Platinum Zip-Off Top Mattress Protector vs Vintage Linen Bed Cover: which is safer?

Where these two actually differ

• We flag PFAS in waterproof coating, Flame retardants (brominated or phosphorus-based), Volatile organic compounds (VOCs) from coating off-gassing and Coating degradation and microparticle shedding on the AllerEase 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 AllerEase.
• The AllerEase is Polyester blend with unspecified waterproof/stain-resistant coating 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 AllerEase grade, at 42% confidence against 82%, because it discloses less.
