I have been sleeping on this mattress about a month. I like it a lot more today than I did in the beginning. Make sure you have supports in either a box spring or slat supports. At the same time, know that this mattress is tall tall tall. I have a 5" box spring type setup, and with my bed frame, I would not want to go any taller.  I am a side sleeper and this plush mattress was a little hard to get used to at first, but I am liking it better now. I have trouble with shoulder pain and that pain is better now.
