The Lullaby Earth Breathe Safe Breathable Crib Mattress delivers more airflow than traditional non-breathable crib mattresses — independently tested and proven — without sacrificing the waterproof protection and hygienic design that parents depend on from day one. It’s the breathable mattress our team reaches for when families want practical safety backed by real engineering.
How Breathe Safe Breathability Actually Works
The removable cover is constructed from a 3-dimensional fabric structure that allows air to flow freely through the material and underneath the baby, creating 360° of air circulation around the sleep surface. Because air passes through the fabric’s 3D channels rather than around the edges, babies can breathe directly through it — a meaningful distinction from mattresses that only claim side-venting. The cover’s waterproof backing protects the mattress core from messes and is fully machine washable and dryer safe.
Dual-Sided Firmness for Infant & Toddler Sleep
The firmer infant side meets CPSC and pediatrician recommendations for newborn sleep safety, while the softer toddler side provides the right amount of cushion as your child grows. The WaveSupport™ core keeps the sleep surface firm and flat at both stages, with reinforced edges that stand up to the bouncing and pulling of an active toddler.
Lightweight, Chemical-Free & Made in the USA
At just 7 lbs with square corners for a snug crib fit (approx. 27¼” × 51⅞” × 6”), the Breathe Safe is easy to handle and built from food-grade PE waterproofing and recycled polyester fiber fill. It passes all federal flammability requirements without any flame retardant chemicals or barriers, and is free of vinyl, PVC, polyurethane foam, antimicrobials, perfluorinated compounds, and phthalates.
