Going back because of horrendous smell

We have had this mattress for 2 weeks, after sleeping on it first night I woke up with sore throat and the smell was horrible. I aired it out for a day. Put mattress pad on and sheets, smell still horrible. I'm getting sicker. Washed everything on mattress again and tried ia again. I now have an infection which I think is from the fumes. I am on a z-pack and the mattress is being exchanged. My eyes flared up as well which they always do when I have a certain type of foam under them. It's a shame they can't make a mattress that is comfy and doesn't smell. Don't buy this toxic mattress if you are at all sensitive to smells. Now my husband didn't even notice the smell.
