When bed bugs and nightmares aren't the biggest concerns

Reading this book recently, I was kind of surprised to find information about dangerous chemicals being used in mattresses- including crib mattresses. Some of these include polyvinyl chloride, phthalates, and chemical flame retardants. It is even suspected there is a link between these poisonous substances and SIDS. Considering how much time a baby is likely to spend in his or her crib, and how much more susceptible their tiny bodies are to toxins, I find myself once again really upset by the lack of regulation of dangerous chemicals in consumer products in the U.S.- especially those marketed for babies and children.
Thankfully, a few companies are offering organic mattresses- my favorite so far is Naturepedic. We're planning to buy one for our little guy's crib.
Here are a few articles about the dangers of chemicals in crib mattresses:
