Our sleep has definitely improved with this mattress! We did not realize just how badly our last mattress needed replacing until our first night on this. We have different preferences on mattresses too- he is more firm whereas I like more plush. This mattress pleases us both! The mattress itself is firm, however the pillowtop adds the comfort I expect with a plush mattress. We shopped around for a long time before buying, always declining to follow through with a purchase due to either liking the quality, but not the price or vice versa. This mattress just fits the bills all around! We both also have back issues, and been improving and feeling better every morning after sleeping on this. What a comfortable, restful, and reviving night's sleep. Highly recommend!
