This is the mattress I personally use for sleeping every night. To be honest, I was unsure at first as it felt a bit firmer than other "medium" mattresses I have had in the past, but in the last month of sleeping on it, there has not been a single morning that I have woken up with an achy back. The mattress has a nice heavy solid feel but has very nice memory form on top which cradles your body in the right places. No more sore shoulders or hips from laying on my side. I am VERY happy with this mattress.
