Bed Bath & Beyond · Stain-Resistant Bed Sheets
The Gray Barn Sleeping Hills 3M Microcell All Season Moisture Wicking Lightweight Sheet Set
Lower concern than treated apparel, but 3M's coating formula not publicly disclosed, ask brand directly.
This is a polyester sheet set with 3M Microcell moisture-wicking technology. The exact chemical composition of the Microcell treatment is proprietary and not disclosed on the product or by Bed Bath & Beyond.

The full breakdown
What it's made of and why it matters
This sheet set is a polyester blend treated with 3M Microcell, a proprietary moisture-wicking technology applied as a surface coating or finish. Polyester itself is a synthetic polymer; the concern here centers on the resins and chemical finishes used during manufacturing to create the moisture-wicking and stain-resistant properties. 3M has not publicly disclosed the full chemical formula of Microcell, making it impossible to rule out PFAS or other persistent finishes. The polyester manufacturing process typically involves formaldehyde-based resins for wrinkle resistance and durability, which can off-gas over time especially when new.
The brand's record and disclosure
Bed Bath & Beyond (now operating under bankruptcy restructuring post-2023) has not published detailed chemical disclosure policies or environmental/safety certifications for bedding products. The brand does not appear on publicly available lists of retailers with strong PFAS commitment or polyester finish transparency. No recalls or public controversies specific to this product line are on record. However, the lack of proactive disclosure about coating chemistry is a red flag relative to competitors offering third-party certifications like OEKO-TEX or Global Organic Textile Standard.
How it compares in its category
Stain-resistant polyester sheets often use PFAS-based water and oil repellents, but this product scores relatively lower on PFAS concern (75/100) than typical treated apparel, likely because sheets are not as body-proximate or frequently laundered as clothing. However, many competitors now offer alternative finishes (silicone-based or PFAS-free certifications) or cotton blends with less aggressive finishing. The undisclosed 3M formula places this product in a middle tier: not the worst-in-class but not transparent enough to rival higher-end alternatives with published third-party testing.
If you buy it
Wash 2-3 times before first use to reduce formaldehyde off-gassing and loose fiber shedding. Avoid hot water (use warm or cool) to minimize coating degradation and microplastic release from polyester fibers. Air dry when possible; if machine drying, use low heat to preserve the moisture-wicking treatment and prevent accelerated breakdown of synthetic fibers. Replace after 2-3 years or if the coating begins to pill, flake, or loses water-repellent performance; degraded coating increases microplastic shedding risk.
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.”
Formaldehyde-based finishing resins
Polyester textiles routinely use formaldehyde-containing resins for wrinkle resistance and durability. New sheets are prone to off-gassing; initial odor or eye irritation when unpacking is a sign of residual formaldehyde. Multiple wash cycles before use significantly reduce this exposure.
Undisclosed proprietary coating chemistry (3M Microcell)
3M has not publicly revealed the full chemical composition of Microcell. While the product scores lower on PFAS risk than many alternatives, the lack of transparency means persistent or allergenic chemicals cannot be ruled out. Direct contact with 3M or Bed Bath & Beyond for full ingredient disclosure is advisable for sensitive individuals.
Microplastic shedding from polyester fibers
Polyester textiles shed microplastic fibers during washing and wear, especially as the material degrades. Moisture-wicking coatings can accelerate fiber breakdown over time if exposed to high heat, mechanical stress, or UV light. Using low heat, gentle cycles, and replacing sheets within 2-3 years reduces cumulative microplastic load.
Coating degradation and loss of water/stain repellency
The 3M Microcell finish is not permanent. Repeated laundering, heat, and agitation gradually wear away the coating, especially if hot water or high-temperature drying is used. Loss of coating integrity can expose underlying polyester to faster degradation and increased microplastic release.
Azo dyes or heavy metals in fabric colorants
No specific test results or recalls for azo dyes or pigment contamination in this product are on record. However, Bed Bath & Beyond does not publish dye safety certifications for sheets, so third-party testing history is unavailable. Gray colorant is generally lower risk than bright synthetic dyes, but no guarantee exists without certification.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
