Newton Baby crib mattress and toddler bed in white, breathable, washable and 100% recyclable.
A crib mattress is one of the most safety-critical nursery buys, and firmness comes first. Infants need a firm, flat surface that does not conform to the head, so look for a mattress rated firm for babies, a snug fit with no more than two-finger gaps around the edges, and a waterproof or easily wiped cover. GREENGUARD Gold or CertiPUR-US certifications signal lower emissions, and some dual-sided models offer a firmer infant side and a softer toddler side. Crib mattresses suit every crib and mini-crib setup, and a dual-stage option stretches value into the toddler years. A practical tip is to match the mattress precisely to your crib's dimensions, use only a fitted sheet with nothing else in the crib, and replace any mattress that is sagging, secondhand of unknown history, or no longer firm, since a proper firm fit is central to safe infant sleep.
