Avocado's dual-sided crib mattress is ingeniously crafted to provide healthy, supportive sleep even as your growing child's needs change. On one side, the mattress has a firmness that's ideal for newborns through age 1; flip it over, and the mattress has a little more give and plushness, all the better to support toddlers as they move around in the night. It's all crafted with organic materials, from the coconut husk and latex core to the soft cotton cover.
