LikelyCoating degradation and microparticle shedding over time
Where these two actually differ
- We flag Plasticizer and flame retardant leaching from polyurethane/TPU coating, Volatile organic compound (VOC) off-gassing from coating, Coating degradation and microparticle shedding over time and Thermal stability and heat-induced outgassing on the Coop Home Goods and not on the Avocado Green Mattress.
- The Avocado Green Mattress is organic cotton where the Coop Home Goods is Polyurethane or TPU 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 Coop Home Goods 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 →
