IKEA GRUSNARV Waterproof mattress protector
Skip until PFAS status is clarified.
Waterproof mattress protector lacks public disclosure of waterproofing chemistry from IKEA/Keet. Waterproof textiles represent high-risk category for PFAS-based water-repellent coating coatings.

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.
Phthalates
Polyurethane coatings may contain phthalate plasticizers unless explicitly stated otherwise. IKEA does not disclose plasticizer type for GRUSNARV. Direct skin contact (perspiration, body warmth) may increase migration risk over time.
Source, ATSDR ↗Coating degradation and leachable release
Waterproof coatings degrade under repeated washing, heat, and humidity. As the coating breaks down, trapped chemicals (unreacted monomers, additives) may leach into sweat or the underlying mattress foam, especially in high-moisture environments like bathrooms or humid climates.
Off-gassing from polyurethane or adhesives
Mattress protectors with polyurethane components commonly emit volatile organic compounds (VOCs) including toluene and methylene diphenyl diisocyanate (MDI) precursors for weeks after purchase. Ventilation reduces but does not eliminate this exposure.
PFAS
The coating technology is not specified. Fluorochemical-free waterproofing exists but is not confirmed here. Without disclosure, PFAS exposure cannot be ruled out and remains the primary safety concern flagged in the PFAS assessment.
Source, ATSDR ↗Formaldehyde / VOCs
Polyester or blended fabric components may contain formaldehyde-releasing resins used for wrinkle resistance or fabric stiffening. IKEA does not provide finishing chemical data for this product. Prolonged contact (nightly use) presents low but unquantified exposure risk.

What it's made of and why it matters
GRUSNARV is a polyurethane or polyester blend with a waterproof coating, but IKEA/Keet does not publicly specify the coating chemistry. Waterproof mattress protectors typically use polyurethane, acrylic, or polyester-based coatings; some rely on PFAS compounds (fluorochemicals) to achieve water resistance without breathability tradeoffs. Without ingredient disclosure, you cannot confirm whether the waterproofing involves PFAS, phthalates, or other synthetic additives.
The brand's record and disclosure
Keet is a IKEA-owned bedding brand with minimal public chemical disclosure for this product line. IKEA has faced scrutiny over PFAS use in water-repellent textiles but has not released category-specific PFAS commitments for mattress protectors. No third-party certifications (OEKO-TEX, GOTS, Cradle to Cradle) are documented for GRUSNARV. The brand's silence on waterproofing chemistry is a significant red flag in an industry where PFAS alternatives exist.
How it compares in its category
Most budget waterproof mattress protectors (IKEA price tier, under USD 50) lack detailed chemical disclosure. Premium certified alternatives (e.g., polyester with PFAS-free water-repellent treatments or polyurethane foam cores verified PFAS-free) typically cost 1.5x to 3x more and disclose coatings. GRUSNARV's opacity is typical for mass-market products but below the transparency standard of health-conscious or allergy-focused mattress protector brands.
If you buy it
Air out the protector for 24-48 hours before first use to reduce off-gassing from the waterproof coating. Avoid heat (hot water washing, direct dryer heat) as polyurethane coatings can degrade and release residual chemicals; use cold water and air dry. Replace if the waterproof layer peels, cracks, or flakes, as coating breakdown may accelerate leachable release. Inspect seams and edges annually for wear, as delamination can compromise waterproofing and expose underlying materials.
