Beauty Rest Chill Tech Mattress Protector vs Vintage Linen Bed Cover: which is safer?

Where these two actually differ

• We flag PFAS in water-resistant coating, Polyurethane or acrylic coating degradation and VOC release and Formaldehyde resins in polyester fabric on the Beautyrest 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 Beautyrest.
• The Beautyrest is Polyurethane or acrylic water-resistant coating on fabric (likely polyester) 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 Beautyrest grade, at 42% confidence against 82%, because it discloses less.
