Engineering & Performance Highlights

Seamless Cleanable Upholstery & Chemical Resistance

Non-Porous Molded PU: Manufactured with high-density self-skinning polyurethane foam that resists spills, common laboratory disinfectants, alcohol, and mild acids/alkalis.

Hygienic Surface Design: Smooth, seamless edges and minimal joint exposure prevent dirt, biological residues, and dust accumulation, simplifying daily decontamination.

Complete ESD System Protection (Not Just a Conductive Seat)

100% Grounding Pathway: Continuous static-dissipative path from the conductive seat/backrest, through the conductive gas spring and aluminum base, down to conductive casters or drag chains.

Strict Electrical Compliance: Engineered and verified to meet IEC 61340-5-1 and ANSI/ESD STM12.1 standards with a total system resistance of 10^6 to 10^9 Ohms.

Certified ISO Cleanroom Seating Construction

Zero Particle Emission: Designed specifically for controlled environments without exposed foam, porous textiles, or unsealed seams that release airborne particles.

ISO 14644-1 Compatibility: Suitable for use in ISO Class 5 (Class 100) cleanrooms, featuring polished aluminum bases and sealed pneumatic cylinders.

Ergonomic Adjustability for Extended Shift Comfort

Pneumatic Height Control: Smooth class-4 gas lift system allowing quick adjustment for operators across varying bench heights.

Posture Support: Optional adjustable backrest angle (+10 degrees to -6 degrees), seat tilt mechanism, and height-adjustable chrome foot ring (400 mm diameter) to relieve lower-back and leg pressure.

Technical Specifications

Parameter	Specification	Procurement Value
Category	Industrial & Laboratory Seating	Suitable for laboratory benches, industrial workstations, inspection stations, ESD areas, and other professional work environments.
Seat Height Adjustment	Low: 440–580 mmMedium: 500–680 mmHigh: 560–810 mm	Three height ranges allow buyers to match the seating to different desk, laboratory bench, counter, and high-workstation heights.
Seat Pan Dimensions	Standard: 430 × 410 mmRound Stool: Ø330 mm	The rectangular seat provides broader support for extended work, while the compact round stool is suitable where mobility and space efficiency are priorities.
Backrest Dimensions	400 × 300 mm, ergonomic contoured profile	Provides back support while maintaining a relatively compact profile for laboratory and industrial workstations.
Gas Lift Cylinder	Class 4 heavy-duty pneumatic liftStroke options: 150 mm / 260 mm	Class 4 cylinders provide a higher-load configuration for professional seating. Different stroke lengths allow the chair to be matched to standard and elevated workstations.
Base Type	5-star die-cast aluminum alloy: Ø600 / Ø640 mmReinforced nylon: available	Five-star bases distribute the load across multiple support points. Aluminum provides a rigid premium option, while reinforced nylon offers a lighter alternative.
Mobility Options	Nylon twin-wheel castersESD conductive castersSoft PU casters for hard floorsStationary glides	Allows the seating configuration to be matched to the floor type, mobility requirement, cleanroom/ESD environment, and workstation layout.
Weight Capacity	Tested static/dynamic load up to 150 kg (330 lbs)	Provides a defined load rating for procurement and project specification rather than relying on a general "heavy-duty" claim.
Color Options	Industrial BlackRoyal BlueESD Dark GreyCustom OEM colors	Standard colors support regular production, while custom shades allow distributors and OEM customers to align seating with their brand or facility design.

Quality Control & Factory Testing Protocols

Static Load & Impact Testing:

Base and cylinder tested under 150 kg static load and drop-impact tests per ANSI/BIFMA X5.1 standards.

Surface & System Resistance Testing:

100% inspection of ESD chairs using megohmmeters to verify static dissipation (10^6 - 10^9 Ohm).

Pneumatic Lifecycle Testing:

Gas lift cylinders subjected to 100,000 continuous cycling tests under load to ensure smooth elevation without pressure loss.

Abrasion & Chemical Exposure Check:

Molded PU seats tested against continuous wiping with isopropyl alcohol and standard lab detergents.

OEM & Private Label Services

Custom Brand Integration:

Custom logo laser-engraving or screen-printing on backrests, seat undersides, and shipping cartons.

Component Customization:

Mix-and-match gas lifts, base materials, foot rings, armrests, and specialized casters/glides to fit regional tender requirements.

Knock-Down (KD) Export Packaging:

Compact, reinforced 5-ply corrugated export cartons designed to maximize container space (40HQ) and prevent transit damage during LCL or ocean freight.

Spare Parts Continuity:

Guaranteed 10-year factory availability for replacement gas springs, casters, bases, and foot rings to simplify your after-sales support.

FAQ

Q: What is the advantage of molded PU over vinyl or fabric in laboratory seating?

A: Molded polyurethane (PU) is non-porous, waterproof, and puncture-resistant, making it superior for harsh lab environments. Unlike fabric, it does not trap particulate contaminants, and unlike standard vinyl, it withstands aggressive chemical disinfectants and daily heavy wear without peeling.

Q: Why is a complete grounding path required for an ESD chair?

A: An ESD seat cushion alone cannot discharge static electricity safely. If the gas cylinder, base, or casters are insulating, static charge remains trapped on the chair, risking electrostatic damage to sensitive electronics. Our ESD seating provides a continuous conductive pathway from seat to floor surface.

Q: Which base mobility option should I choose: casters or fixed glides?

A: Choose casters for workstations requiring frequent lateral movement, such as multi-instrument analytical benches. Choose glides for high-bench chairs, microscopy stations, or precision weighing areas where unwanted chair movement poses safety or operational risks.

Q: Can you customize seat height ranges for specific lab bench heights?

A: Yes. We offer multiple gas-lift cylinder stroke lengths (150 mm, 200 mm, 260 mm) to perfectly match desk-height benches (750 mm), counter heights (900 mm), or standing-height laboratory benches (1050 mm).

Q: What documentation do you supply with OEM or bulk shipments?

A: We provide complete technical datasheets, ANSI/BIFMA load test reports, ESD resistance measurement certificates, cleanroom particle compliance reports (where applicable), user assembly guides, and commercial factory invoices.
