Key Features
- Reinforced PU foam round seat, 320 mm diameter, 25 mm thick — molded polyurethane over an internal support layer for added structure and durability.
- Internal support layer — eucalyptus board, steel plate, or plastic plate, selected by configuration — to keep the seat firm and hold its shape during daily use.
- ESD surface and system resistance, 10⁶–10⁹ Ω — meets standard anti-static requirements (conductive casters or foot cups required).
- Conductive PU surface — helps reduce static-related dust attraction and is suited to cleanliness-sensitive work areas.
- Anti-slip ring on the seat top — helps keep clothing from sliding during precise, static-sensitive tasks.
- Steel base with epoxy powder coating or electroplated finish — corrosion-resistant footing for daily use.
- Export-grade pneumatic gas lift — reliable, single-lever height adjustment through frequent daily cycles.
- One-piece electroplated five-star base, 240 mm diameter — a seamless, stable footing with no weak joints.
- PA casters with metal conductive chain — smooth movement plus reliable static discharge; fixed foot cups optional.
Why Choose This Stool
For procurement teams, the JH-LS019 pairs anti-static performance with a reinforced seat and clean-area suitability in one hardworking stool:
- Built for controlled environments. A conductive PU surface that resists static-related dust attraction suits cleanliness-sensitive labs, electronics lines, and controlled workspaces.
- Reinforced for longer life. The internal support layer keeps the seat firm and holds its shape under daily contact, so it resists sagging and stays comfortable over time.
- Configurable to your floor. Choose conductive casters for mobility or fixed foot cups for a stationary setup, and specify the height range that fits your benches.
- Low upkeep. The molded PU surface wipes clean quickly and resists minor scratches, keeping routine maintenance fast and simple.
- Factory-direct value. Manufactured in-house at Jiahong Laboratory, with consistent unit-to-unit quality, volume pricing, and OEM/ODM support.
Applications
The JH-LS019 suits static-sensitive and cleanliness-sensitive settings where a compact, reinforced seat is a priority:
- Cleanrooms and controlled environments
- Electronics factories and assembly lines
- Laboratories and research centers
- Healthcare and pharmaceutical spaces
- Quality-control and inspection stations

Related Models
| Model | Best For | Key Difference |

Frequently Asked Questions
Does the JH-LS019 meet anti-static (ESD) requirements?
Yes. The stool maintains surface and system resistance at 10⁶–10⁹ Ω, meeting standard anti-static requirements and supporting gradual, controlled static dissipation. The anti-static function is built into the polyurethane seat rather than applied as a surface treatment. To keep the full system within range, use conductive casters or foot cups; the casters include a metal conductive chain for reliable discharge.
Is the JH-LS019 suitable for cleanroom and controlled environments?
Yes. The conductive PU surface helps reduce static-related dust attraction, so the seat stays cleaner between wipe-downs and suits cleanliness-sensitive work. That combination of static control and low dust pickup makes it a good fit for cleanrooms, electronics assembly, and other controlled spaces where particle control matters as much as ESD control. If your facility works to a specific cleanroom class, let our team know so we can confirm the right setup for your requirements.
What is inside the seat, and why does it matter?
The seat isn’t just foam. The molded polyurethane surface wraps an internal support layer — eucalyptus board, a steel plate, or a plastic plate, depending on your configuration — that gives the seat real structure beneath the cushion. That reinforcement helps the seat keep its shape and withstand daily use without sagging, so you get cushioned comfort with the durability of a solid core. Tell us your preferred layer when you order, and we’ll build the stool to match.
What is the height adjustment range?
The export-grade gas lift adjusts from 410 to 560 mm with foot cups, or 440 to 590 mm with casters. This range suits standard lab benches and workstations, and a simple lever lets staff set a comfortable height for a variety of tasks.
What caster and foot-cup options are available?
The stool can be fitted with high-strength, wear-resistant PA casters that include a metal conductive chain for smooth movement and reliable static discharge. If you prefer a stationary setup, fixed foot cups are available instead. A range of caster types is also available to match your floor. Note that conductive casters or foot cups are needed to maintain the full ESD system.
How does the JH-LS019 differ from the JH-LS001?
Both stools share a 320 mm round PU foam seat, an anti-slip ring, and the same 10⁶–10⁹ Ω resistance band, so they look alike at a glance. The difference is the build: the JH-LS019 adds an internal support layer for added structure and a conductive PU surface designed for controlled, cleanliness-sensitive environments. Choose the JH-LS019 for a reinforced, clean-area stool, and the JH-LS001 for a simpler, general-purpose backless ESD seat.
Does the JH-LS019 have a backrest?
No. The JH-LS019 is a backless stool, which keeps it slim, light, and easy to move under benches and through tight workstations. If you need back support for longer seated work, the JH-LS021 pairs a similar PU foam ESD seat with a short backrest.
Do you offer OEM/ODM and export support?
Yes. Jiahong Laboratory manufactures the JH-LS019 in-house, so we can adjust the base, height range, internal support layer, caster or foot-cup setup, and other specifications to match your project. We offer factory-direct pricing, volume discounts for distributors and lab builders, and reliable export for buyers worldwide.
