Where these two actually differ
- We flag Waterproof coating off-gassing and degradation, Polyurethane breakdown over time, Formaldehyde or formaldehyde resins in base fabric and Chemical leaching into sweat and skin on the Coop Home Goods and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the Coop Home Goods is Polyurethane or polyester 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 Coop Home Goods 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 →
