Frankly, I was happy with spring mattresses and did not like the feel of memory foam after trying one out at a store. But my best friend was so happy after using it for a while that I went out on a limb and figured it was a matter of getting used to. I've had this for six months now and I like it very much. It hasn't cured my back problems because I didn't have any -- it is just a good bed. I usually like firm, and this is soft in a different way than spring matttresses that I grew to like. Don't want to raise anyone's expectations but Overstock got this to me by DHL the day after I ordered it.
