I realize there are few bad reviews of this product. You have to understand that mattresses are not one fit for all. Do your research well, if you weigh more than 220 lbs, this mattress may be not thick enough for you. But if you are 170 lbs like me, this is an unbeatable deal. There are enough websites on the net to do a good research about memory foams, temp. mattresses. This is not a temperapedic mattress, however it is one of the best sleeping technology, a new tech bed if you will..It came in time as promised by OS. I didn't have any odor issues like others. I opened it and it shaped itself to original in a matter of hours.It is absolutely wonderful and comfortable to sleep on. I will get another one for my kids as soon as I can. I feel so empowered to go into a local mattress store and ask for the same price from the owner, because OS has it at that price, then walk out when they cannot beat the price because they have to pay overhead, rent, employees, insurance etc...I did enough research and one sure thing is that this price cannot be beaten. I am not sure if your "back pain" problems will disappear, nevertheless none of these products have that claim in their ads. But sleeping in a comfortable bed like this , I sure don't have my neck pain problems.Thank you again Overstock.
