I will never go back to another bed or brand of bed! This bed is amazingly comfortable and perfect balance between firm and soft. Medium firmness is the way to go. My back loves it and it makes me not want to get out of bed in the mornings. The pillow top is so comfortable and soft. Very durable and heavy bed which will last me quite a long time. I will only own Serta beds now because I am happy with how much care and thought they put into their beds. I sleep so well at night!
