SimplySoft Waterproof Jersey Knit Mattress Protector vs Vintage Linen Bed Cover: which is safer?

Where these two actually differ

• We flag Fluorochemical DWR and PFAS in waterproof coating, Microplastic shedding from polyester-blend jersey, Coating degradation and waterproofing loss and Allergen accumulation and mold growth on the Sealy 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 Sealy.
• The Sealy is Jersey knit with waterproof treatment (composition not disclosed) 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 Sealy grade, at 35% confidence against 82%, because it discloses less.
