So far we have been using the mattress for over a week and some of the issues we experienced on a nightly basis have gone away. Issues such as tingling in feet due to lack of circulation caused by the old mattress. It is very comfortable to sleep on and leads to a restful nights sleep. The only gripe I would have would be better edge support. I sometimes sleep close to the edge of the mattress and if I am too close to the edge it feels like I am close to rolling out. maybe having a little denser foam wedge coming up to the edge would provide that additional support without sacrificing what has been achieved across the rest of the mattress.
