Serta Cool Nites Zippered Waterproof Mattress Encasements
Skip until Serta discloses waterproof treatment chemistry, PFAS risk unclear.
This mattress encasement uses an unspecified waterproof coating to achieve liquid barrier performance. Serta provides no public disclosure of whether the treatment contains PFAS or alternatives. Waterproof textiles commonly use PFAS-based water-repellent coating agents, making this a higher-concern product category without transparency.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
