This helps dramatically. I have a foam mattress, however, my back pain is flaring up so I was sleeping with numerous pillows under my back and neck because of the stiffness of the mattress. By adding the mattress topper conforms better to my back and adds a softness to the mattress that I am now needing. This is good so that I don't have to run and buy another mattress in order to get a decent night's sleep.
