The mattress is comfortable but the smell is unbearable. I put it in the basement for three days when it first arrived, it filled our whole basement with a nasty smell which I thought was caused by large amounts of rain we were getting at the time. I used it for a few days, had to put out out again, this time in the garage, the smell seemed to diminish but was still there, so I put it in the basement again, it's been there for several days. Last time I checked it still smelled.  I'm very disappointed, am still hoping it will evaporate. 

Pros: Comfortable
Cons: Read above. I can't get rid of its noxious smell and am concerned for my health if I use it.
