Organic crib mattresses are made with non-toxic materials instead of conventional and chemically treated materials. Your newborn spends a good portion of they day sleeping, so it is important to ensure a crib mattress is as pure as your little one. A typical crib mattress is made with many chemicals that have been linked to childhood health problems. Organic crib mattresses from Naturepedic and Ecobaby do no contain fire retardants, plasticizers, and other chemicals found in the foam and vinyl cover of a traditional mattress.
