ASIN: B07C8G5ZRDModel: Breathe Safe 2-StageCategory: Crib Mattresses

Overview

Lullaby Earth builds the Breathe Safe as a two-sided crib mattress, with a firmer face for infants and a medium-firm face for toddlers. A patented wavesupport core gives strength at a light weight, and a removable cover with a waterproof layer wraps the outside.

Switching sides as a baby becomes a toddler is the reason to choose it, since one mattress covers both firmness needs. Passing flammability rules without added retardants matters to parents avoiding them. The listing is thin, though, with no weight, warranty or certification stated.

Who it's for

Nurseries with a standard size crib suit this mattress, and parents who plan to use one mattress into toddlerhood benefit most from the second side. Owners of mini cribs or travel cots need a different size.

Pros and cons

Pros
  • Firmer infant side, medium-firm toddler side
  • Removable cover with waterproof layer
  • Meets flammability rules without flame retardants
  • Lightweight wavesupport core
Cons
  • Mattress weight not listed
  • Polyester cover, not organic cotton
  • Size is approximate, so check crib fit
  • Few specs listed to compare

Performance notes

Firmness depends on which side faces up, so the infant stage relies on the firmer face being on top. The wavesupport core carries the load, and the three-dimensional cover structure lets air move near the surface while the waterproof layer protects the core.
