Ok seriously for the best night sleep I have had in years.  I read several reviews that complained about how firm it is, yes it is very firm, but that is what I ordered.  Yes, there is an odor to the mattress, however that dissipated in about 24 hours. 

I received my mattress on Tuesday opened it up on to my bed and let it “puff” up.  I added no bedding and I did not sleep on it Tuesday night.  Wednesday late afternoon I smelled it because of the complaints about the smell, which I smelled Tuesday upon opening and Wednesday morning, as stated the smell had dissipated.  If you are looking for a FIRM mattress at a great cost, stop looking you have found it.
