Brooklinen · Mattress Protectors
Brooklyn Bedding Deep Pocket Mattress Protector
Avoid until brand discloses coating chemistry, since mattress protectors commonly use PFAS-based water and stain repellents.
Brooklinen does not publicly disclose the chemical composition of this protector's waterproof and stain-resistant coating. Mattress protectors in this category frequently use PFAS-based durability treatments, and no third-party testing or PFAS-free commitment exists.

Material
Polyester blend with waterproof/stain-resistant coating (composition unspecified)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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.
PFAS
Undisclosed coating chemistry; PFAS-based water repellents remain common in this product category despite regulatory pressure. Graded separately by your assessment, but warrants confirmation from the brand.
Source: ATSDR ↗Volatile organic compound (VOC) off-gassing from coating
Waterproof coatings may off-gas low levels of volatile solvents or monomers, especially in new product and warm conditions. Degree depends on coating type (polyurethane, silicone, fluorine-based) and manufacturing process, neither disclosed here.
Microplastics
Polyester textiles release microfibers with regular washing and friction. Mattress protectors see moderate abrasion during bed-making and laundry. Environmental concern rather than direct health risk, but relevant to product lifecycle.
Source: EPA ↗Lead
Waterproof coatings degrade over 2 to 4 years of use and laundering, especially with high heat or harsh detergents. At that point the protector loses efficacy and may need replacement; degradation itself is not a toxicity risk but signals product lifespan.
Source: ATSDR ↗What’s reassuring
Formaldehyde / VOCs
Polyester textiles can contain formaldehyde-based resins for wrinkle resistance or stiffness. No specific reports of formaldehyde in Brooklyn Bedding mattress protectors, and modern finishes often use non-formaldehyde resins, but unverified here.

What it's made of and why it matters
Brooklyn Bedding's Deep Pocket Protector is a polyester-blend fabric with a waterproof and stain-resistant coating whose chemical composition Brooklinen does not publicly specify. Waterproof coatings on textiles historically relied on PFAS (PFAS "forever chemicals") because fluorine compounds repel both water and oil; however, non-PFAS alternatives now exist. Without transparency on coating chemistry, you cannot determine whether this product uses legacy PFAS, newer fluorine-free repellents, or silicone-based systems. The polyester itself is not inherently hazardous, but the coating is the critical unknown.
The brand's record and disclosure
Brooklinen has not publicly committed to PFAS-free formulations or published detailed chemical composition for their mattress protectors. The brand markets premium bedding with sustainability language but lacks third-party certifications (GOTS, OEKO-TEX, MADE SAFE) that would verify absence of restricted chemicals. No recalls or formal safety controversies for this specific product are on record. The silence on coating chemistry is the primary concern; many mattress protector manufacturers in this price tier similarly withhold this information.
How it compares in its category
Most mid-to-premium mattress protectors (Helix, Purple, Casper) use similar polyester-plus-coating constructions with undisclosed water-repellent chemistry. Untreated cotton or wool protectors eliminate the coating hazard entirely but sacrifice stain resistance and washability. Protectors explicitly labeled PFAS-free or certified by OEKO-TEX or GOTS are available from specialty brands (Naturepedic, Avocado) at similar or higher price points. Brooklyn Bedding's product sits in the mainstream convenience category rather than the safer-disclosure segment.
If you buy it
Wash before first use to reduce potential off-gassing or coating residues. Use warm water and mild detergent; avoid heat drying or high heat, which can degrade the coating and potentially release volatiles. Replace every 2 to 3 years or if the waterproof barrier noticeably degrades (water no longer beads). Store in a cool, dry place; do not fold tightly for long periods, as creasing can crack the coating. If you are sensitive to chemical odors or respiratory concerns, request detailed material safety data from Brooklinen before purchase.
