Where these two actually differ
- We flag Polyurethane off-gassing (VOCs), Waterproof barrier chemical composition (non-PFAS), Antimony in polyester and Barrier degradation over time on the Sleep Number and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the Sleep Number is Polyester/polyurethane mattress pad with waterproof barrier layer, 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 Sleep Number 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 →
