We take extreme measures at the manufacturing facility to produce our beds in a manner that any odor that is created in the packaging process should dissipate within a very short period of time, a few hours, maybe 2 days maximum. We wash all of our foam after production with mineral water, and we add active charcoal to help absorb any odor that may be created in the manufacturing process.
Off-gases are associated from opening a brand new mattress that has been sealed in plastic. Typically the solution is simply letting the mattress air out, uncovered, for a day or two, even opening windows in a room will help. Also, placing a quality mattress pad on top of the new mattress is always a good idea, as it helps protect the mattress from any potential spills.
