The Lullaby Earth Healthy Support Waterproof Crib Mattress Dual-Sided is engineered for families who want a chemically responsible, genuinely durable sleep surface that grows with their child. With patented waterproofing made without harmful chemicals, a firm WaveSupport™ core, and a dual-sided design that transitions from infant to toddler, it’s a mattress our team reaches for when parents want long-term value without compromise.
Patented Waterproofing Without the Harmful Chemicals
Lullaby Earth’s waterproofing is made from food-grade polyethylene — the same material used in food contact applications — with no vinyl, PVC, phthalates, or perfluorinated compounds anywhere in the construction. It wipes clean in seconds and holds up to the full range of nursery messes without degrading over time.
Dual-Sided Firmness That Transitions With Your Child
The firmer infant side meets CPSC and pediatrician recommendations for newborn sleep safety, while the cushion-firm toddler side provides the right amount of give as your child grows. Switching sides takes seconds — no tools, no hassle — and reinforced edges stand up to the bouncing and pulling that active toddlers are known for.
WaveSupport™ Core — Lightweight, Firm & Built to Last
At just 7 lbs, the WaveSupport™ core makes sheet changes genuinely manageable — a detail parents in our boutique consistently mention after the first week home. Square corners ensure a snug, secure fit in standard cribs at approximately 27¼” × 51⅞” × 6”, with no gaps along the sides.
No Flame Retardants, Superior Materials
The Healthy Support Dual-Sided passes all federal flammability requirements without any flame retardant chemicals or barriers. The mattress is made from food-grade polyethylene and polyester — free of polyurethane foam, formaldehyde, PFCs, pesticides, and GMOs — and backed by a lifetime limited warranty.
