As others have stated, I was also concerned about purchasing a mattress unseen. My preference is for a softer mattress but my wife prefers firm. This is firm but still soft enough to conform to our bodies contour. I have shoulder issues and sleep on my side but both of us were  comfortable on this mattress the entire night. We are currently very happy with the price and quality of this product and highly recommend it but only time will tell how it holds up over a longer period.
