Where these two actually differ
- We flag Formaldehyde resins (wrinkle-finish or sizing residues), Reactive azo dyes (color fastness agents) and Microfiber or particulate shedding on the Parachute and not on the Pottery Barn.
- We flag Azo dyes and colorant toxicity and Residual manufacturing odors and off-gassing on the Pottery Barn and not on the Parachute.
- The Parachute is 100% cotton percale (plain weave) where the Pottery Barn is 100% organic cotton percale weave, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric: 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 →
