I bought one of these mattresses from Overstock a year ago and love it so much I bought another one for my guest bedroom. The foam does have a strange smell the first couple of days but I just leave it on the bed with no bed linens on it for a couple of days and then it's gone. These are the most comfortable mattresses I have ever owned. In the beginning the soft ones seem a little firm but that goes away in a couple of months. It's not too firm to not be able to sleep. If it was I couldn't sleep on it. I have to hae a soft mattress. Some people have said that over time the foam breaks down and gets to soft. I've been using mine for a year and it's just like it was when I bought. Of course I'm the only one sleeping on it and I weigh about 110 lbs. For the price you can't go wrong.
