pedic Total Protection Waterproof Mattress Pad vs Vintage Linen Bed Cover: which is safer?

Where these two actually differ

• We flag PFAS in waterproof coating, Polyurethane off-gassing and degradation, Microplastic shedding from coating and Bacterial or mold growth in waterproof layer on the Serta and not on the Parachute.
• We flag Azo dyes or heavy metal pigments, VOC off-gassing or odor and Mildew or mold growth if damp on the Parachute and not on the Serta.
• The Serta is Polyurethane or polyester base with waterproof coating (unspecified) where the Parachute is 100% linen, no reported coating, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Parachute is the one to buy.
• We are less certain about the Serta grade, at 45% confidence against 82%, because it discloses less.
