Vegan Mattress vs Posturepedic Plus Hybrid Norman II Mattress: which is safer?

Where these two actually differ

• We flag Heavy metal accumulation in natural latex and Latex allergy sensitization on the Avocado and not on the Sealy.
• We flag Volatile organic compounds (VOCs) from polyurethane foam, Flame retardant chemicals (unspecified type and location), Synthetic cover fabric degradation and shedding and Moisture and dust mite colonization if poorly maintained on the Sealy and not on the Avocado.
• The Avocado is organic cotton, natural latex, coconut coir, recycled steel coils where the Sealy is foam core, fabric cover (composition unspecified by brand), which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Avocado is the one to buy.
• We are less certain about the Sealy grade, at 55% confidence against 82%, because it discloses less.
