This MAMAZING Aerobase mini crib mattress is new and factory sealed, with only the outer box showing cosmetic damage from storage. The dual‑stage design provides a firm infant side and a softer toddler side, giving you long‑term use as your child grows. Its breathable construction helps promote airflow and temperature regulation, while the waterproof inner liner protects the core from spills and moisture.

The removable outer cover is machine‑washable for easy care, and the 38" × 24" sizing fits most mini and portable cribs. Ideal for parents wanting a safer, cleaner, and low‑maintenance sleep surface. Ships double‑boxed for added protection during transit.
