Organic Cotton Mattress Cover and Pad Protector vs Premium Smooth Mattress Protector: which is safer?

Where these two actually differ

• We flag Volatile organic compound (VOC) off-gassing from coating, Coating degradation and microparticle release, Waterproofing failure and mold/bacterial growth if poorly maintained and Unknown chemical composition and lack of third-party verification on the and not on the Avocado Green Mattress.
• The Avocado Green Mattress is organic cotton where the is unknown coating/waterproof treatment (likely polyurethane or fluoropolymer-based DWR finish), which is most of the difference in these two grades.
• The gap is 55 points, wide enough that this is not a close call, and the Avocado Green Mattress is the one to buy.
• We are less certain about the grade, at 35% confidence against 78%, because it discloses less.
