What Are the Size Requirements for a Portable Crib Mattress?

When selecting a mattress for a portable crib, it’s essential to adhere to specific size requirements to ensure safety and comfort for your baby. The mattress must fit snugly within the crib, preventing any gaps where a child could potentially become trapped.

2. Thickness: The thickness of the mattress is typically between 1 to 5 inches. A thinner mattress is often preferred for portability, but it should still provide adequate support to meet safety standards.
