Where these two actually differ
- We flag Volatile organic compound (VOC) off-gassing, Microplastic shedding, Flame retardant additive unknowns and Moisture and mold accumulation in use on the Casper and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the Casper is polyfoam/polyurethane foam topper, 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 →
