How to Choose a Crib Mattress

A baby mattress should be very firm, fit the crib tightly, and use materials that are easy to keep clean. Breathability, waterproofing, and safety certifications are more important than plush comfort for infants.

Common crib mattress types

Foam crib mattresses are lightweight and affordable. Innerspring crib mattresses are heavier and structured. Organic crib mattresses use materials like organic cotton, wool, or coconut coir for families who prioritize non-toxic construction.
