Where these two actually differ
- We flag Water-resistant coating degradation and off-gassing, Polyurethane durability and wear-related particle release and Bacterial or mold growth in coating if maintenance is poor on the Sheex and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the Sheex is Polyurethane or polyester blend with water-resistant 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 Sheex grade, at 45% 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 →
