GlacioTex Mattress Protector by Helix Twin
Avoid unless Helix commits to PFAS transparency or obtains third-party testing.
This mattress protector uses durability treatments to resist stains and moisture, a common PFAS application in textiles. Helix discloses no PFAS information, fluorochemical use, or testing, leaving legacy concern for treated textiles unresolved.

Material
Polyester blend with water-repellent coating (likely fluorinated)
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.
PFAS
water-repellent coating finishes on polyester textiles are predominantly fluorinated in the mattress-protector category. No lab testing for this specific Helix model is publicly available, but material type and industry practice indicate PFAS presence is probable. Degradation during washing and use is known to release coating residues.
Source: ATSDR ↗Formaldehyde / VOCs
Some water-repellent coating and other finish treatments may use formaldehyde-releasing resins for durability. No formaldehyde warning is published for this product. GlacioTex is designed for direct skin contact (on mattresses), so if formaldehyde is present, off-gassing would be minimal post-wash but cannot be fully ruled out without testing.
Source: ATSDR ↗Microplastic shedding
Polyester textiles shed microfibers with wear and washing, a documented environmental and potential inhalation concern. water-repellent coating coatings that degrade accelerate this shedding. GlacioTex, as a polyester blend subject to friction and laundering, will shed fibers over its lifetime; this is inherent to the material category, not unique to Helix.
What’s reassuring
Azo dyes
No public safety data or recalls indicate problematic azo-dye content in GlacioTex. Polyester blends in protective textiles are often dyed, but restricted azo dyes are regulated in EU and many brand standards. Without ingredient disclosure, this cannot be ruled out but is not a documented concern for Helix products.
Antimony catalyst in polyester
Polyester fibers may contain trace antimony (a catalyst used in polyester synthesis). Levels are typically very low and immobilized in the polymer matrix, so migration into skin or food is negligible. No specific safety alert exists for Helix polyester textiles. Risk is theoretical and far below that of intentional antimony additives (e.g., flame retardants).
The full breakdown
What it's made of and why it matters
GlacioTex is a polyester-blend fabric with a water-repellent coating (water-repellent coating) finish, almost certainly fluorinated given industry standard practice for mattress protectors. Polyester itself is stable and does not leach under normal use. However, the water-repellent coating, applied to resist liquids, is the material class most associated with PFAS contamination in textiles. water-repellent coating finishes degrade with washing and age, potentially releasing coating particles and chemicals into the environment and home.
The brand's record and disclosure
Helix has not published transparency reports on PFAS use in textiles, chemical inventories, or third-party testing results for this protector. The company is known for mattress innovation but has remained silent on per- and polyfluoroalkyl substance sourcing. No public recalls or safety violations are on record for this product. Without commitment to PFAS disclosure or independent certification (e.g., OEKO-TEX 100, GOTS), Helix's stance cannot be verified as precautionary.
How it compares in its category
Most mattress protectors use polyester with fluorinated water-repellent coating coatings; this is industry baseline. Some competitors (e.g., certified organic or PFAS-free alternatives) offer non-fluorinated water resistance via wax or silicone-based finishes, though these are less common and often more expensive. Helix's product is typical in formulation but without transparency, it does not stand out as a safer choice within the category. If PFAS content is a concern, actively seek brands with third-party testing or explicit PFAS-free certifications.
If you buy it
Wash before use and limit to cold water; hot water may accelerate water-repellent coating breakdown and shedding. Do not dry clean. Replace every 2-3 years or sooner if visible wear, pilling, or water-repellency loss occurs, as degraded coating increases particle release. Store away from direct sunlight and extreme humidity to slow aging. Consider pairing with a second, non-treated barrier layer (e.g., plain cotton sheet) between mattress and protector if you wish to minimize exposure to coating degradation products.
