We have only had the mattress a few days but so far, we have enjoyed restful sleep. The "SF Estate Soft" mattress is actually a "firm" mattress but is very comfortable; not too firm and not too soft. We paired it with an adjustable frame and enjoy the ability to choose a slightly inclined position for the head and foot area. I think we made a good choice for ourselves. Stearns and Foster has been in business many decades and if their mattresses were not superior, I don't think they would still be in business.
