Key Benefits
- Reaches tall workstations that standard chairs can’t — the export-grade pneumatic rod lifts to 830 mm with foot cups or 850 mm with wheels.
- A foot ring that makes tall seating usable — supports your legs at height, so long shifts at elevated benches stay comfortable.
- Genuine ESD protection — surface and system resistances of 10⁶–10⁹ ohms help protect precision instruments and static-sensitive electronics.
- Built for dust-free, controlled work — molded PU foam and an easy-clean surface suit static-sensitive clean areas.
- Stable at height — a one-piece aluminum alloy five-star base and reinforced steel structure keep the chair steady even at full lift.
Why Bench Height Defines This Chair
Choosing lab seating usually starts with the wrong question: comfort, price, padding. For the JH-LS014, the first question is simpler: how tall is your bench?
High benches, standing-height assembly stations, and elevated production lines leave a standard chair short. Your work surface sits above the reach of a normal seat, so operators end up perching, leaning, or standing when they’d rather sit. The JH-LS014 solves that directly. It adjusts up to 850 mm, so the seat meets the work instead of falling below it.
That taller geometry is the whole point of this chair. Everything else — the molded foam, the ESD performance, the base — supports one core job: keeping operators seated, supported, and static-safe at heights where ordinary chairs don’t work. If your workstations sit high, this is the tier built for them.
The Foot Ring Isn’t an Accessory — It’s Essential Here
On a standard-height chair, a foot ring is a nice-to-have. On the JH-LS014, it’s a core part of how the chair works.
At full height, your feet won’t reach the floor — that’s simply what happens on a chair built for tall benches. Without support, your legs dangle, circulation suffers, and fatigue sets in fast. The electroplated steel foot ring, with its cross-shaped coated frame, gives your legs a stable resting point at height. That’s the difference between a tall chair you can sit in all day and one you can’t.
So when you look at the JH-LS014, don’t read the foot ring as an add-on. At these seat heights, it’s what makes the chair genuinely usable for real, shift-long work.
Key Features
- One-piece molded PU foam seat (380 × 380 mm) — with an anti-skid pattern for a comfortable, secure seating surface.
- Molded PU foam backrest (350 × 250 mm) — matching anti-skid pattern for supportive everyday back comfort.
- Molded PU foam surface — good elasticity, wipes clean quickly, and modified for lower resistance so ESD performance is built into the material.
- ESD surface and system resistance (10⁶–10⁹ ohms) — static control for instrument and electronics protection (conductive casters or foot cups required).
- Tall height range — 630–830 mm with foot cups, or 660–850 mm with wheels, for elevated benches and standing-height stations.
- Electroplated steel foot ring — cross-shaped coated frame, essential leg support at tall seat heights.
- Electroplated steel base with reinforced connector — elastic steel plate connector (60 mm wide, 6 mm thick) with reinforcing rib, built to ergonomic principles.
- Five-star aluminum alloy die-cast legs (320 mm diameter) — formed in one piece for a wide, stable base at height.
- PA casters with metal conductive chain — smooth movement and reliable static discharge (various casters or fixed foot cups optional).
Who It’s For
The JH-LS014 is built for elevated, static-sensitive workstations where seat height and ESD safety both matter:
- Elevated benches and high work surfaces — where a standard chair can’t reach the working height.
- Standing-height workstations — for operators who alternate between standing and seated work at tall stations.
- High assembly stations — electronics assembly and inspection at raised benches needing ESD control.
- Clean production lines — dust-free, static-sensitive lines where operators need a taller seat and a foot ring.
- Controlled and dust-free environments — pharmaceutical, electronics, and technical spaces where static control is essential.
In short, anywhere the bench is too tall for a normal chair, and the work is static-sensitive, the JH-LS014 is the right tier.

Related Models — Which Lab Chair Fits Your Bench?
The chairs in this range answer different needs. The deciding factors are bench height, seated comfort, and whether hygiene or static control leads. Here’s how to choose:
| Model | Best for | Key difference |
|---|---|---|
| JH-LS014 (this chair) | Elevated benches and standing-height stations needing ESD seating | Tall height range (up to 850 mm) with a foot ring for support at height |
| JH-LS035 | Budget-friendly ESD seating with back support at standard bench height | Standard height, compact PU leather seat — a value pick, not a tall-bench chair |
| JH-LS037 | Long, seated work needing ergonomic comfort at standard height | Padded armrests and fuller ergonomics for seated comfort, not bench height |
| JH-LS036 | Hygiene-critical, washdown, and cleanroom spaces | 304 stainless steel for cleanability and corrosion resistance, not ESD or tall reach |
In short: pick the LS014 when your bench is too tall for a standard chair, and the work is static-sensitive; pick the LS035 for value seating at normal height; pick the LS037 for ergonomic seated comfort; pick the LS036 for hygiene-first environments. If you’re unsure, tell us your bench height and whether ESD or cleanability matters more, and we’ll point you to the right model.
FAQ
What makes the JH-LS014 different from a standard lab chair?
Height. The JH-LS014 is built for elevated benches and standing-height workstations, adjusting up to 850 mm — well above the reach of a standard chair. It also includes a foot ring to keep your legs supported when your feet leave the floor at full height. If your work surface sits high and a normal chair leaves operators perching or standing, this is the tier designed for it.
Why does the foot ring matter so much on this chair?
Because at tall seat heights, your feet won’t reach the floor, and unsupported legs cause fatigue fast. The electroplated steel foot ring provides your legs with a stable resting point at height, making the chair usable for a full shift at an elevated bench. On the JH-LS014, it’s not an optional extra; it’s a core part of how a tall chair actually works in practice.
Does the JH-LS014 meet anti-static (ESD) requirements?
Yes. Surface and system resistance are held at 10⁶–10⁹ ohms, which meets standard anti-static requirements and helps protect precision instruments and static-sensitive electronics. The molded PU foam is modified to lower its resistance, so the ESD effect is built into the material rather than added on top. To keep the full system in the ESD range, conductive casters or foot cups are required, and the casters include a metal conductive chain for reliable static discharge.
What is the height adjustment range?
The JH-LS014 uses an export-grade pneumatic gas pole with a tall range. With foot cups, it adjusts from 630 mm to 830 mm; with wheels, from 660 mm to 850 mm. This taller range is what sets it apart from standard lab seating and allows it to accommodate high benches and standing-height workstations that shorter chairs can’t reach.
What environments is the JH-LS014 suited for?
It’s built for elevated, static-sensitive work: high benches and raised work surfaces, standing-height workstations, high assembly and inspection stations, and clean production lines. It also fits dust-free and controlled environments in electronics, pharmaceutical, and technical settings where static control is essential. Anywhere the bench is too tall for a normal chair, and the work is static-sensitive, the LS014 is a strong fit.
What is the seat and backrest made from?
The seat and backrest use one-piece molded PU foam with an anti-skid pattern. The foam has good elasticity, so it gives a comfortable, secure sit while holding its shape through daily use, and it wipes clean quickly to keep maintenance simple. Because the foam is modified for lower resistance, you get comfort and anti-static performance in one surface, without a separate coating or cover.
How is the JH-LS014 different from the JH-LS035?
Both offer ESD seating with a backrest, but they serve different needs — and the main difference is the height geometry, not just the materials. The LS014 features molded PU foam, a larger seat, a tall range up to 850 mm, and a foot ring, making it built for high benches and elevated stations. The LS035 uses a compact conductive PU leather seat at standard height and is positioned as a budget-friendly everyday option. Choose the LS014 for tall-bench work and the LS035 for value seating at normal height.
How is the JH-LS014 different from the JH-LS037?
The LS014 solves bench height and static control; the LS037 solves seated comfort. The LS014 is built around a tall height range, molded PU foam, ESD performance, and a foot ring for elevated stations. The LS037 is a padded ergonomic chair with armrests, designed for long hours of seated comfort at standard bench height. Pick the LS014 for tall, static-sensitive workstations, and the LS037 when armrests and all-day ergonomic support matter most.
What caster and foot options are available?
The standard chair comes with high-strength, wear-resistant PA casters fitted with a metal conductive chain for smooth movement and reliable static discharge. If you’d prefer a stationary setup, fixed foot cups are available, and various caster types can be selected to match your flooring and workflow. Keep in mind that conductive casters or foot cups are needed to maintain the full ESD system. Let us know your preference when you request a quote.
How durable is the chair, and is it easy to clean?
It’s built to stay stable at height. The chair sits on an electroplated steel plate base with a reinforced elastic steel connector and one-piece aluminum alloy die-cast five-star legs (320 mm diameter) for a wide, steady footing. These parts withstand daily use and support a long service life. Cleaning is simple too — the molded PU foam surface wipes down quickly and resists everyday wear, so it keeps its appearance in busy labs and workshops.
