I know this post is old but I too am interested if anyone has info on this topic. I'd like something eco friendly and perhaps something more simple. Maybe something designed more for a platform bed as well.
My husband and I have been researching both Naturepedic and PureRest mattresses. Both sell organic mattresses made of a either organic wool, organic cotton, or natural latex rubber. The mattresses do not have flame retardants (these materials are naturally flame resistant) formeldahyde or other harmful chemicals.
We just haven't decided yet because its such a huge purchase that its a little stressful!
I have also bought the mattresses from one of the website which deals with all such items.. Its totallly eco friendly and you can get it from anywhere.. There are so many shops which keep such stuff.. I was wondering to know where do you live?
