Buying Guide

Firmness and safety

Choose a firm, flat surface designed for infants; mattresses labeled for crib and toddler use reduce suffocation and SIDS risk when paired with a fitted sheet

Certifications to prioritize

Look for independent certifications such as GREENGUARD Gold or OEKO‑TEX that indicate low chemical emissions and safer materials

Waterproofing and covers

A waterproof or water-resistant cover helps protect the mattress from spills and accidents; removable or fitted waterproof pads can simplify cleaning

Material and breathability

Consider materials like innerspring, foam, or organic cotton pads and check for airflow or breathable designs to help regulate temperature

Thickness and fit

Confirm mattress thickness and crib dimensions match (standard 28x52 in for many cribs) so there is minimal gap between mattress and crib sides
