Waterproof Mattress Protector Bamboo Viscose Ultra Soft Leak-Proof Mattress Cover vs Vintage Linen Bed Cover: which is safer?

Where these two actually differ

• We flag Undisclosed waterproof coating composition, Coating degradation and skin contact and Off-gassing from synthetic backing on the 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 .
• The is Bamboo viscose with unspecified waterproof coating/backing 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 grade, at 42% confidence against 82%, because it discloses less.
