Coop Home Goods Lulltra Waterproof Mattress Pad Protector Topper
Avoid until Coop discloses waterproof coating details.
Coop promotes this waterproof mattress topper without disclosing its waterproof treatment chemistry. Waterproof textiles commonly use PFAS-based water-repellent coating coatings, and Coop provides no ingredient transparency or third-party verification.

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
Waterproof backing on this product almost certainly contains fluorochemicals given industry standards, but Coop does not disclose. PFAS compounds can migrate to skin and household dust, with known bioaccumulation concerns.
Source, ATSDR ↗Coating degradation and microfiber shedding
Polyester blend fabrics with any waterproof coating degrade through washing and friction. Shed microfibers can enter washing machine discharge and potentially be inhaled during handling of worn pads.
Polyurethane off-gassing (if used as coating base)
If the waterproof backing uses polyurethane chemistry, new products may off-gas volatile organic compounds (VOCs) for 24-48 hours. No testing data is publicly available for this specific product.
Chemical leaching during use and washing
Direct skin contact on damp or sweating skin, combined with heat and detergent exposure during washing, can increase extraction of coating chemicals. Exact composition unknown, making risk quantification impossible.
What’s reassuring
Formaldehyde / VOCs
Polyester blends may contain formaldehyde-based finish resins, but no recalls or testing reports exist for this Coop product line. GOTS certification on some Coop products suggests some lines avoid this, but this waterproof line is not certified.
Source, ATSDR ↗The full breakdown
What it's made of and why it matters
This product combines a polyester-blend fabric top with an unspecified waterproof backing or coating. The coating chemistry is the critical unknown, waterproof barriers on mattress pads are typically either polyurethane-based, Teflon-type coating-based, or water-repellent coating (water-repellent coating) treatments using fluorochemicals. Coop does not disclose which technology is used here, leaving the PFAS risk unquantifiable. Polyester itself can shed microfibers under washing and friction, particularly if the protective backing degrades.
The brand's record and disclosure
Coop Home Goods maintains GOTS or similar organic certifications for some bedding products, but this waterproof protector line shows no detailed chemical ingredient disclosure or third-party waterproof coating testing. The company has not published a PFAS policy or public stance on fluorochemical avoidance in water-resistant products, despite industry movement toward transparency in this area. No major recalls or contamination incidents are on record for this specific product line.
How it compares in its category
Most mattress pad protectors in the mass market rely on polyurethane or fluorochemical coatings; alternatives using non-fluorinated water-repellent coating finishes or GOTS-certified organic cotton with natural wax barriers exist but are less common and pricier. Coop's product sits in the mid-market tier without competitive differentiation on chemical transparency. Brands like Naturepedic explicitly test for and disclose waterproof coating composition; Coop does not match this standard.
If you buy it
Contact Coop directly via their website to request the specific waterproof coating formulation before purchase. Use cool or warm water only (not hot) for washing to avoid coating degradation and microfiber release. Expect to replace the protector every 3-5 years depending on washing frequency, as all waterproof coatings degrade over time. Store dry and avoid tumble drying, which accelerates coating breakdown and potential chemical off-gassing.
