Kramer 900-00253 Chair-Sedus Se Joy Light Grey Frame Orange Fabric
Standard office chair with no red flags, but Sedus discloses nothing about PFAS in treatments.
This Sedus office chair is a conventional upholstered workplace product with fabric and metal frame. No known PFAS applications are typical in basic office seating, but Sedus makes no public commitments on PFAS avoidance or testing. Confidence is moderate because upholstery dyes, finishes, and treatments are not transparently disclosed.

The full breakdown
What it's made of and why it matters
The Kramer 900-00253 combines a powder-coated steel frame with unspecified synthetic fabric upholstery (likely polyester, nylon, or a blend). Powder-coated steel is a stable, low-leaching finish when properly cured, and the frame itself poses minimal chemical risk. The critical unknown is the fabric fiber type, weave treatment, and finish chemistry, Sedus does not publicly disclose whether the upholstery includes flame retardant treatments, antimicrobial coatings, or water-repellent finishes that could contain concerning additives.
The brand's record and disclosure
Sedus is an established German office furniture manufacturer with no major documented safety recalls or toxic-chemical controversies in public records. However, the brand does not publicly disclose PFAS use in fabric treatments, flame retardants, or stain-guard coatings, and does not advertise third-party certifications (e.g., Greenguard, bluesign) that would independently verify chemical safety. This silence reflects a broader industry norm for mid-range office seating, not a red flag unique to Sedus, but it does limit consumer confidence in the supply chain.
How it compares in its category
The Kramer sits in the mainstream office chair segment: functional, reasonably durable, and chemically opaque. Higher-end competitors (Herman Miller, Steelcase) typically disclose fabric certifications and PFAS policies; lower-cost alternatives often use identical material strategies without the Sedus brand premium. This chair is not exceptional for transparency, but also not an outlier, it represents the default lack of disclosure that characterizes most office furniture under 1,000 euros.
If you buy it
Air out the chair for 24-48 hours in a well-ventilated space upon arrival to off-gas any volatile compounds from transport and manufacturing. Avoid placing it in direct sunlight or near heat sources, as this can accelerate degradation of synthetic upholstery and any applied coatings. Vacuum the fabric regularly and treat spills immediately with water only; harsh cleaners may degrade finishes or release trapped chemicals. If visible wear or coating peeling occurs on the frame after 3-5 years, replacement is appropriate rather than repair.
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.”
Flame retardant chemicals (if applied to fabric)
Many office chair fabrics receive flame-retardant treatments to meet fire codes; Sedus does not disclose whether this chair uses chemical or inherently non-flammable fibers. If chemical FR is present, it could include brominated compounds or chlorinated phosphates, but no specific testing or label warning exists for this model.
Formaldehyde in fabric finishes
Formaldehyde resins are sometimes used in synthetic fabric treatments for wrinkle resistance or sizing. No public testing or recall implicates this chair; modern EU manufacturing typically avoids formaldehyde, but Sedus does not certify this explicitly.
Heavy metals in dyes or pigments
The orange fabric could theoretically contain lead or cadmium in azo dyes, but German and EU manufacturers are subject to REACH regulations that restrict these. No contamination has been documented for Sedus products; risk is low but unverified by the brand.
Volatile organic compound (VOC) off-gassing
New upholstered office furniture commonly releases VOCs from adhesives, dyes, and finishes for weeks after manufacture. The Kramer will likely emit detectable odor initially; ventilation mitigates this, and it is not specific to this model but rather a category-wide baseline.
Coating degradation on steel frame
Powder-coated steel is durable if not scratched or exposed to moisture for extended periods. No defects are documented for Sedus frames; normal wear and abrasion over 5-10 years may expose base metal but does not typically pose acute chemical risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 60% 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.
