Four inches of memory foam will be more soft as there is more memory foam to absorb the body weight in a more equalizing distribution of absorption. If you like more firm, then the 2" memory foam would be the choice. I suggest that you test both. Lay on your side for awhile and see if the density allows your spine to achieve a straight line between your hips and shoulders. There are retailers who will allow one to test their mattresses for like 30 days.<br><b>References : </b><br> scottish_susy2000
