First memory foam mattress I buy and it's not what I expected from a smell point of view. The smell was so bad it made my eyes tear up when I laid on it. I bought it for my 7 yr old, worst thing I could of done as he is asthmatic. I've read somewhere to wait 3 months for the mattress to aerate before sleeping on it. I'm on my last month as it seems to work as the smell is diminishing. The overall comfort of the mattress is excellent in the short periods that I laid on it.
