Vintage Linen Bed Cover vs Quilted Waterproof Bed Cover Ice Silk Summer Mat Mattress Protector Queen,Purple: which is safer?

Where these two actually differ

• 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 Purple.
• We flag Fluorinated water repellent (PFAS) in coating, Coating degradation and particle release, Formaldehyde in polyester finishing resins and Off-gassing from synthetic coating or adhesives on the Purple and not on the Parachute.
• The Parachute is 100% linen, no reported coating where the Purple is Ice Silk polyester/synthetic blend with waterproof coating (composition unspecified), 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 Purple grade, at 35% confidence against 82%, because it discloses less.
