Considering all I do with a mattress is sleep on it, and I'm usually not awake when I do that, how do I evaluate it. I've been casually looking for a mattress for 5 years and find it an interesting process. Finding an in depth article that really says anything is difficult, but, after all, all you do is sleep on the thing most of your life during the period of ownership. Today materials are adequate for almost any purpose. So the buying experience is the key item. Don't go to a place that has too many models and just get confused. It's more comfortable than the floor and looks great. No complaints to date. I do want to mention that the delivery was the best I ever had on a "furniture " item. Can't wait to try it.
