Coop Home Goods Ultra-Tech Waterproof Mattress Protector Full, Smooth Top Mattress Pad, Waterproof Cover, Up to 18 Inches Deep, Machine Washable, Nois
Avoid until Coop reveals waterproof coating details.
Coop does not publicly explain the waterproofing treatment on this mattress protector. Waterproof pads commonly use PFAS-based water-repellent coating coatings, though non-PFAS alternatives exist, making PFAS presence impossible to rule out without disclosure.

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 backings commonly use PFAS-based fluorochemicals. Coop's silence on coating composition means you cannot rule out this hazard; it may shed into mattress and bedding over years of use.
Source, ATSDR ↗Polyurethane backing degradation and off-gassing
Polyurethane coatings can release volatile organic compounds (VOCs) especially if new or if exposed to heat/humidity. Early odor is normal but should fade; persistent chemical smell suggests degradation or solvents.
Microplastic shedding during washing
Polyester sheds microfibers into laundry water during machine washing. Risk is unavoidable with synthetic fabrics, but washing in cold water and using a microfiber filter bag reduces release.
Coating adhesion loss and leaching into fabric
Waterproof backings degrade with time and thermal cycling (washing, sweat, humidity). As backing breaks down, any chemicals in the coating can migrate into the polyester layer and contact skin and mattress.
What’s reassuring
Flame retardants
Coop does not specify whether polyester fabric is treated with flame retardants; current disclosure is too vague to assess. Untreated polyester poses no known hazard.

What it's made of and why it matters
This protector uses polyester fabric bonded to a polyurethane waterproof backing, but Coop does not specify whether the water-resistance treatment involves PFAS-containing Teflon-family coating (like Teflon) or non-fluorinated urethane coatings alone. Polyester itself is chemically stable; the concern centers entirely on the backing. Polyurethane backing without Teflon-family coating treatment presents lower chemical hazard concern, but fluorinated alternatives introduce persistent toxins that shed into mattresses and accumulate in your home.
The brand's record and disclosure
Coop Home Goods has not publicly disclosed waterproof coating chemistry or committed to PFAS-free standards. The company does not list third-party certifications (OEKO-TEX, GOTS, or similar) that would rule out fluorochemicals. Their silence on this common ingredient in mattress protectors is a red flag in a market where competitors increasingly advertise PFAS-free alternatives.
How it compares in its category
Many competing mattress protectors now explicitly claim PFAS-free, non-fluorinated waterproof coatings (e.g., polyurethane-only or wax-based backings). Coop's lack of transparency places this product in the riskier half of the category. Budget protectors often hide coating details the same way; premium options tend to disclose openly because it is a selling point.
If you buy it
Machine wash in cool water (hot water can degrade polyurethane backing and accelerate any coating shedding); air dry fully before use. Do not dry clean or expose to direct sunlight for extended periods, as UV degrades waterproof layers. Replace every 3-5 years regardless, as backing degrades with age and use. Contact Coop directly before purchase to request written confirmation that the waterproof treatment is PFAS-free; if they cannot confirm, consider switching brands.
