In the Bay Area, my wife was also concerned about the brominated fire-retardants and found a manufacturer in Marin that use latex foam and wool toppers to make mattresses. We ordered one for us (custom dimensions for a European bed) and one for our daughter. We also had them make cushions for our couch: the frame is rattan so no stuffing or fabric, then we just put the old covers over the new cushions. They are all comfortable and free of chemicals. The downsides are they are expensive and heavy (takes 2 people to move the twin mattress). However, this was over 10 years ago, and I don't remember the name of the company.
