I'm trying to be greener in my choices and one thing that I am really anal about is the crib mattress. I bought an organic crib mattress from www.daxstores.com. I also bought a wool pad to put on the mattress for catching leaks. They are more expensive than normal ones, but to me, it's worth it. We went with a cheaper crib from IKEA that had a good rating from Consumer Reports to offset the cost of the mattress. I read a book called Raising Baby Green by Alan Greene, M.D. and he talks about all the different toxic chemicals that are used in regular crib mattresses.
Here is an article about the different chemicals to be concerned about.
Here is an article that talks about basic crib safety as far as firmness, etc.
