What do crib mattresses, cushioned car seats, and change tables all have in common? Yes, babies use them, but all of these items contain foam. This is problematic, since foam releases volatile organic compounds (VOCs) into the environment. VOCs come from the variety of resins, catalysts, solvents, and adhesives that are used in the manufacturing process, and they continue to volatilize long after production. Chronic exposures to low levels of VOCs have been linked in the past to infant allergies, asthma, and lung infections, but researchers have now done something different. They have measured the actual quantity of VOCs being emitted in a sleeping baby’s bedroom, and what they found is quite scary. Researchers from the University of Texas, led by environmental engineer Brandon Boor, analyzed 20 new and used crib mattresses made from either polyurethane foam or polyester foam. In a bedroom-sized chamber with a heated steel cylinder to imitate the heat released by a sleeping infant’s body (which would speed up the release of VOCs), they compared measurements of VOCs within the room (10 feet away from the crib) and within the infant’s breathing zone (2.5 cm/1 in above the mattress). According to Chemical & Engineering News, they found 30 different VOCs, including some that are classified as environmental pollutants and developmental disruptors. New mattresses released four times as many VOCs as old ones on average. But most importantly, they found that VOCs were significantly higher in the infant’s breathing zone than in the middle of the room, which is serious when you consider that many infants sleep 12-14 hours a day in close proximity to foam. The good news is that consumers don’t have to wait around for the industry to fix itself. There are alternative solutions that use latex, natural rubber, organic cotton, eucalyptus fibre, and/or coconut coir fillings, and are coated in organic cotton or wool, which are natural flame retardants.

If you can’t afford a natural mattress, one of the study’s coauthors recommends setting aside a new mattress for six months before bringing it into the house, giving it time to off-gas sufficiently.Check out our previous blog about OMI's certified-organic crib mattresses, Providing a Safe Sleeping Environment.
