Coop Home Goods Ultra-cool Cooling Waterproof Mattress Protector
Avoid until Coop discloses waterproof treatment or provides test results.
This mattress protector uses an unspecified waterproof coating, a typical PFAS application in textiles. Coop does not disclose the coating type or make any PFAS-free claim on product materials.

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 product carries a PFAS safety grade of 30/100 and the manufacturer has not disclosed treatment type. Waterproof mattress protectors are a documented route of PFAS exposure, particularly water-repellent coatings. Absence of test results or certification is a red flag in this product category.
Source, ATSDR ↗Coating degradation and particle shedding
Polyester fabric with any waterproof coating degrades over time with washing and use. Delamination or peeling can release microscopic coating fragments and loose fibers into the sleeping environment. No published durability data is available for this specific product.
Formaldehyde / VOCs
Polyester textiles sometimes incorporate formaldehyde-releasing resins for wrinkle resistance or dye fixation. Coop does not state whether this protector undergoes such treatment. Low-level exposure is typical for polyester goods, but undisclosed processes heighten uncertainty.
Source, ATSDR ↗PFAS
If the waterproof layer uses polyurethane instead of PFAS, it may emit volatile organic compounds (VOCs) during and after manufacture. Silicone coatings are generally lower-risk but also undisclosed. Heat exposure (warm washing, body heat) can increase off-gassing rates.
Source, ATSDR ↗Microplastic shedding from polyester base
Polyester fabric itself releases microfibers with repeated washing and friction. On a mattress protector, the plastic base is not in direct skin contact, reducing inhalation risk, but fibers may settle into bedding and the mattress underneath.
The full breakdown
What it's made of and why it matters
This protector uses polyester fabric with an unspecified waterproof coating. The coating is the critical unknown, waterproof treatments on textiles are commonly applied via fluorochemicals (PFAS), but can also use polyurethane or silicone. Without disclosure from Coop, you cannot verify which chemistry was used. Polyester itself is stable and low-risk, but the coating determines whether this product introduces persistent chemical hazards into your sleep environment.
The brand's record and disclosure
Coop Home Goods has not publicly disclosed the waterproof treatment chemistry on this product or provided third-party test results for PFAS content. The brand maintains no visible commitment to PFAS-free manufacturing standards or transparency initiatives (such as Cradle to Cradle or GOTS certification for this line). This silence is significant because waterproof mattress protectors are a known PFAS exposure vector, and responsible brands in this space have begun proactively testing and labeling.
How it compares in its category
Most conventional mattress protectors fall into this disclosure gap, so Coop is not uniquely poor. However, premium and eco-focused competitors (Helix, Saatva, Avocado) increasingly disclose or certify PFAS-free treatments. Budget alternatives often offer similar opacity. The 'Ultra-cool' branding suggests performance-focused chemistry, which may increase the likelihood of fluorochemical coatings for durability and water resistance.
If you buy it
Request waterproof treatment information from customer service before purchase; document the response. Wash separately at least once before use to reduce potential off-gassing. Use gentle heat only (warm, not hot water; air-dry preferred). Inspect annually for delamination or coating failure; if the waterproof layer begins to crack or peel, replace immediately to prevent polyester fibers and degraded coating particles from entering the mattress. Do not dry-clean or expose to high heat.
