Adjustable Footring

STEALTH FOOT RING Essential ergonomic support for elevated seating • Heavy-duty ABS construction • 4-point reinforced structure • Sand-coated finish • Height adjustable • Universal compatibility NOT AN ACCESSORY—A BIOMECHANICAL NECESSITY Here's what most people don't understand about elevated seating: when your feet can't reach the floor, your body compensates in ways that destroy your ergonomics. Your thighs carry your lower leg weight. Pressure builds under your thighs where they contact the seat edge. Blood circulation to your lower legs restricts. Your pelvis tilts backward to relieve thigh pressure, collapsing your lumbar curve and negating every ergonomic benefit your Stealth Chair provides. WHAT THE FOOT RING SOLVES: Thigh Pressure Relief: Supports your feet so your thighs don't carry lower leg weight—eliminates the pressure points that cause numbness and circulation restriction Circulation Maintenance: Proper foot support prevents blood pooling in lower legs and maintains healthy circulation during extended elevated sessions Postural Alignment: Allows proper pelvic positioning and lumbar curve maintenance—preserves the ZenWave™ ergonomic benefits your chair provides Height Adjustability: Tool-free knob adjustment lets you dial in perfect foot support regardless of cylinder height or user leg length Multi-User Flexibility: Quick adjustment accommodates different users with varying leg lengths—perfect for shared workstations or rental applications Professional Durability: Heavy-duty ABS construction with 4-point lateral reinforcement supports users up to 350 lbs—built to the same standards as the chair itself The Foot Ring isn't a comfort upgrade—it's a biomechanical requirement for any elevated seating position. When you're working at standing console height, lighting positions, elevated FOH platforms, or any scenario where the tall cylinder puts your feet 6-12 inches off the floor, the foot ring transforms your chair from "barely functional at this height" to "ergonomically optimal regardless of height." WHEN YOU ABSOLUTELY NEED A FOOT RING: Using tall or X-tall cylinders: Any cylinder configuration where your feet don't naturally reach the floor when seated at working height Lighting tech positions: Elevated control surfaces demand elevated seating—foot ring is mandatory equipment Standing console work: FOH positions at standing height require foot support for proper ergonomics Stage/elevated platform work: When working on risers, stages, or elevated platforms where floor distance varies Multi-height workstations: Facilities with varying console heights need adjustable foot support for each position Shared/rental chairs: Multiple users with different leg lengths need quick foot ring adjustment Extended elevated sessions: Any work lasting 4+ hours at elevated height—circulation and comfort become critical The Stealth Foot Ring is a genuine OEM replacement/upgrade component—not a generic drafting stool ring retrofitted to work. This is engineered specifically for Stealth and ErgoLab chairs, with the same design philosophy: professional-grade construction, thoughtful engineering, and materials that outlast the trends. THE SCIENCE: WHY FOOT SUPPORT MATTERS AT ELEVATED HEIGHTS Understanding the biomechanics reveals why foot support is non-negotiable for elevated seating ELEVATED SEATING: WITH vs WITHOUT FOOT RING WITH FOOT RING WITHOUT FOOT RING Minimal thigh pressure — feet supported, thighs neutral Severe thigh pressure — legs dangle, weight concentrates under thighs Normal circulation — blood flow unrestricted Restricted circulation — thigh pressure impedes blood flow to legs Proper pelvic tilt — lumbar curve maintained, ZenWave™ functions correctly Posterior pelvic tilt — lumbar curve collapses to relieve thigh pressure All-day comfort — can work elevated heights for 8-12+ hours without issues 1-2 hour tolerance — numbness, discomfort, need to stand/stretch frequently No leg fatigue — lower legs supported, muscles relaxed Severe leg fatigue — thigh muscles strain to support hanging lower legs 100% work focus — forget about body, focus on the work Constant distraction — shifting position, adjusting legs, fighting discomfort THE BIOMECHANICS: When your feet dangle, your lower legs' weight (typically 8-12 lbs each, or 16-24 lbs combined) creates downward force that your thighs must resist. This force concentrates at the front edge of the seat, creating a pressure ridge that restricts blood flow through the femoral artery. Within 20-30 minutes, you feel numbness or tingling. Within 60-90 minutes, you're shifting position constantly. The foot ring eliminates this entire cascade by supporting your feet, allowing your legs to rest at natural angles with no thigh pressure. ENGINEERED FOR PROFESSIONAL DURABILITY Cheap drafting stool rings use thin-wall plastic that flexes under weight and cracks after a year of use. The Stealth Foot Ring is engineered to the same standards as the chair it mounts to—heavy-duty ABS construction with 4-point lateral reinforcement, sand-coated finish, and materials rated for decades of professional use supporting up to 350 lbs. HEAVY-DUTY ABS Impact resistant — absorbs shocks without cracking Chemical resistant — unaffected by stage chemicals, cleaners Temperature stable — maintains strength in cold/hot environments Fatigue resistant — no stress cracking from repeated loading 4-POINT REINFORCEMENT Lateral bar support — prevents flex under weight 350 lb capacity — matches chair weight rating Distributed loading — no weak points or stress concentrations Professional grade — built for decades, not years SAND-COATED FINISH Scuff resistant — protects stages, floors, equipment Abrasion resistant — maintains appearance through years of contact Non-marking — won't leave traces on surfaces Textured grip — prevents slipping during adjustment MATERIAL SCIENCE: ABS (Acrylonitrile Butadiene Styrene) is the same engineering plastic used in automotive dashboards, safety helmets, and protective equipment—chosen for its exceptional impact resistance, dimensional stability, and fatigue resistance under repeated loading. The 4-point lateral reinforcement distributes weight forces across the entire ring structure instead of concentrating stress at mounting points. The sand-prep coating adds a textured surface layer that prevents scuffing damage to expensive stages, floors, and equipment while maintaining the ring's structural integrity. This is engineered equipment, not office furniture accessories. TOOL-FREE HEIGHT ADJUSTMENT FOR EVERY USER Quick adjustment accommodates different cylinder heights and user leg lengths HOW FOOT RING ADJUSTMENT WORKS 1 Loosen the adjustment knob The foot ring mounts to the chair cylinder with a locking collar mechanism. Twist the adjustment knob counterclockwise (lefty-loosey) to release the collar—no tools required, just finger pressure on the knob. 2 Slide the foot ring to desired height With the collar loosened, the foot ring slides freely up and down the cylinder. Raise it higher for taller users or when using the tall/X-tall cylinder. Lower it for shorter users or when using the short cylinder. The goal: your feet rest comfortably on the ring when seated at working height, with knees bent at approximately 90-110 degrees. 3 Tighten the knob to lock position Once positioned correctly, twist the knob clockwise (righty-tighty) to lock the collar. The ring will hold position firmly under full user weight. Total adjustment time: under 30 seconds. This makes the Stealth Chair ideal for shared workstations or rental scenarios where multiple users need different foot ring heights. PROPER FOOT RING HEIGHT: Correct foot ring positioning means your feet rest comfortably on the ring with your knees bent at 90-110 degrees when seated at your normal working height. Your thighs should be approximately parallel to the floor or angled slightly downward. If your knees are bent more than 110 degrees (ring too high), lower the ring. If your knees are barely bent or your legs angle sharply downward (ring too low), raise the ring. Perfect positioning eliminates thigh pressure and allows natural leg angles. MULTI-USER FLEXIBILITY: The tool-free adjustment system makes the Stealth Chair ideal for shared studio environments, rental applications, and facilities with multiple operators. Each user can dial in their perfect foot ring height in under 30 seconds—no allen keys, no wrenches, no fighting with fixed-height accessories. Quick adjustment means users actually bother to adjust for proper ergonomics instead of suffering through incorrect positioning. PROFESSIONAL SCENARIOS WHERE FOOT RINGS ARE ESSENTIAL LIGHTING DESIGN & PROGRAMMING: Lighting consoles sit at standing height—you're working at 40-48 inches off the floor for 8-12+ hour programming sessions. Without a foot ring, this position is torture. Your feet dangle, your thighs compress, circulation stops, and you're fighting discomfort instead of focusing on creating stunning looks. The foot ring transforms an elevated nightmare into ergonomic comfort. Lighting techs don't use Stealth Chairs without foot rings—it's mandatory equipment, not optional. FOH AT STANDING CONSOLES: Many festival and venue FOH positions use standing-height digital consoles—DiGiCo SD-series at 42-46 inches, Avid S6L at similar height, Meyer Galileo at standing positions. You need elevated seating to work these consoles properly, and elevated seating without foot support is miserable. The foot ring lets you work all-day festival runs or multi-night residencies without leg fatigue or circulation issues. When you're mixing 8-12 bands back-to-back, ergonomic support isn't luxury—it's how you survive the gig. STAGE/PLATFORM WORK: Working on risers, stages, or elevated platforms means your chair height relative to the floor varies depending on platform height. A foot ring provides consistent foot support regardless of how high the platform raises you off the actual floor. Whether you're 6 inches or 24 inches above stage level, your feet rest on the ring at the correct height for your legs—the platform height becomes irrelevant to your ergonomics. BROADCAST & VIDEO CONTROL: Video switchers, graphics controllers, and broadcast consoles often sit at elevated heights to accommodate multiple monitor displays and equipment racks. You're working elevated for entire game broadcasts, live events, or production days. Foot rings are standard equipment in professional broadcast facilities—because engineers who tried working elevated without foot support learned the hard way that it's physically unsustainable beyond 2-3 hours. MULTI-HEIGHT STUDIOS: Some facilities have multiple workstations at different heights—tracking room at desk height, mix position at console height, mastering suite at intermediate height. The foot ring adjusts to accommodate all positions. Lower it for desk-height work, raise it for console work, position it mid-range for mastering. One chair, one foot ring, infinite height configurations. This flexibility is why major studios standardize on Stealth Chairs with foot rings. SHARED/RENTAL ENVIRONMENTS: Rental facilities, shared studios, and educational institutions serve users with vastly different leg lengths. A 5'2" user needs the foot ring positioned differently than a 6'4" user—even at the same cylinder height. The tool-free adjustment means every user can dial in proper foot support in seconds. No compromise, no "close enough," no fighting with fixed-height accessories. Everyone gets proper ergonomics, every session. REPLACEMENT & UPGRADE: WHEN YOU NEED A NEW FOOT RING Foot rings are durable enough to outlast most chairs—but accidents happen, configurations change, and sometimes you just need a replacement. Here's when Stealth Foot Rings come into play: REPLACEMENT SCENARIOS: Physical damage: Cracked or broken ring from impact during transport or stage setup Lost/missing component: Bought used chair missing foot ring, or lost ring during tour Worn adjustment mechanism: Collar no longer holds position firmly after years of daily adjustment Adding elevated capability: Originally configured for desk height, now need elevated work capability Upgrading older chairs: Retrofitting newer-generation foot ring to older ErgoLab chairs Spare for tour/rental: Keep backup foot ring on hand for instant replacement if primary fails Multi-configuration setup: Want dedicated foot rings for different cylinder heights to avoid constant adjustment Here's what makes Stealth/ErgoLab foot rings better than generic replacements: they're engineered specifically for our cylinder diameters and chair weight ratings. Generic drafting stool rings either don't fit properly (wrong cylinder diameter), lack sufficient weight capacity (flex under professional use), or use cheap materials that crack within a year. Our foot rings are OEM components—same parts that ship with new chairs, same quality standards, same durability. SERVICEABILITY PHILOSOPHY: We sell replacement foot rings because professional equipment should be repairable for decades. When a $35 component fails or gets lost, you replace that component—not the entire $750 chair. This is the same philosophy behind offering replacement cylinders, casters, arms, bushings, and every other serviceable part. Buy once, maintain forever, refuse planned obsolescence. TECHNICAL SPECIFICATIONS Material: Heavy-Duty ABS Plastic Construction: 4-Point Lateral Reinforcement Finish: Sand-Prep Coated Weight Capacity: Up to 350 lbs Adjustment: Tool-Free Knob Mechanism Height Range: Fully Adjustable on Cylinder Compatibility: All Stealth & ErgoLab Chairs UNIVERSAL COMPATIBILITY: Compatible with all Stealth and ErgoLab chair models and all cylinder configurations (Short, Tall, X-Tall). This is a genuine OEM component featuring the same heavy-duty ABS construction, 4-point reinforcement, and sand-coated finish as factory-installed foot rings. Mounts to standard Stealth/ErgoLab cylinders using the locking collar adjustment system. No adapters, no modifications, no compatibility questions—it just works. INSTALLATION GUIDE Simple installation takes under 2 minutes—no tools required MOUNTING THE FOOT RING TO YOUR CHAIR 1 Remove chair seat from cylinder (if installed) If your chair is already assembled, flip it over or tilt it to access the cylinder. Pull the seat assembly off the cylinder top—it should slide off with moderate upward force. If installing on a new chair, skip this step and work directly with the bare cylinder. 2 Slide foot ring onto cylinder from top The foot ring collar opens wide enough to slide over the cylinder. Start from the top (small end) of the cylinder and slide the ring down toward the base. The locking collar should face upward so the adjustment knob is accessible when the chair is assembled. 3 Position ring at initial height Position the foot ring approximately where you think it should sit—this doesn't need to be perfect since you'll fine-tune the height later when seated. Generally, position it 8-12 inches from the cylinder base as a starting point. 4 Tighten collar to secure foot ring Twist the adjustment knob clockwise to tighten the locking collar around the cylinder. Tighten firmly—the ring needs to support your full foot weight without slipping. Test by pressing down hard on the ring to ensure it doesn't slide. 5 Reinstall seat and adjust height as needed Slide the seat assembly back onto the cylinder top. Sit in the chair and test the foot ring height. If adjustment is needed, follow the height adjustment procedure (loosen knob, slide ring, retighten). Total installation time: under 2 minutes. INSTALLATION TIP: If you're installing a foot ring on a chair that's already in position and difficult to flip over, you can thread the ring up from the bottom of the cylinder before the chair base is attached. Slide ring onto cylinder, install base and casters, position foot ring, then install seat. Either method works—choose whichever is easier for your setup situation.
