8007 Gray Mesh Back/ Fabric Seat Desk Chair with Flip Up Arms
Lower concern for PFAS, typical office furniture without obvious stain/water treatments, but brand discloses nothing.
This is a standard office chair with mesh and fabric upholstery, the type of product where PFAS risk is lower than in treated performance textiles or water-resistant coatings. Seventh Tree provides no public disclosure about PFAS, materials, or certifications, which limits confidence.

Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This chair uses polyester and nylon mesh for the backrest and a fabric cushion seat over a standard metal/plastic frame. Polyester and nylon are stable synthetic polymers that do not leach chemicals under normal office conditions (room temperature, no direct heat or liquid submersion). The main consideration is volatile organic compound (VOC) off-gassing typical of new upholstered office furniture, which dissipates within days to weeks with adequate air circulation.
The brand's record and disclosure
Seventh Tree does not publicly disclose materials testing, certifications, or chemical safety policies based on available information. The brand maintains no visible stance on flame retardants, formaldehyde resins, or restricted substances. Absence of third-party certifications (such as Greenguard or OEKO-TEX) is typical for budget office seating but means independent verification of chemical content is unavailable to consumers.
How it compares in its category
Mesh back office chairs at this price point typically use untreated polyester and nylon without disclosed flame-retardant treatments. This product sits in the mainstream commodity segment; it offers no known advantage or disadvantage versus similar branded alternatives from competitors like AmazonBasics or Furmax. Higher-end options often carry environmental certifications; budget models like this one do not, reflecting cost rather than inherent unsafety.
If you buy it
Unbox the chair in a well-ventilated space (open windows, fan running) for 24 to 48 hours to allow initial VOC off-gassing to disperse before prolonged daily use. Do not expose the fabric to sustained heat (direct sunlight, heat lamps, or heaters) as synthetic fabrics can degrade. Spot-clean spills immediately with mild soap and water; avoid bleach or harsh solvents. Replace the chair if seams split, foam compresses unevenly, or mesh tears, as these indicate structural fatigue rather than a safety trigger.
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.”
Volatile organic compound (VOC) off-gassing from polyester/nylon upholstery
New synthetic mesh and fabric cushioning typically emit low-level VOCs (aldehydes, solvents) for days to weeks. This is common across the category and poses minimal risk with normal ventilation but may trigger odor sensitivity or respiratory irritation in people with chemical sensitivities.
Formaldehyde resins in fabric finishing or foam binders
No recall or disclosed use of formaldehyde-based finishes is on record for Seventh Tree office chairs. However, the brand does not certify materials, so presence cannot be ruled out. If formaldehyde is present, typical office chair use does not generate exposure risk comparable to high-temperature cooking or direct skin contact.
Flame retardant chemical residue in foam cushion
Office chairs sold in the US typically contain flame-retardant foam to meet federal flammability standards (16 CFR 1632/1633). Seventh Tree does not disclose the specific flame retardant (brominated, phosphorus-based, or mineral). These are generally stable in foam under normal use but shed microparticles if foam degrades or is compressed repeatedly.
Azo dyes in mesh or fabric colorants (gray dye batch variation)
Gray mesh fabric may be dyed with azo dyes, which can release carcinogenic amines if reduced (e.g., with strong alkali or extended moisture exposure). No safety incident is documented for this product. Avoid prolonged soaking or washing in harsh detergent; normal use poses negligible risk.
Antimony in polyester fiber (trace element)
Polyester may contain antimony trioxide as a catalyst used in production. Antimony remains bound in the polymer under normal conditions and is not leached into skin or air in typical office environments. No health incident linked to standard polyester office furniture has been established.
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.
