PFAS in Mattress Protectors: Which Brands Grade Best and Worst
Mattress protectors are a practical defense against spills, allergens, and dust mites—but many rely on chemical treatments to achieve waterproofing, and those treatments often involve per- and polyfluoroalkyl substances (PFAS). Based on available materials and public disclosures, most mainstream mattress protectors score poorly on PFAS concern. However, Organic Textiles Organic Mattress Protector 2-Pack stands out with a grade D (65/100 safety), representing our model-based estimate from materials and public disclosure—not a lab test. While a D grade indicates lower concern relative to peers, it reflects the reality that many protective fabrics rely on chemical finishes; no mattress protector in our current database shows evidence of PFAS-free construction verified by independent testing.
The troubling news: brands like Tempur-Pedic TEMPUR-Protect Mattress Protector (Twin Long) and Avocado Green Mattress Avocado Organic Waterproof Mattress Protector score F grades (30/100 safety), our lowest tier. Even products marketed as "organic" or "chemical-free" often employ water-resistant finishes that may contain PFAS or structurally similar compounds. This guide cuts through marketing claims and shows you which protectors raise fewer red flags—and which ones to avoid entirely.

The Best Performing: Organic Textiles Organic Mattress Protector 2-Pack (Grade D, 65/100)
Organic Textiles Organic Mattress Protector 2-Pack holds the highest grade in our current mattress protector database. Based on available materials and data, this product earns a D grade—our model-based estimate, not a lab test result. A D grade reflects lower concern relative to competitors, though it does not mean the product contains no PFAS or PFAS-like compounds.
Materials: The brand emphasizes organic construction, though detailed fiber sourcing and waterproofing mechanism disclosures are limited in public materials. The 2-pack format suggests a commitment to long-term protection (one in use, one laundering), which may reduce reliance on heavy chemical finishes if replacement cycles are shorter.
Brand Claims vs. Verified Data: Organic Textiles markets this as an "organic" protector. However, "organic" certification typically applies to fiber content (cotton, wool) and does not guarantee absence of waterproof treatments. No third-party lab testing data is cited in public sources reviewed. The claim is brand-stated; independent verification is not available.
Pros: Two-pack value; organic labeling suggests supply-chain oversight; moderate price point for organic positioning.
Cons: Limited transparency on waterproofing chemistry; no third-party test results published; "organic" label does not preclude PFAS-alternative coatings.
Mid-Tier Options: D-Grade Mattress Toppers (65/100)
Nine additional products score a D grade, including Sleepyhead Sleepyhead 3 Copper-Infused Memory Foam Mattress Topper, Brooklinen Down Alternative Mattress Topper, and Nectar Nectar Firmer Mattress Topper. These represent a meaningful distinction from F-graded waterproof membranes, though they occupy a gray zone in PFAS disclosure.
Why Toppers Often Score Better Than Encasements: Foam and synthetic-fill toppers rely on material density and fiber architecture rather than waterproof chemical coatings. Sleepyhead's Copper-Infused variant adds anti-microbial copper, which is distinct from PFAS chemistry. Conversely, encasements like Brooklinen Brooklyn Bedding Mattress Encasement, Twin (also a D grade) must achieve total waterproofing, a function often requiring chemical finishes.
Material Transparency Issues: Most D-grade toppers do not publicly disclose whether their water resistance stems from inherent material properties, coating, or both. Brands typically cite memory foam or down-alternative as the headline material but say little about finish treatments. This opacity is why even the "best" performers in this category merit only a D, not higher.
Worst Performers: F-Grade Waterproof Protectors (30–35/100)
Five products score F, the lowest tier: SafeRest Saferest Premium Hypoallergenic Waterproof Mattress Protector (35/100), Tempur-Pedic TEMPUR-Protect Mattress Protector (Twin Long) (30/100), and Avocado Green Mattress Avocado Organic Waterproof Mattress Protector (30/100).
SafeRest Premium (35/100): Marketed as "vinyl-free," which might suggest a PFAS-free alternative. However, vinyl-free does not equal PFAS-free; many waterproof membranes substitute polyurethane or polyester with PFAS or fluorinated finishes. SafeRest's public materials do not detail the specific waterproof agent used, leaving material composition opaque.
Tempur-Pedic TEMPUR-Protect (30/100): Tempur-Pedic is a premium mattress brand with limited public disclosure on protector chemistry. The waterproof layer is likely a proprietary membrane, but the brand provides no accessible information on PFAS content or alternatives. The low score reflects this opacity combined with the inherent concern of true waterproof barriers.
Avocado Green Organic Waterproof Protector (30/100): Avocado markets this as "organic," yet the waterproof component is never detailed. An organic mattress core does not mean the waterproof layer avoids PFAS. Avocado does not publish independent lab testing for PFAS. The "organic" label creates a false halo; the F grade corrects for this marketing gap.
What to Avoid: Red Flags in Mattress Protector Marketing
- Waterproof Claims Without Chemistry Disclosure: Any brand that touts waterproofing without explaining the mechanism—membrane type, coating material, or treatment—warrants suspicion. True transparency requires naming the waterproof agent (e.g., polyurethane, wax, ceramic, or PFAS-free polymer).
- "Organic" Labeling on Waterproof Products: Organic certification for cotton or wool fibers does not extend to waterproof coatings. Brands that emphasize organic fiber while staying silent on the water-resistant finish are conflating fiber safety with finish safety. Avocado Green Organic Waterproof Mattress Protector exemplifies this gap.
- "PFAS-Free" Claims Without Lab Proof: Brand-stated "PFAS-free" claims are marketing language unless backed by third-party lab reports. No mattress protector in our database shows published independent lab testing confirming PFAS absence. Beware the unsubstantiated claim.
- Vinyl-Free Marketing as a PFAS Proxy: "Vinyl-free" sounds like progress, but it is a narrow claim. Polyurethane, polyester, and other polymers can carry PFAS or fluorinated additives. Vinyl absence does not guarantee PFAS absence.
- Encasements Over Toppers: If PFAS concern is your primary driver, favor toppers (foam, fill, or quilted) over full encasements. Encasements must achieve 100% waterproofing, a barrier function nearly always requiring chemical assistance. Toppers offer partial protection without requiring a sealed membrane.
Our Pick: A Pragmatic Approach
Based on available materials and data, Organic Textiles Organic Mattress Protector 2-Pack represents the lowest-concern choice in the current marketplace. The D grade (65/100 safety) is our model-based estimate from materials and public disclosure, not lab certainty. It does not mean the product contains no PFAS; it means relative transparency and a non-waterproof-membrane design position it ahead of F-graded alternatives.
However, if you need waterproofing—for example, to protect against bed-wetting or incontinence—no mattress protector in our database shows evidence of PFAS-free construction verified by independent testing. Your choices then become a trade-off: accept a D-grade topper for partial protection, or select an F-grade encasement for full waterproofing while acknowledging the higher PFAS concern based on available data.

Frequently Asked Questions
1. Does "waterproof" automatically mean PFAS is present in a mattress protector?
Not automatically, but the probability is high based on industry practice. Waterproofing relies on a barrier function, most commonly achieved via polymer coatings or membranes. Many of these employ PFAS or chemically similar fluorinated compounds for durability and water repellency. Some brands experiment with wax, ceramic, or silicone alternatives, but these are less common and rarely disclosed without a specific sustainability claim. If a brand claims waterproofing without naming the mechanism, assume a conventional polymer finish until proven otherwise.
2. Is an "organic" mattress protector free of PFAS?
Not necessarily. "Organic" certification applies to fiber sourcing (e.g., organic cotton, organic wool) and farming practices; it does not regulate waterproof treatments or chemical finishes. Avocado Green's organic waterproof protector is a clear example. The organic label creates a halo effect but provides no assurance about the waterproof layer. Always ask: Is the finish treated? If yes, with what? Brands silent on this point are not being transparent, regardless of fiber origin.
3. If I'm concerned about PFAS in mattress protectors, what's my safest option?
Based on available materials and data, your safest option is a topper (foam, synthetic fill, or quilted) rather than an encasement. Toppers do not require 100% waterproofing, so they may avoid the chemical coatings needed for sealed membranes. Organic Textiles Organic Mattress Protector 2-Pack is our current highest-graded option (D, 65/100). However, a D grade remains a relative measure, not a lab-verified finding of PFAS absence. If you need true waterproofing, current market transparency does not support a "lower concern" choice; all waterproof membranes raise concern based on available data. In that case, consult a physician about alternatives (e.g., absorbent underpads, mattress covers you can wash frequently) to reduce contact time with any chemical-treated surface.
