After 6 months both of our backs began to hurt. We tried to replace the mattress or pro-rate it. But there was no structural defect so Serta would not 'switch' it out.

I would not recommend this mattress or company.

If you need back support stay away from this mattress.

I bought this mattress in Nov 2012. The first 10 months were okay. I say okay because I had to get use to the memory foam which was nice and firm as it should be for a form mattress. Then it happened, it started to break down on the one side I slept on. So I rotated the the mattress and soon after that side also broke down. So when you look at the foam mattress you do not see a sag, but when you push with your hand you can feel there is nothing there for resistance or support. I have called the retail store which sent a service man out to look at it, He even said yes that the bed had broke down and had no support. I was notified today that Serta was turned down my warranty request because it has not sagged the 1 1/2 inches requested to measure the sag test. Wow!!!!! NEVER BUY FROM SERTA.

I would trade both my wife and dog in before getting rid of this bed! I've had two back surgeries in my past and I have not had any problems with my back since we purchased it. I was very sick for while and In bed for 4 solid months, that bed still feels perfect even after weighing up to 212 pounds during that time, I'm now 175. People should be required to post their weight on this site as I don't care what you buy, If you weigh 400 pound, you are going to leave an impression. It's well worth the money!!! Make sure you buy Deep pocket sheets As to the Oder, I don't have a clue what they are talking about, however we have a mattresses cover that Room-to-Go recommended.
