The Gio mini crib with 2.75-Inch mattress by Delta Children works perfectly in smaller nurseries or as a spare crib at Grandma and Grandpa's house. This versatile mini crib includes a comfy and water-resistant mattress and serves as the perfect space-saving alternative to a full-size crib. The Gio mini crib is the ideal choice for a modern nursery with its clean lines and compact design that features two adjustable mattress positions that allow you to lower the mattress height as baby grows. Delta Children was founded around the idea of making safe, high-quality cribs affordable for all families. That's why all Delta Children cribs are JPMA certified, and are tested above and beyond industry standards.
