Coop Home Goods Ultra Tech Waterproof Mattress Protector
Avoid until the brand discloses waterproof treatment chemistry.
The brand does not publicly disclose the specific chemistry of the 'Ultra Tech' waterproof coating. Waterproof textile treatments often rely on PFAS-based water-repellent coating finishes.

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.
Waterproof coating off-gassing and degradation
Polyurethane or PFAS-coated fabrics release volatile organic compounds (VOCs), especially when new or heated. This mattress protector is in direct contact with skin and lungs 8+ hours daily, making off-gassing exposure significant if ventilation is poor.
Polyurethane breakdown over time
Polyurethane coatings are known to degrade, crack, and shed microparticles when exposed to moisture, body heat, and washing cycles. This creates both inhalation and ingestion pathways for coating fragments.
Formaldehyde / VOCs
Polyester fabrics may contain formaldehyde-based resins used in finishing and wrinkle resistance. Coop Home Goods has not disclosed testing for formaldehyde content. Prolonged skin contact with formaldehyde-treated textiles can trigger dermatitis in sensitive individuals.
Source, ATSDR ↗Chemical leaching into sweat and skin
Coatings in direct contact with warm, damp skin (perspiration) create conditions favouring leaching of unreacted monomers and additives. The protector sits between the sleeper and mattress for prolonged periods, maximizing exposure.
Lack of third-party certification or testing disclosure
No OEKO-TEX, GOTS, or equivalent certification is listed for this product. This absence of accountability makes it impossible to verify absence of heavy metals, dyes, or restricted substances in the coating or base fabric.
The full breakdown
What it's made of and why it matters
This protector uses polyurethane or polyester as the base fabric with an unspecified waterproof coating. The coating is the critical unknown, most waterproof mattress protectors rely on either PFAS-based durable water repellents (water-repellent coating) or polyurethane membranes. Since Coop Home Goods has not publicly disclosed the chemistry, you cannot rule out legacy PFAS compounds like Teflon-type coating or newer alternatives. The base fabric itself poses lower direct risk, but the coating is where toxicity concerns concentrate.
The brand's record and disclosure
Coop Home Goods has not issued public statements on waterproof treatment chemistry, chemical certifications (such as OEKO-TEX or GOTS), or PFAS content testing. The brand markets sustainability and materials with lower concern but provides no third-party evidence or transparency on the specific water-repellent coating used in this product. This silence on a regulated substance class is itself a red flag in an industry where competitors increasingly disclose PFAS avoidance.
How it compares in its category
Most mass-market waterproof mattress protectors use legacy PFAS or polyurethane coatings; some brands (e.g., Helix, Purple) have begun disclosing non-PFAS alternatives or pursuing certifications. Coop Home Goods' lack of disclosure puts it below competitors who have made explicit commitments. The product sits in the mid-market price range where cost pressures often favour PFAS use, though this is not definitive without direct chemical testing.
If you buy it
Wash before first use in warm (not hot) water to remove loose coatings and off-gassing residues. Do not expose to high heat (dryer on low air-dry only) as polyurethane coatings can degrade and off-gas volatile organics. Replace every 5-7 years or if the waterproof layer cracks, peels, or becomes tacky. Before purchase, contact Coop Home Goods directly and ask for written confirmation of the waterproof coating type; a refusal or vague answer reinforces the skip recommendation.
