Buying Guide

Firmness for infant safety

Choose a mattress with a firm, flat sleeping surface to reduce SIDS risk and ensure proper support for newborns and young infants

Fit to your sleep surface

Measure your crib or bassinet interior and match dimensions—products here include full-size crib/toddler and several common bassinet sizes like 35x20, 32x18 and 32x16

Breathable and moisture-resistant covers

Prefer mattresses with breathable or waterproof covers to help manage humidity and make cleaning easier; many options list removable covers for laundering

Material considerations: foam vs gel memory foam

Standard foam provides firm support while gel memory foam offers contouring and cooling; choose based on your child’s comfort needs and bassinet/crib recommendations

Ease of cleaning

Look for machine-washable or removable covers and waterproof layers to simplify cleanup for diaper leaks and spills
