Love the bed, but strong chemical sell

Overall my husband and I are pleased with the mattress however it is a lot harder than the one in the store. We were assured that it would soften up, but it has been three months and has hardly changed. I would also agree with the other reviewer that when the mattress was first delivered the smell of chemicals was overwhelming. I could not even go into the bedroom without being knocked over by the fumes from it. I refused to sleep on it until we aired it out, but we live in a condo downtown with no balcony this was really a big problem. I finally drug the mattress out onto the shared public terrace of the condo building to sit in the sun for two days. After we brought it back in it still smelled so bad I wrapped it in two mattress pads to try to cover the smell up. I still couldn't sleep on it without waking up in the middle of the night with my eyes and throat burning. I ended up sleeping in the other bedroom for about a month until the chemical smell dissipated enough for me to stand it. Amazingly enough though, my husband couldn't smell it at all and thought I was crazy. I really believe people have different abilities to smell like they do to with vision and it depends how sensitive your nose is. Nevertheless, I wish Serta would do something about the smell before shipping the mattresses out to the warehouse. It seems like an easy enough problem to fix and the repercussions to sales and possible health risks enough of an incentive.
