Where these two actually differ
- We flag Fluorinated water repellent (DWR) coating chemistry unspecified, Volatile organic compounds (VOCs) off-gassing from coating, Coating degradation and leachate formation over time and Polyester or synthetic fiber skin allergen potential on the JML and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the JML is Textile with unspecified waterproof coating, 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 JML 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 →
