Beautyrest 300 Thread Count Mattress Protector
Skip until Beautyrest discloses coating chemistry or obtains PFAS-free certification.
Beautyrest's proprietary waterproof and stain-resistant finish remains a mystery, despite PFAS being the historical standard for such textile treatments.

Is Beautyrest 300 Thread Count Mattress non-toxic? What it is made of
This protector combines polyester and cotton with a proprietary waterproof and stain-resistant coating whose chemical composition Beautyrest does not publicly disclose. Polyester textile itself may contain antimony (a catalyst used in polyester production) at trace levels, though exposure from a mattress protector is minimal. The waterproof coating is the primary concern, such coatings commonly rely on fluorochemicals (PFAS), silicones, or polyurethane-based formulations, each with different off-gassing and durability profiles. Without transparency on this coating chemistry, the true hazard profile cannot be fully assessed.
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.
Flame retardants
Mattress protectors sold in the US are subject to federal flammability standards (16 CFR 1633), which may be met via chemical flame retardants, fiber selection, or physical barriers. Beautyrest does not publicly specify which approach is used for this product, so the presence and type of flame retardants are unknown.
Source, EPA ↗Volatile organic compounds (VOC) from waterproof coating
Coating degradation and microplastic release
Repeated washing, heat exposure, and physical flexing can cause waterproof coatings to crack or shed microparticles. Polyester fibers themselves can shed microfibers; degraded coating accelerates this process. No specific data on this product's coating durability is publicly available.
Formaldehyde / VOCs
Cotton components in blended textiles may be treated with formaldehyde-based cross-linking resins to improve wrinkle resistance and durability. Beautyrest does not disclose use of such finishes; formaldehyde off-gassing from textiles typically decreases substantially after first wash.
Source, ATSDR ↗What’s reassuring
Antimony residue in polyester fiber
Antimony is used as a catalyst in polyester production and may be present at trace levels in the fiber matrix. Migration from a mattress protector into bedding or skin contact is not established as a significant risk at typical exposure levels, and no specific contamination reports for Beautyrest protectors are on record.
The full breakdown
The brand's record and disclosure
Beautyrest (owned by Simmons Bedding Company) does not publicly disclose the chemical composition of its waterproof mattress protector coatings or provide PFAS-free certifications. The brand has not published third-party testing results for flame retardants, VOC emissions, or coating leachables in available consumer-facing materials. No major recalls or safety controversies specific to this product line are on record, but the lack of proactive disclosure is typical of the broader mattress and bedding industry, which has historically resisted transparency on treatment chemicals.
How it compares in its category
Mattress protectors in this price and thread-count range (300 TC) typically use polyester-dominant blends with waterproof coatings; Beautyrest's approach is industry-standard rather than differentiated. Some competitors (e.g., Naturepedic, Avocado) offer explicitly PFAS-free or certified organic alternatives at higher price points. Budget protectors often use similar undisclosed coatings; premium brands more frequently publish certifications (OEKO-TEX, GreenGuard, GOTS). Beautyrest occupies the middle market where transparency is inconsistent across the category.
If you buy it
Air out the protector in sunlight or a well-ventilated room for 24-48 hours before first use to allow initial off-gassing of coating volatiles. Machine wash in cool water (do not bleach) and tumble dry on low heat to avoid damaging the coating and triggering additional VOC release. Replace if the waterproof layer begins to crack, peel, or deteriorate visibly, as this can expose the underlying fiber and reduce barrier function. Avoid exposing the protector to prolonged heat (above 60 degrees Celsius / 140 degrees Fahrenheit) or harsh solvents.
