Waterproof Memory Foam Pet Bed vs West Paw Heyday Dog Bed: which is safer?

Where these two actually differ

• We flag Waterproof coating degradation and leachables, Memory foam off-gassing (VOC / formaldehyde releasers), Microfiber or polyester filling shedding and PFAS in waterproof backing on the Petmaker and not on the Heyday.
• We flag Microplastic shedding from microfiber and Seam integrity and fill degradation over time on the Heyday and not on the Petmaker.
• The Petmaker is Memory foam core with waterproof backing/coating (unspecified) where the Heyday is Polyester microfiber with recycled polyester fill, 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 Heyday is the one to buy.
• We are less certain about the Petmaker grade, at 42% confidence against 82%, because it discloses less.
