While the memory foam that comes from the U.S. does not contain toxic ingredients such as formaldehyde or PBDE (polybrominated diphenyl ether), it can have somewhat of a new foam type of smell that can stay for a couple of days to a couple of weeks, depending on the foam manufacturer. While this smell does not seem to trigger allergies, it can initially be a bother for people who have sensitivity to smells. If you do experience this, here are some tips to help the smell go away more quickly:
• Air out the room and wash the sheets after the first couple of nights sleeping on the mattress.
• Sometimes a dish of vinegar on the night stand can help nullify the odors.
• An ozonator machine will rectify the situation very quickly.

However, if you are worried about the initial smell, there is a new technology memory foam called Biogreen®. This has been tested for V.O.C.’s (volatile organic compounds), the aromatic and often dangerous chemicals, by GreenGuard‘s stringent testing protocol, and it was found to have an unprecedented level that is approximately 13 times below Oeko-Tex, Certipur-US and GreenGuard‘s allowable total of V.O.C.’s required to achieve certification.
