Keep-a-bed Waterproof Mattress Cover for RVs & Campers, Are They Non-Toxic?
Skip until coating chemistry is disclosed.
Mattress cover marketed as waterproof without information about coating chemistry. Most waterproof textiles use PFAS-based water-repellent coating finishes; PFAS risk is substantial and unquantified.

Are Keep-a-bed Waterproof Mattress Campers non-toxic? What it is made of
The Keep-a-bed cover is polyester or poly-blend fabric with an unspecified waterproof coating. Waterproofing in budget mattress protectors historically relies on Teflon-type coating (Teflon) or other fluorinated polymers, which introduce PFAS and fume risk when heated or abraded. The brand has not publicly disclosed the coating chemistry, making it impossible to rule out legacy fluorinated water repellents. Polyester itself is stable, but the coating is the critical unknown.
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.
Teflon-type coating/Teflon-family coating fume risk (thermal decomposition)
If the waterproof coating contains Teflon-type coating or other fluorinated polymers (not disclosed), exposure to heat above 300°F can release toxic fumes. RV mattress covers may experience high localized heat in sunny climates or near heating vents; unconfirmed coating type makes risk assessment impossible.
PFAS
Waterproof coatings in budget mattress protectors commonly use PFC (perfluorinated compound) chemistry. The brand's silence on formulation and low safety grade (30/100) suggest fluorinated repellents are probable. PFAS can leach into skin contact and dust, accumulating over time.
Source, ATSDR ↗Coating degradation and microplastic shedding
Polyester-based fabric protectors with applied coatings shed microparticles as the coating breaks down under friction, moisture, and UV exposure. No specific data on Keep-a-bed exists, but this is a known issue in the category, particularly in humid RV environments.
VOC off-gassing from coating or adhesive
Unspecified waterproof coatings and adhesives used to bond coating to polyester may release volatile organic compounds (solvents, plasticizers) in the first weeks after purchase. Off-gassing intensity depends on coating chemistry and is unknown for this product.
Mold and bacterial growth if moisture is trapped
Waterproof coatings create a moisture barrier; if the cover is not properly ventilated or dried after laundering, the enclosed polyester and mattress interior become a humid microenvironment. The brand does not specify breathability, raising risk of mold or mildew growth in damp RV storage.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand is a budget pet and home textile brand with no published safety certifications (Oeko-Tex, GOTS, etc.) or PFAS commitment statements in publicly available materials. The company does not appear to maintain transparency on coating formulations across its product line. No recalls related to chemical hazards have been documented, but absence of disclosure is a red flag in an industry where fluorinated water repellents remain common in low-cost protectors.
How it compares in its category
Most RV and camper mattress protectors at this price point use similar unspecified coatings. Premium alternatives (Waterproof Mattress Protectors from brands with OEKO-TEX or PFC-free certifications) explicitly state coating type and are typically 30-50% more expensive. Budget-tier protectors like this one rarely disclose coating chemistry, making direct comparison difficult. If PFAS-free protection is a priority, certified alternatives exist but cost more.
If you buy it
Contact directly to request a specification sheet or safety data sheet for the waterproof coating before purchase. Do not expose the cover to high heat (dryers, direct sun for extended periods) until coating is confirmed to have lower concern for off-gassing or degradation, as unknown polymers may release compounds or degrade. Wash in cool water and air-dry to minimize coating stress. Plan to replace every 2-3 years if used in humid RV environments, as waterproof coatings degrade over time and may fail in ways that are difficult to detect.
