LikelyPFAS in waterproof coating (graded separately but relevant context)
PossibleCoating degradation and microparticle shedding
PossibleFormaldehyde or other chemical finishes in textile base
Where these two actually differ
- We flag PFAS in waterproof coating (graded separately but relevant context), Coating degradation and microparticle shedding, Formaldehyde or other chemical finishes in textile base and Allergy or skin sensitivity to coating chemicals on the My Green Mattress and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the My Green Mattress is Waterproof textile with unspecified coating/treatment, 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 My Green Mattress 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 →
