Where these two actually differ
- We flag Waterproof coating composition (non-PFAS), Formaldehyde from finishing resins, Coating degradation and microparticle shed and Off-gassing in bed environment on the Four Seasons Essentials and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the Four Seasons Essentials is Bamboo-derived fabric with waterproof coating (unspecified), 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 Four Seasons Essentials 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 →
