Key Benefits
- More room, more support at height — a larger 440 × 420 mm seat and 380 × 320 mm backrest give operators more seating area and back support than the standard LS014.
- Reaches the tallest workstations in the series — the export-grade gas lift adjusts to 880 mm with foot cups or 900 mm with wheels, covering high benches that other chairs can’t.
- A foot ring that makes tall seating usable — supports the legs at full height, so long shifts at elevated benches stay comfortable rather than tiring.
- 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 — single-piece molded PU foam and an easy-clean, scratch-resistant surface suit static-sensitive clean areas.
Why the JH-LS017 Is the Premium Choice
“Premium” is easy to claim and hard to prove. Here, the evidence is in the numbers.
Compared with the standard LS014, the LS017 gives you a larger seat (440 × 420 mm versus 380 × 380 mm) and a larger backrest (380 × 320 mm versus 350 × 250 mm). That extra area matters at an elevated bench: more of the operator’s weight is supported, the back has more to lean into, and the sit stays comfortable across a longer session. The height range goes further too — up to 900 mm with wheels — so it reaches the tallest work surfaces in the line.
The molded PU foam is shaped to follow the body’s natural contours, so support feels even rather than flat, and the surface resists light scratches and wipes clean fast. Put simply: the LS017 isn’t the “nicer-looking” chair — it’s the bigger, taller, more supportive one, built for operators who sit at high benches long enough to feel the difference.
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-LS017, it’s a core part of how the chair works.
At full height, the operator’s feet won’t reach the floor — that’s simply what happens on a chair built for tall benches. Without support, legs dangle, circulation suffers, and fatigue sets in fast. The steel pipe foot ring, with its cross-shaped coated frame, gives the legs a stable resting point at height. That’s the difference between a tall chair someone can sit in all day and one they can’t.
So when you look at the JH-LS017, don’t read the foot ring as an add-on. At these seat heights, it’s what makes a premium tall chair genuinely usable for real, shift-long work.
Key Features
- Single-piece PU foam seat (440 × 420 mm) — a roomy, secure surface with an anti-slip pattern for comfortable, all-shift seating.
- PU foam backrest (380 × 320 mm) — a larger, more supportive back with a matching anti-slip pattern.

- 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-LS017 is built for premium, elevated, static-sensitive workstations where seat height, support area, and ESD safety all matter:
- Elevated benches that need more support — high work surfaces where operators want a larger, more comfortable seat than a standard tall chair provides.
- Long-seated work at tall stations — where users remain seated at elevated benches long enough to benefit from extra room and back support.
- High assembly and inspection stations — electronics work at raised benches needing ESD control and dependable comfort.
- Clean production lines — dust-free, static-sensitive lines where operators need a taller, better-supported 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 tall, the work is static-sensitive, and you want the most supportive seat in the range, the LS017 is the right tier.

FAQ
What makes the JH-LS017 a premium chair?
The upgrade is in the measurements, not the marketing. Compared with the standard LS014, the LS017 has a larger seat (440 × 420 mm versus 380 × 380 mm), a larger backrest (380 × 320 mm versus 350 × 250 mm), and the tallest height range in the series — up to 900 mm with wheels. That extra seating area and back support make a real difference during long sessions at elevated benches, and the contoured molded foam adds even, comfortable support. It’s the biggest, tallest, most supportive ESD chair in the line.
How is the JH-LS017 different from the JH-LS014?
Both use molded PU foam and deliver anti-static seating for tall benches — but the LS017 is the premium step up. It has a larger seat and backrest, a taller height range (up to 900 mm versus the LS014’s), and a more contoured, supportive shape. The LS014 is the practical, standard tall-bench option: it still reaches high work surfaces and offers solid ESD performance, just with a smaller seat and a more basic build. Choose the LS017 for maximum room and support at height; choose the LS014 for a dependable, everyday tall-bench chair.
How is the JH-LS017 different from the JH-LS037?
They solve different problems. The LS017 is built around tall benches — a big height range, a foot ring, and generous molded-foam support for elevated, static-sensitive stations. The LS037 is a standard-height ergonomic chair with padded armrests, designed for long-seated comfort at normal bench height. They’re not simply higher- and lower-tier; they’re the premium picks for two different work setups. Choose the LS017 for tall-bench work and the LS037 when armrests and standard-height ergonomic comfort matter most.
Does the JH-LS017 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 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.
Why does the foot ring matter so much on this chair?
Because at tall seat heights, the operator’s feet won’t reach the floor, and unsupported legs cause fatigue fast. The steel pipe foot ring provides the legs with a stable resting point at height, which makes the chair usable for a full shift at an elevated bench. On the JH-LS017, it isn’t an optional extra; it’s a core part of how a tall chair actually works in practice.
What is the height adjustment range?
The JH-LS017 uses an export-grade gas lift with the tallest range in the series. With foot cups, it adjusts from 680 mm to 880 mm; with wheels, from 700 mm to 900 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 are the seat and backrest made of, and how comfortable are they?
The seat and backrest are made of single-piece molded PU foam with an anti-slip pattern. At 440 × 420 mm, the seat is generously sized, and the 380 × 320 mm backrest provides ample support for long sessions. The foam is contoured to follow the body’s natural curves, so support feels even rather than flat, and the surface resists light scratches and wipes clean quickly, holding its finish over time.
Is the JH-LS017 suitable for cleanrooms and dust-free work?
Yes. The chair is designed for dust-free and controlled environments. Its single-piece molded PU foam construction and easy-clean surface help keep particle generation low, and its built-in anti-static performance suits static-sensitive clean areas in electronics, pharmaceutical, and technical settings. If you have specific cleanliness or ESD standards to meet, share them, and we’ll confirm the right configuration.
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 a five-star tapered base (300 mm diameter) for a wide, steady footing, with high strength, wear, corrosion, and impact resistance for a long service life. Cleaning is simple too — the molded PU foam surface wipes down quickly and resists light scratches, so it keeps its appearance in busy, clean areas and workshops.
