Avocado Organic Waterproof Mattress Protector
Avoid until Avocado discloses waterproof coating chemistry, since mattress protectors often use PFAS-based treatments.
Avocado labels this as organic but does not publicly disclose what chemical creates the waterproof barrier layer. Waterproof mattress protectors commonly use PFAS-based durability treatments unless explicitly stated otherwise, creating uncertainty.

Material
Organic cotton/poly blend with waterproof barrier coating (unspecified)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Formaldehyde / VOCs
Unidentified water-repellent coating coatings may release volatile organic compounds or formaldehyde resins, especially when new or heated. No test data public for this product; risk is heightened by direct nightly skin/respiratory contact during sleep.
Source: ATSDR ↗Coating degradation and microfiber shedding
As waterproof coatings age or are washed, they can flake or shed fine particles. If the coating contains PFAS, shedding increases household dust contamination; if formaldehyde-resin based, degradation may liberate trapped chemicals.
Formaldehyde / VOCs
Some waterproof coatings and finishing treatments use formaldehyde-based resins for durability. Avocado's silence on coating chemistry means this cannot be ruled out. Initial off-gassing is usually strongest in first weeks to months.
Source: ATSDR ↗Allergic reaction to undisclosed coating components
Individuals with sensitive skin or respiratory sensitivities may react to unidentified waterproof resin components, dyes, or residual solvents. Lack of ingredient transparency prevents pre-purchase risk assessment for vulnerable users.
What’s reassuring
Polyester antimony content (minor)
The polyester blend may contain trace antimony as a catalyst, but levels in finished textiles are typically too low to pose acute risk. Not a focus hazard for this product given coating is the primary concern.
The full breakdown
What it's made of and why it matters
This protector combines organic cotton and polyester with an unnamed waterproof barrier coating. The organic cotton itself carries no known chemical hazards and avoids synthetic pesticide residues. However, the waterproof durability-water-repellent (water-repellent coating) coating is the critical unknown: Avocado does not publicly disclose whether it uses PFAS-based or PFAS-free chemistry. Waterproof mattress protectors typically require a water-repellent coating finish, and the industry standard has historically been fluorinated compounds (PFAS), though alternatives exist.
The brand's record and disclosure
Avocado markets itself as an organic and eco-conscious brand, yet provides no transparency on the waterproof coating chemistry in this product despite prominently labeling the cotton as organic. The brand has not issued public statements on PFAS avoidance or use in mattress protectors. This silence is a red flag in a product category where coating chemistry directly contacts skin nightly and can shed into household dust. Avocado's organic claims do not extend to full supply-chain disclosure for ancillary components.
How it compares in its category
Most mainstream waterproof mattress protectors use PFAS-based water-repellent coating treatments, making Avocado typical in its opacity. Some competitors (e.g., Organic Textiles, Naturepedic) explicitly state PFAS-free or alternative waterproof technologies. Avocado's organic cotton base is a genuine advantage over fully synthetic protectors, but the coating secrecy negates marketing differentiation. Without disclosure, this sits in the middle of the category: safer material foundation than 100% polyurethane-backed protectors, but lagging behind transparent alternatives.
If you buy it
Wash before first use to remove any loose chemicals or manufacturing residues. Machine wash warm (not hot, which can degrade coatings) and air dry or low heat; high heat may compromise waterproof integrity and accelerate VOC release. Replace within 3-5 years or if waterproofing visibly fails (pooling liquid, seeping through to mattress). Store in a well-ventilated space to minimize any off-gassing of the coating into your sleeping microenvironment, particularly important given nightly skin contact.
