Waterproof Mattress Protector Waxed Linen Cover Default_cpc_85DC90A9FD6C4 vs Premium Mattress Topper: which is safer?

Where these two actually differ

• We flag Waterproof backing chemistry (undisclosed), Residual solvents from manufacturing, Coating degradation and leaching over time and Allergic reaction to wax or adhesives on the Brooklinen and not on the Helix.
• We flag Volatile Organic Compounds (VOC) off-gassing from polyurethane foam, Polyester cover degradation and microfiber shedding, Polyurethane foam degradation and chemical leaching with age and Water-resistant coating composition (undisclosed) on the Helix and not on the Brooklinen.
• The Brooklinen is Waxed linen cover with waterproof backing where the Helix is polyurethane foam, polyester cover, 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 Helix is the one to buy.
