I had a very bad lower back pain every morning, as we rent the place and there was this old, sh*tty mattress left here. So, we decided to buy a new one and chose this Dormeo mattress. It is soft, but firm enough to support your back, side waist, everything and it doesn't matter which position do you sleep on it. It was my first day, but my lower pain is barely noticed. (I think the last few weeks affected it and that needs to "heal".) So, this mattress is highly recommended. Both me and my partner, whonis sensytive for a hard bed really love this one. Perfect for both of us. If you move there is no bouncing from inches from you. Great one!
