PossiblePFAS in waterproof coating (fluorinated compounds)

PossibleVolatilization of coating components (VOCs/off-gassing)
Where these two actually differ
- We flag PFAS in waterproof coating (fluorinated compounds), Coating degradation and microfiber release and Volatilization of coating components (VOCs/off-gassing) on the Downright and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the Downright is Polyester/cotton blend with waterproof coating (composition unspecified), which is most of the difference in these two grades.
- The gap is 55 points, wide enough that this is not a close call, and the Avocado Green Mattress is the one to buy.
- We are less certain about the Downright grade, at 35% confidence against 78%, because it discloses less.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
