Knoll Generation Chair, All Features, Adjustable Arms, Black, Blue Fabric Seat
Lower PFAS concern likely; standard office chair with no water/stain treatment signals, but manufacturer discloses nothing.
The Knoll Generation Chair is a conventional office task chair with fabric upholstery and metal frame. No fabric waterproofing, stain resistance treatment, or Teflon-family coating coatings are mentioned in public product specs. Knoll makes no PFAS claims either way, which is typical for office furniture in this category.

The full breakdown
What it's made of and why it matters
The Knoll Generation chair combines a likely aluminum or steel frame with polyurethane foam cushioning and a blue woven fabric seat. The foam is the primary concern for VOC off-gassing in new condition; fabric itself is a standard polyester or polyester-blend weave with no water/stain repellent coating evident in product specs. No ceramic, laminate, or non-stick coatings are used, eliminating hazards tied to Teflon-type coating, lead glazes, or cadmium.
The brand's record and disclosure
Knoll is a major contract furniture manufacturer with a strong sustainability reputation but does not publicly disclose detailed chemical composition or third-party testing for flame retardants, formaldehyde binders, or other VOCs in foam and fabric. The company has not faced major product safety recalls in recent years. Absence of explicit PFAS disclosure is typical for office furniture and does not indicate presence; the lack of stain-guard marketing suggests no intentional PFAS application.
How it compares in its category
Office chairs in this price and quality tier (Knoll is premium) typically use similar polyurethane foam and woven fabric, all of which can release trace VOCs. Knoll's reputation and durability standards suggest better quality control over cheaper alternatives; however, transparency on chemical composition lags behind leaders in certified low-VOC or GreenGuard-certified task seating. The Generation line is mid-range within Knoll's own portfolio.
If you buy it
Air out the chair in a well-ventilated space for 24-48 hours after unboxing to minimize new foam off-gassing. Use it at normal room temperature and avoid prolonged direct sunlight, which can degrade fabric. Clean spills promptly with water or mild soap; avoid harsh solvents that may degrade or strip protective finishes. The chair is designed for standard 8-hour office use; foam and fabric typically remain stable for 5-7 years under normal conditions.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
VOC off-gassing from polyurethane foam
New polyurethane foam cushioning commonly releases volatile organic compounds (mainly aldehydes and solvents) during the first weeks. Knoll does not specify foam formulation or low-VOC certification; off-gassing is typically mild in well-ventilated spaces but may be noticeable in sealed rooms.
Flame retardants in foam or fabric
Office seating often contains flame retardants to meet flammability codes (BIFMA); Knoll does not disclose specific FR chemicals used in the Generation line. No data exists linking this chair to halogenated or concerning FR classes, and the brand's reputation suggests responsible selection.
Formaldehyde binders in fabric glues or foam adhesives
Foam-to-fabric bonding and some fabric finishes may use formaldehyde-releasing adhesives; Knoll does not publish test results. Exposure is minimal during normal use and decays over time, but off-gassing may contribute to overall VOC burden in a new chair.
Azo dyes or heavy metals in blue fabric dye
Knoll is a reputable brand unlikely to use banned azo dyes or arsenic/cadmium dyes; no skin contact hazard is established for woven fabric in normal seating use. Dye migration into sweat is not a documented concern for high-quality commercial upholstery.
Aluminum frame corrosion or leaching
If the frame is aluminum, it is likely anodized or powder-coated to prevent oxidation. No food contact or moisture immersion is involved in chair use, so leaching is not a realistic concern; indoor office conditions do not degrade metal frames significantly over normal lifespan.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
