Where these two actually differ
- We flag Volatile Organic Compound (VOC) off-gassing, Polyurethane foam degradation and particle shedding and Dust mite and mold colonization on the Casper and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the Casper is Polyurethane foam, cotton/polyester blend cover, which is most of the difference in these two grades.
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 →
