Aller-Ease Allerease Maximum Allergy and Bedbug Waterproof Zippered Mattress Protector vs Vintage Linen Bed Cover: which is safer?

Where these two actually differ

• We flag VOC off-gassing from polyurethane backing, Polyester fiber shedding (microfiber/microplastics), Unknown waterproof coating leachates and Seam degradation and coating delamination 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/polyurethane blend 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 AllerEase grade, at 45% confidence against 82%, because it discloses less.
