Where these two actually differ
- We flag VOC off-gassing from polyurethane base and unspecified coating, Coating degradation and leaching over time, Formaldehyde-based finishes in polyester-polyurethane laminates and Phthalates in plasticizers (if coating contains PVC or legacy plasticizers) on the and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the is Polyester/polyurethane fabric with waterproof coating (unspecified chemistry), 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 →
