Your newborn's sleep schedule depends entirely on the stability of their sleeping surface. The Milliard 2022 Edition mattress solves the common problem of outgrowing a nursery setup by utilizing clever flip technology.

It fits standard cribs perfectly, making it a seamless transition from infancy through the toddler years.

The triple-layer construction doesn't just offer support, but also actively manages heat through open-cell technology, preventing that uncomfortable overheating during long naps.
