PFAS score
Waterproof Inc. · Mattress Protectors
Mainstays Cooling Waterproof Fitted Mattress Protector
Skip until the brand discloses its waterproof chemistry, mattress protectors often use PFAS-based water-repellent coating, and silence is a red flag.
Mainstays and Waterproof Inc. provide no public information about the waterproof coating's chemistry or PFAS content. Mattress protectors typically rely on water-repellent coating (water-repellent coating) finishes, which historically use fluorinated compounds.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
