Deep Pocket Mattress Protector - Full
Avoid or contact Brooklinen directly, since mattress protectors commonly use PFAS-based water-repellent coating coatings with no public disclosure.
Brooklinen's mattress protector lists water and stain resistance without specifying coating chemistry. Waterproof mattress protectors typically use fluorinated durability finishes, and no third-party certification or brand PFAS commitment exists; contact the manufacturer before purchase.

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
VOC off-gassing from polyurethane
Polyurethane foam and films can release volatile organic compounds, particularly during manufacturing and initial use. Mattress protectors have minimal direct skin contact and are typically topped by a mattress, reducing acute inhalation risk, but off-gassing may occur in poorly ventilated bedrooms.
Coating degradation and leachate from water-resistant treatment
Repeated washing and body heat exposure can break down the water-repellent coating over time. Degraded coatings may leach residues into bedding contact areas. Without knowing whether the coating is PFAS-based, fluorosilicone, or paraffin-free silicone, the risk profile of degradation products cannot be fully assessed.
Microfiber shedding from polyester blend
Polyester or polyester-blend protectors shed microfibers during washing and use, contributing to environmental microplastic accumulation. This is not an acute health hazard in normal use but represents a broader pollution concern with synthetic textiles.
What’s reassuring
Flame retardants
No public disclosure indicates whether Brooklinen's protector contains added flame retardants. Polyester and polyurethane can be treated with halogenated or brominated retardants for regulatory compliance; none have been reported on this product, but the coating formulation is not public.
Source: EPA ↗Allergenic dyes or processing residues
No specific dye or chemical residue issues have been reported for Brooklinen's protectors. The product is not marketed as OEKO-TEX certified, so chemical finishing standards are not independently verified.
The full breakdown
What it's made of and why it matters
Brooklinen's Deep Pocket Protector is a polyurethane or polyester blend (exact ratio not publicly specified) with a water and stain-resistant topical treatment. The water-repellent coating is the critical unknown: it may be Teflon-type coating-based, silicone-based, or PFAS-based. Polyurethane itself can off-gas volatile organic compounds (VOCs) during initial use and with heat exposure, though mattress protectors are a lower-heat application than cookware or heated textiles. The synthetic fiber construction avoids natural fiber allergen risk but means the protector will not degrade or off-gas cellulose products.
The brand's record and disclosure
Brooklinen does not publicly disclose the specific water-repellent coating (water-repellent coating) chemistry or provide third-party certifications (such as OEKO-TEX or GOTS) for this product. The brand markets sustainability positioning but has not made formal statements on PFAS phase-out or use avoidance. No recalls or safety controversies are on record for this specific protector. The silence on chemical specifics is standard in the mattress-protector category but leaves consumers unable to verify PFAS-free status.
How it compares in its category
Mattress protectors are universally treated for water resistance, and most use either PFAS-based or fluorocarbon coatings. Brooklinen is mid-market positioned; premium alternatives (e.g., Avocado, Naturepedic) often disclose OEKO-TEX certification or explicit PFAS avoidance. Budget competitors (Waterproof mattress pads) rarely disclose either. Brooklinen's lack of transparency places it squarely in the unclear-risk middle; it is neither a known offender nor a verified safe option.
If you buy it
Unpack and air the protector in a well-ventilated space for 24-48 hours before use to allow any residual manufacturing VOCs to dissipate. Wash before first use with warm (not hot) water and mild detergent; avoid bleach and fabric softeners, which can degrade the water-resistant coating. Expect to replace every 3-5 years depending on washing frequency and visible wear or delamination. If you have sensitivities to chemical odors or suspect PFAS exposure is a concern, contact Brooklinen directly to request water-repellent coating composition before purchase.
