Organic Cotton Mattress Cover and Pad Protector vs Organic Cotton Waterproof Mattress Protector | White | Size Twin, Cotton/Polyester: which is safer?

Where these two actually differ

• We flag Fluorinated compounds (PFAS) in waterproof coating, Formaldehyde resins or durable-press finishes on cotton-polyester blend, Azo dyes or non-reactive dyes in fabric coloring and Polyurethane or other polymer film leaching from waterproof backing on the and not on the Avocado Green Mattress.
• The Avocado Green Mattress is organic cotton where the is Cotton/polyester blend with waterproof coating (type 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 grade, at 45% confidence against 78%, because it discloses less.
