Ok, I was skeptical about buying a mattress online, mainly because it was so much money and there are no returns. So I went ahead and bought a King size 9in memory foam-med firmness. Unlike the horror stories, There was no odor, and it re-expanded overnight after unpackaging. i have to say i was impressed. i'm a larger guy and my wife is petite, but both of us are able to get a great night's sleep. after a month of use i am still very pleased. Definitly a bargain!
