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 Polyurethane foam off-gassing (VOC/formaldehyde releasers), Formaldehyde resins in fabric finish (cover), Dust mite and allergen accumulation and Flame retardant additives (if present in foam) on the Sealy and not on the Avocado.
- The Avocado is organic cotton, natural latex, coconut coir, recycled steel coils where the Sealy is Steel coils, polyurethane foam, cotton/poly blend cover, 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.
