Fusion Chair- Puncture Resistant
The Cramer Fusion laboratory chair is configured by Pacific Ergonomics — 25+ years specifying lab and industrial seating for universities, pharmaceutical companies, biotech facilities, semiconductor operations, and production environments nationwide.
The Fusion is one of the few lab chairs built for three demanding environments: standard production, ISO Class 5 cleanroom, and ESD bench work. Getting the right configuration means knowing which environment you’re actually in, what your cleaning protocol demands, whether the ESD grounding path holds all the way to the floor, and whether your bench height calls for a chair or a stool. We work through all of that before anything is ordered, procure the right solution, and assemble and deliver or ship for your team to set up on-site — whichever works best for your operation.
Description
Cramer Fusion Lab Chair Configurations
The Fusion is built for demanding lab environments — not just one. Standard, cleanroom, and ESD versions share the same carbon steel frame, r+™ foam, and puncture-resistant construction. The configuration changes based on what your environment requires. We specify which version fits your application before anything is ordered.
Need a Lab Chair Certified for Cleanroom Use?
The Fusion cleanroom configuration is ISO Class 5 certified. The seamless polyurethane surface sheds no particles, withstands disinfection protocols, and wipes clean without breaking down. The fiberglass-reinforced nylon base keeps contamination risk low. We confirm the configuration is appropriate for your cleanroom class before the order is placed — not after.
Need a Production Floor Chair That Survives Heavy Use?
The Fusion is built for production — 1/8″ puncture-resistant polyurethane covering a 16-gauge carbon steel frame. The non-slip tread keeps forward-leaning workers planted in the chair during focused tasks. All connections are metal-to-metal, and the powder coat is heat-bonded. This is not a standard office chair resold into a production environment. It is built for production from the frame out.
Need an ESD Chair for Static-Sensitive Bench Work?
The Fusion ESD version is certified top-to-floor. ESD polyurethane seat covers, ESD-safe casters or glides, and a 27.5″ polished aluminum base complete the grounding path from the user down through the floor. We confirm resistance values and verify the grounding path is intact for your flooring type before anything ships. The wrong caster breaks the path — we check this before the order goes in.
Not sure which configuration fits your environment? That is exactly what the call is for.
Chair or Stool — Same Construction, Different Height
The Fusion is available in three seat height configurations: desk (chair), desk-to-counter (chair or stool), and high (stool). The choice depends on your bench height and how your team works at it — seated, perched, or standing-assist. We ask about bench height and task posture before specifying the cylinder so you get the right range, not the closest available range.
What Makes the Fusion Different
Three features set the Fusion apart from standard lab seating — and they matter most in demanding environments where users spend full shifts in the chair.
Non-Slip Tread
The Fusion’s non-slip tread keeps forward-leaning users planted in the seat instead of sliding toward the bench. For pipetting, microscopy, precision assembly, and other forward-posture tasks, this means you get lumbar support and back contact throughout — not just when you sit straight.
r+™ Foam Technology
Three inches of r+™ foam under the polyurethane surface. Contoured seat and back cushions distribute weight across the sit bones and support the lower back through an 8-hour shift. This is not the thin foam you find in most budget lab chairs — it is built for people who actually use the chair all day.
Puncture-Resistant Polyurethane
The 1/8″ covering handles punctures, abrasion, and chemical exposure that destroy thinner surfaces over time. The seamless construction means no stitching, no seams, and no place for contamination to accumulate — which is why this surface works across production, cleanroom, and ESD environments.
If your team is experiencing discomfort, fatigue, or injuries and you’re not sure seating alone is the fix, Pacific Ergonomics offers ergonomic lab assessments and industrial ergonomic assessments as separate services. A full evaluation identifies exactly where the MSD risk is — workstation layout, posture, task type, and current seating — before you spend on solutions.

Pacific Ergonomics also provides ergonomic lab assessments and industrial ergonomic assessments as separate services — full evaluations of workstation types, postures, tasks performed, and MSD risk across your lab or production floor. If your team is experiencing discomfort or injuries, an assessment identifies exactly where the risk is before you spend on solutions.

Frequently Asked Questions
What is the difference between the standard, cleanroom, and ESD versions of the Cramer Fusion?
The frame, foam, and puncture-resistant polyurethane surface are the same across all three. The cleanroom version uses materials and construction certified to ISO Class 5 and adds a cleanroom-compatible base. The ESD version adds a static-dissipative polyurethane surface, ESD-safe casters or glides, and a polished aluminum base to complete the grounding path top-to-floor. We specify the right version based on your environment and confirm the details — ISO class, ESD resistance values — before the order is placed.
What does the non-slip tread actually do?
It keeps you planted in the chair when you lean forward into a task. Most lab chairs have a smooth seat surface — when users lean toward the bench, they slide forward and lose contact with the backrest. The Fusion's non-slip tread resists that sliding, so you stay in position and the back support actually does something during the parts of the shift where it matters most.
Does the Fusion come with adjustable arms?
Optional adjustable arms are available. Whether they're right for your application depends on bench height and task type. Arms that work at a desk-height bench often restrict reach at a counter-height bench. We work through that before the order goes in.
How do I know which adjustments I actually need?
The Fusion has multiple adjustment options depending on the version — and not every adjustment is necessary for every application. Single-shift, dedicated-user environments need different configurations than multi-shift shared environments. We ask about your team setup, budget, and what problems you're solving before recommending which adjustments to include.
What is the warranty on the Cramer Fusion?
The Fusion carries a 12-year warranty for three-shift use. That covers the frame, mechanism, and components — one of the longest warranties available on a lab chair at this price point. Cramer manufactures in the U.S.
