Brooklyn Bedding Mattress Encasements, Are They Non-Toxic?
Avoid until brand discloses coating chemistry or obtains third-party testing.
Brooklyn Bedding markets these encasements as waterproof and moisture-resistant, functions commonly achieved with PFAS-based durability treatments. The brand provides no public disclosure of coating chemistry or PFAS status, and no third-party verification exists.

Are Brooklyn Bedding Mattress Encasements non-toxic? What it is made of
Brooklyn Bedding encasements are polyester with a proprietary waterproof or moisture-barrier coating (exact chemistry not publicly disclosed by Brooklinen). Polyester itself is stable and low-risk when used as a fabric, but the barrier coating is the critical unknown. Waterproof coatings on textiles commonly rely on fluorochemicals (PFAS) or silicone-based systems; without disclosure, the specific chemistry cannot be assessed. Heat exposure during washing or use may accelerate off-gassing or degradation of the coating polymer, though typical mattress protector use (room temperature, infrequent laundering) keeps this risk minimal.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
The waterproof barrier coating is unspecified by the brand. Fluorochemicals are common in waterproof polyester textiles and persist indefinitely in the body and environment; Brooklinen's silence on composition makes assessment impossible without third-party testing.
Source, ATSDR ↗Coating degradation and chemical release
Without knowing the coating polymer type, long-term thermal or moisture-induced degradation cannot be ruled out. Heat exposure during machine drying, storage in hot climates, or contact with sweat and body oils may gradually break down the barrier; this is a general concern for all coated textiles, not specific to Brooklinen.
Lack of third-party certification and transparency
The brand's refusal or failure to disclose coating chemistry or seek independent certifications (OEKO-TEX, GOTS, PFAS-free seals) is itself a hazard flag. Consumers cannot verify material safety claims, limiting informed decision-making.
What’s reassuring
Microplastics
Polyester encasements can shed microfibers over time, especially with repeated washing. No specific recalls or documented harm linked to Brooklinen encasements, but the risk exists across all polyester bedding protectors; washing in cold water and using a microfiber-capture bag reduces shedding.
Source, EPA ↗Formaldehyde / VOCs
Polyester fabric itself does not contain formaldehyde, but finishing resins applied during manufacturing sometimes do. No recalled or documented cases link Brooklinen encasements to formaldehyde off-gassing; standard polyester processing uses low-formaldehyde or formaldehyde-free methods in most modern facilities.

The brand's record and disclosure
Brooklinen is a direct-to-consumer bedding brand with no major public recalls or safety controversies on record for mattress protectors. However, the brand has not published material safety data sheets (MSDS), third-party certifications (e.g., OEKO-TEX, GOTS), or explicit statements about PFAS avoidance or use in their encasements. This silence on coating chemistry is a red flag in an industry where PFAS-free alternatives are increasingly available and marketed. No evidence of independent testing or transparency initiatives has been identified.
How it compares in its category
Mattress protector encasements vary widely in coating technology. Some brands (notably Helix, Layla, and certain Amazon-sold models) advertise PFAS-free or GOTS-certified polyester; others remain silent. Brooklinen's lack of disclosure places it in the middle of the transparency spectrum and suggests the brand may not prioritize or communicate ingredient safety as a differentiator. Competing products at similar price points often provide more clarity on materials and certifications.
If you buy it
Wash encasements in cool to warm water (not hot) to minimize any potential off-gassing or coating degradation; machine drying on low heat presents lower concern for coating degradation than high heat. Replace every 2-3 years or sooner if the waterproof coating begins to fail (water seeping through despite washing). Ensure the mattress underneath is also protected or ventilated to prevent moisture buildup. If you or household members have respiratory sensitivities, request product testing data from Brooklinen before purchase, or choose a brand with published PFAS-free certification.
