The Lullaby Earth Healthy Support Waterproof Crib Mattress is engineered for safety and longevity. With patented waterproofing made without harmful chemicals, a firm WaveSupport™ core, and food-grade materials free of common allergens, it’s a mattress you can feel good about from day one.

Waterproof & easy to clean

Whether it’s spit-up, urine, or other messes, crib mattresses can get messy fast. Our patented waterproofing made without harmful chemicals is quick and easy to wipe clean.

Firm surface + edge support

Firmness is one of the most important safety features for your baby’s mattress. The CPSC recommends a firm, flat surface. Our mattress doesn’t sag, and reinforced edge support stands up to bouncing toddlers.

Lightweight + snug fit

Our patented WaveSupport™ core means bedding changes are easy — Lullaby Earth crib mattresses weigh only 7 lbs. Square corners ensure a snug, secure fit in standard cribs (approx. 27 1/4" x 51 5/8" x 6").

No flame retardants

We’re on a mission to provide the safest crib mattress — physically and chemically. This includes eliminating all flame retardant chemicals and other questionable chemicals.

Superior materials

Made from food-grade polyethylene and polyester — free of polyurethane foam, vinyl/PVC, formaldehyde, PFCs, pesticides, glues, and GMOs.

Made in the U.S.A.

The Lullaby Earth Healthy Support crib mattress is made right here in the U.S.A. and backed by a lifetime limited warranty.
