I was looking at chairs and it says:

Our long lasting seat and back fabric is
made of Du Pont Teflon protected
Marquesa Lana Olefin, designed to resist
pilling, fading, punctures or moisture
while meeting the flame retardant stan-
dards of California Technical Bulletin
#117 (Section E).

I google the flame retardant standards and it only says how to test.  Nobody ever tells you what they put in the fabric or foam to make it flame retardant.  Is there anyway to find out?  I will email the company, but they never tell you and they never know.  I can't find an organic chair (that is what you said to look for in a mattress).

Also how do we know which foams have fire retardants in them when we buy them NOT in mattresses?  I assume they are not doing this to latex layers.  I did read they do treat cores somewhere.  This is just too confusing.  I don't want chemicals.
