casters

Align each TourMax caster stem (7/16" × 1-3/8" grip ring) with a mounting socket. Push firmly straight down until you feel/hear a solid "snap" as the grip rings engage. Push firmly—the larger TourMax casters need to be fully seated to support 350 lbs safely. No twisting or threading—just straight pressure until it clicks home.

4

Install locking caster & test mobility

Install the one locking caster in the front center position for optimal stability control. Flip the chair upright, test all wheels for smooth rolling over cables and varied surfaces, and engage the lock mechanism to verify secure hold. Total installation time: under 5 minutes.

IMPORTANT: Height Adjustment After TourMax Installation
TourMax casters raise your working height approximately 2 inches vs office casters. If you're switching from 2" to 4" wheels, you may need to adjust your gas cylinder (shorter cylinder) to maintain optimal ergonomic positioning. The details matter when dialing in professional seating.

PRO TIP FOR TOURING PROFESSIONALS: Many tour engineers maintain both caster sets (office + TourMax) and swap based on venue requirements. Studio session with pristine hardwood? Install office casters for floor protection. Festival FOH this weekend? Swap to TourMax for cable clearance and all-terrain capability. 5-minute swap, infinite configuration flexibility. This is how professional equipment should work.

Not generic industrial casters—these are engineered specifically for professional chair applications.

LOCKING CASTER: STAGE SAFETY & POSITION SECURITY

Every TourMax set includes one locking caster that prevents both rolling AND swiveling when engaged. This isn't just convenient—it's critical safety equipment for professional environments where unwanted chair movement could be catastrophic.

CRITICAL LOCKING SCENARIOS:

Stage & platform work: Prevent chair from rolling off elevated FOH platforms, stage edges, or riser positions
Load-in/load-out: Lock during gear setup when you're reaching, lifting, or moving equipment around the chair
Festival positioning: Secure FOH position on uneven ground or sloped festival sites where gravity wants to roll you downhill
Critical mixing moments: Lock for surgical precision work—final mix approval, mastering decisions, client presentations
Cable management work: Lock when routing cables under or around the chair to prevent accidental movement that tangles runs
Standing transitions: Lock before standing up so the chair doesn't roll away (especially important on TourMax with enhanced mobility)
Broadcast "hot" moments: Lock during live broadcasts or recording when any movement could cause problems
Teaching/demonstration: Lock when showing clients, students, or colleagues console operations without chair drift

OPERATION: The locking caster uses a foot-operated brake mechanism that locks both the wheel rotation and swivel movement. Press down with your foot to engage the lock—instant position security. Press again to release for mobility. Install the locking caster in the front center position of the chair base for easiest foot access and maximum leverage. A quick toe tap is all it takes to secure your position or release for movement.

ENGINEERED FOR TOURS, BUILT TO LAST DECADES

Most chair manufacturers don't sell replacement casters because their chairs aren't designed to be serviced. When the casters wear out, they expect you to replace the entire chair. That's planned obsolescence, not professional equipment design.

WE STOCK TOURMAX CASTERS FOR THE SAME REASON WE REFURBISH CHAIRS:
Professional equipment should be built to last decades, easy to maintain, and impossible to make obsolete.

TourMax casters are genuine OEM components featuring the same double ball raceway swivel, TPR rubber tread, and heavy-duty construction as your original equipment. We don't sell cheap replacements or generic alternatives. We sell professional-grade components that match your chair's performance standards and withstand years of tour abuse.

The zinc-plated finish resists corrosion in humid venues, outdoor festivals, and coastal environments. The TPR rubber formulation maintains grip properties through temperature extremes—summer festival heat to winter venue cold. The double ball raceway swivel handles the constant shock loading of tour life—rolling over cables, up ramps, across stage edges, through load-in chaos.

5-YEAR WARRANTY • LIFETIME SUPPORT
A $75 caster replacement every 5-10 years of touring beats a $750+ chair replacement. That's the difference between professional equipment and disposable furniture.

PRO TIPS: TOURMAX MAINTENANCE FOR TOURING LIFE

CLEAN AFTER TOURS

Tour environments are brutal—dust, dirt, cable insulation debris, stage gunk. After major tour runs, flip the chair and clean each caster thoroughly. Use needle-nose pliers to remove hair and thread wrapped around axles. Brush out accumulated debris from the swivel mechanism. 5 minutes of maintenance extends TourMax life by years.

INSPECT BEFORE LOAD-IN

Before major events or tour legs, check TourMax casters for damage. Look for tread separation, cracked wheels, or binding in the swivel mechanism. A failed caster mid-show when you need mobility is unacceptable. Replace damaged casters immediately—don't wait for catastrophic failure during a critical moment.

KEEP SPARES ON TOUR

Professional touring rigs carry spare casters. When you're 500 miles from home and a caster fails, having replacements in the truck prevents equipment downtime. TourMax casters are professional insurance—the cost of spares is nothing compared to lost productivity or gear failure during critical shows.

MATCH CASTERS TO ENVIRONMENT

While TourMax handles most surfaces brilliantly, smooth studio floors don't require heavy-duty tour wheels. Many professionals swap to office casters for permanent studio work, reserving TourMax for tour and live production. Using the right caster for each environment extends the life of both caster sets and optimizes performance.

SEE THE DIFFERENCE IN ACTION

Watch how ZenWave™ motion technology supports your body in real working positions

CRITICAL SPECS & WHY THEY MATTER

MIDNIGHT BLACK NON-REFLECTIVE

Powder-coated finish

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.

HIGH-STRENGTH FIBER-REINFORCED FRAME

Aerospace-grade materials

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.

VARIABLE TENSION MESH SYSTEM

Zone-specific engineering

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.

ACTIVE TILT™ SEAT PLATE

Patented pivot mechanism

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.

LIKE FLOATING ON WATER

The patented ZenWave™ motion technology allows you to float forward and backward without harmful pressure. Your body's natural movements are supported, not restricted.

ALIGN YOUR SPINE

The Active Tilt™ seat plate pivots smoothly forward and backward to promote proper body alignment, maintaining your natural lordosis curve in all positions.

FEEL SUPPORTED

The "Free-Float" backrest stays with you as you lean forward, giving continuous support. Unlike static backrests that abandon you when you work.

EVERYONE IS DIFFERENT

Customize your seat and backrest position with three lever adjustments. Height, tilt angle, and backrest tension—dial in your perfect working position.

BREATHE EASY

Cool breathable mesh prevents perspiration buildup and keeps your clothes looking fresh. No more sweat-soaked shirts during marathon sessions.

MASSAGE & HEALING

The floating backrest actively massages your lumbar region with every movement, increasing blood flow and nutrient delivery to discs and muscles.

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

ABOUT STEALTH

ABOUT STEALTH CHAIRS

Almost 40 years of engineering excellence • Trusted by the world's top studios, tours, and venues

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.

💡 LIGHTING DESIGN

Side stage, control rooms, anywhere you need height adjustment and mobility

📺 BROADCAST FACILITIES

🏟️ PERMANENT INSTALLATIONS

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.

Most orders are completed within 2 weeks' time and shipped within the USA for a total of 3-4 weeks turnaround.

There are times when an order may be placed on backorder and you will be notified by the email and or phone number you provide.

For shipping, we commonly use UPS and have a standard rate of $99 to cover all costs of shipping in the USA. This allows us to ship daily from our facility to you in a timely manner and update your order accordingly.

Working with a dealer

When working with a dealer there may be times when your order is not updated by us.

You will be notified by your dealer on when or where these orders are from Stealth Chairs and if there is a delay the dealer can notify us or you of the expected time window based on the order.

How does the Stealth Chair come and or is it assembled?

Each stool may be dissembled based on the best method of shipping. The stool will be detached from the base and cylinder to make shipping easy.
