Brooklinen · Mattress Protectors
Deep Pocket Mattress Protector - Queen
Avoid until Brooklinen discloses waterproof treatment chemistry or obtains third-party verification.
Mattress protectors require water-resistant treatments traditionally made with PFAS, but Brooklinen does not publicly disclose coating chemistry or claim PFAS-free status. Without lab testing or credible certification, PFAS risk cannot be ruled out.

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.
Water-resistant/stain-resistant treatment off-gassing
If PFAS-based or solvent-containing, fresh protectors may emit low levels of volatile compounds for days after opening. Airing out for 24-48 hours in ventilation before bed use reduces potential exposure. Brooklinen's silence on treatment type makes definitive assessment impossible.
Microplastic shedding from polyester
Polyester textiles shed microfibers during washing and wear. Mattress protectors shed minimally compared to clothing due to low friction, but washing will release some fibers into wastewater. This is a category-wide issue for polyester, not Brooklinen-specific.
Skin irritation from treatment chemicals or dyes
Undisclosed water-resistant treatment or reactive dyes could theoretically trigger contact dermatitis in sensitive users, particularly if protector is not fully rinsed before use. Pre-wash before first use is advised for any sensitivity history.
What’s reassuring
Polyester antimony catalyst residue
Antimony is used as a catalyst in polyester synthesis but typically remains bound in the polymer chain. No evidence of leaching into skin or washwater from intact mattress protectors under normal use conditions.
Formaldehyde / VOCs
Polyester fabric itself does not use formaldehyde-releasing resin (unlike some cotton wrinkle finishes), so residual formaldehyde is not a documented concern for this material class.

What it's made of and why it matters
This protector is polyester fabric with a water-resistant or stain-resistant topical treatment applied to the surface. Polyester itself is a stable plastic polymer with low inherent toxicity risk under normal use. The treatment chemistry is the material variable of concern: water resistance in textiles is historically achieved with fluorinated compounds (PFAS), silicones, or wax-based coatings. Brooklinen has not publicly disclosed which method they use, which is the primary safety limitation here.
The brand's record and disclosure
Brooklinen is a direct-to-consumer bedding brand known for transparency on materials (thread count, fabric origin) but has remained silent on the specific chemistry of their stain-resistant and waterproof treatments across their product line. No third-party certifications (OEKO-TEX, GOTS) have been publicly claimed for this protector model. No recalls or regulatory actions against Brooklinen mattress protectors are on record.
How it compares in its category
Mattress protectors in this price and material tier typically use either PFAS-based or silicone-based water treatments; few disclose this openly. Some competitors (e.g., Helix, Saatva) offer organic or OEKO-TEX certified alternatives that reduce treatment uncertainty. Brooklinen's protector sits in the mainstream category where treatment chemistry is industry-standard opacity rather than best-practice transparency.
If you buy it
Wash separately in cold water with mild detergent; hot water or fabric softener can degrade water-resistant coatings and potentially release treatment chemicals. Do not dry-clean or use high heat (dryer risk). Replace the protector every 2-3 years or if waterproofing noticeably fails (water beading stops). Air dry or low heat only. If you have sensitivities or live in a PFAS-concerned water district, contact Brooklinen to request treatment chemistry transparency before purchase.
