We've been mattress shopping for a month. Making a decision today.
It has been VERY difficult finding a natural mattress. As of July 1, all mattresses sold in the US will have to meet new fire standards. (Bringing the code "up" to California standards, is one way I've heard it mentioned several times.)
Basically, they'll be adding more chemicals as fire retardants to mattresses. Most of the mattresses in the conventional mattress stores already meet these standards. I think it is a standard on which I do not want to be sleeping.
I had a conversation this morning from a woman who works at A Natural Home. We tried out their mattresses at their local store. The mattresses (and their other furniture) are made here in Central Ohio, not 15 miles from us.

The mattresses they sell
are fire retardant to current standards, as they have wool in them; wool is a natural fire retardant. As of July 1, they will have a physican on retainer to write prescriptions for people who want to buy one of their mattresses. They will charge an extra $25 for this service. The mattresses they sell will not meet the NEW standards (because they will remain chemical free). Many of the local (Ohio) mattress companies are going out of business because they cannot afford (or refuse) to meet these new standards.
If you need to buy a new mattress, I'd do it SOON. Or, investigate "all natural" mattresses. (The woman also had some stories to tell about places claiming organic or natural, but these terms referred only to the top piece of fabric, for example, not the entire mattress.) It is going to be VERY hard to purchase something that is chemical free. (I am not even concerned about the organic piece at this point - just give me something without chemical fire retardants woven into it!)
You should look for: wool (the natural fire retardant) and cotton. Also, if you are interested in foam, look for "natural latex," as opposed to any other type of foam.
The company also sells a LOT of baby mattresses. They can custom make any size of baby mattress. She wanted us to go over to the place (an old house) where they make the mattresses - apparently they were making baby mattresses today. There are about 5 Amish families who work for them. There is one family who does basically all the mattresses. We will probably get a crib or toddler bed mattress from them.
