Ultimate Cotton Mattress Protector vs Vintage Linen Bed Cover: which is safer?
Parachute Vintage Linen Bed Cover is the clear pick. Allerease Ultimate Cotton Mattress Protector carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Waterproof coating chemical identity, Coating degradation and particle release and Allergen cross-reactivity from finish 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 cotton with waterproof/stain-resistant treatment (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.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
