3D SafeSleep™ Technology
The soft, raised patented Pebble design increases the airflow around your baby, optimizing the amount of oxygen your baby gets throughout the night.
Nanosphere technology allows liquid to bead on the surface of the fabric, while eucalyptus lyocell contributes to a moisture-wicking environment that regulates your baby's body temperature, giving them a comfortable night's sleep.
Free of Plastic
There's a reason we tell our kids not to put plastic over their heads - it's not breathable. Our crib mattresses are free of impermeable, waterproof plastic and polymers that can grow mold.
We proudly use natural, biodegradable materials like cotton and eucalyptus lyocell in our covers.
