LikelyPFAS (per-and polyfluoroalkyl substances) in water-repellent coating
ReportedCoating degradation and microplastic shedding
Where these two actually differ
- We flag PTFE/Fluoropolymer fume risk (thermal decomposition), PFAS (per-and polyfluoroalkyl substances) in water-repellent coating, Coating degradation and microplastic shedding and VOC off-gassing from coating or adhesive on the and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the is Polyester or poly blend with waterproof coating (type 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 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 →
