Memory foam update

I have definitely determined with the help of my BioSET allergist that I am allergic to the memory foam mattress I paid $1500 for from Foam Creations in Albany, California. This mattress is 6" of natural latex (NaturaLux from, and 3" of memory foam from
Foamex ( What I bought is called "300-10." I have written to both companies to ask if they use PBDEs.

FYI, Polybrominated diphenyl ethers or PBDE, are a flame retardant. For years, manufacturers have used chemical additives to reduce the flammability of everyday items, from computer casings to carpet pads to foam cushions in chairs and couches. Some of the more widely used of these additives are polybrominated diphenyl ethers, or PBDEs. In lab tests with rodents, some PBDEs have been linked to problems in brain development and thyroid hormones. Most of these problems stem from pre-natal exposure and exposure soon after birth. The health effects appear to be permanent. PBDE levels in humans are about 10 to 100 times higher in the U.S., the world’s largest producer and consumer of PBDEs, than in Europe. Scientists say North American levels appear to be rising at an exponential rate, doubling every two to five years, while countries that have banned their use have seen levels decrease. U.S. levels of PBDEs are rising. Studies have found them in human blood, fat and breast milk. Breast-feeding appears to overcome some of the effects of harmful chemicals and remains the healthiest way to feed babies.

I went to the store once again to complain about the smell in the mattress that would not go away (I have waited six months) and was told by the owner that over the years he's been selling foam (which is quite a few) that state regulations have slowly mandated that all mattresses be treated with flame retardants. In days of olde, he said, you had a choice of "F" grade (flame retardant) or not. All I know is that I feel very bad when I wake up in the morning, and the smell is pervading the whole bedroom, even though I have been opening the doors and windows all day long for the last six months. I suspect that the latex mattress does not have PBDE or other flame retardant, because it is less flammable and claims to be all natural. Since there is, unfortunately, no return policy on the mattresses from Foam Creations, I will be removing the upper 3" of memory foam to see how that improves things. I will post the replies to my emails to the manufacturers if and when I receive them.
