Sleep Outfitters Helix Cooling Mattress Protector vs Vintage Linen Bed Cover: which is safer?

Where these two actually differ

• We flag Waterproof coating composition (non-PFAS hazards), Antimony leaching from polyester, Microplastic shedding and Coating degradation and delamination on the Helix 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 Helix.
• The Helix is Polyurethane or polyester blend with waterproof coating (composition 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 Helix grade, at 45% confidence against 82%, because it discloses less.
