Brand New Queen Mattress

We just bought this mattress a few days ago and put it in the garage to air out as when you first take it out it is foam, it expands and it has a smell. My boyfriend has come to discover that he is allergic to the scent in the mattress. It doesn’t bother me. I can’t smell anything from it as it has been airing out in our garage for days. We want to sell it asap as he feels really sick from what he can smell that I can not. Photos to show receipt - amount paid - when purchased - and the mattress also comes with a cover we purchased for it in the store.
