Coop Home Goods Ultra-cool Waterproof Mattress Protector - Full (54x, Is It Non-Toxic?
Avoid until Coop discloses waterproof coating details.
Coop markets this waterproof mattress protector without explaining what coating it uses or whether it contains PFAS. Waterproof finishes commonly rely on PFAS-based water-repellent coating treatments, though PFAS-free options exist, and Coop provides no transparency.

Is Coop Home Goods Ultra-cool Full (54x non-toxic? What it is made of
This protector uses a polyurethane or TPU (thermoplastic polyurethane) waterproof backing layer, but Coop has not publicly specified which polymer or what chemical additives stabilize it. TPU is generally more breathable and flexible than older polyurethane formulations, but both can leach plasticizers and flame retardants into contact with skin and bedding, especially under warmth and moisture. The 'ultra-cool' designation suggests additives for temperature regulation (phase-change materials or gel particles), which introduce additional unknowns into the coating chemistry.
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.
Flame retardants
Undisclosed additives in the waterproof backing can migrate into bedding and skin, especially under warmth, humidity, and friction. No third-party testing on this specific product has been published; risk is inferred from the material class and Coop's silence on formulation.
Source, EPA ↗Volatile organic compound (VOC) off-gassing from coating
Polyurethane and TPU coatings typically release small amounts of solvents and unreacted monomers, particularly in the first weeks after manufacturing. Coop does not disclose whether the coating is cured to standard levels or whether off-gassing testing has been performed.
Coating degradation and microparticle shedding over time
Polyurethane and TPU degrade under repeated flexing, washing, and thermal cycling. As the coating cracks or peels, it may shed particles into bedding and breathing space. The company provides no guidance on when replacement is necessary.
Thermal stability and heat-induced outgassing
The 'ultra-cool' additives and polyurethane backing may release volatile or semi-volatile compounds under sustained warmth from body heat and high-humidity sleep environments, particularly for hot sleepers or in warm climates.
Flame retardants
Waterproof coatings often incorporate halogenated or organophosphate flame retardants to meet flammability standards. Coop does not disclose whether flame retardants are present or what type; neither does the product comply with OEKO-TEX standards that would exclude persistent or bioaccumulative flame retardants.

The brand's record and disclosure
Coop Home Goods has built a brand around natural-fill pillows and emphasizes transparency on shredded memory foam and plant-based options, but has remained silent on the waterproof coating chemistry in this protector despite multiple product lines using it. The company holds no OEKO-TEX, GOTS, or waterproofing-specific certifications that would independently verify the absence of harmful additives. This silence on a chemical-intensive component is inconsistent with their marketing narrative around safety-conscious design.
How it compares in its category
Waterproof mattress protectors universally require chemical coatings; most brands either use PFAS-based water-repellent coating (water-repellent coating) finishes or non-fluorinated alternatives (polyurethane, TPU, or wax-based). Competitors like Helix and Casper disclose TPU or polyurethane explicitly but do not guarantee PFAS-free formulations. Coop's refusal to specify puts it below transparent mid-tier brands and on par with budget retailers that offer no disclosure whatsoever.
If you buy it
Wash the protector at least monthly in cool to warm water (not hot, which accelerates plasticizer leaching) and air-dry or tumble-dry on low; never dry-clean. Do not place directly against sensitive skin without an additional cotton barrier. Replace after 3-5 years or if the coating becomes sticky, flaking, or emits a chemical odor, as degradation increases leaching risk. Store in a cool, dry place away from direct sunlight to slow aging of the polymer.
