We just executed the exchange of a memory foam mattress we'd chosen for our "new" master bedroom. The overwhelming stench it emitted came from its formaldehyde content. It screams, "Carcinogen!" Formaldehyde. Can you imagine?
Needless to say, we were not aware of the sickening component till after I developed pounding headaches and nausea as a result of sleeping on it for a few nights. We'd concentrated on reviews regarding comfort... no merchant revealed feedback about its literal dark side. Once there's a problem, deeper research leads to the discovery that strong gasses need to escape the foam. "Escape to where?" you ask. Here is the recommended procedure, upon acquisition of this beast.
Freakin' brutal.
Freakin' brutal.
In my opinion, it would never be free of contaminants... period.
Good riddance. Please be warned.
