Where these two actually differ

  • We flag Heavy metal accumulation in natural latex and Latex allergy sensitization on the Avocado and not on the Casper.
  • We flag Volatile organic compound (VOC) off-gassing from polyurethane foam, Polyester cover degradation and microfiber shedding and Mold and bacterial growth in absorbed moisture on the Casper and not on the Avocado.
  • The Avocado is organic cotton, natural latex, coconut coir, recycled steel coils where the Casper is polyurethane foam, polyester cover, which is most of the difference in these two grades.
  • The gap is 25 points, wide enough that this is not a close call, and the Avocado is the one to buy.

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 →
