Just moved in to a new apartment that came furnished with a really old uncomfortable sofa bed. Bought this to put on top and now I don't even feel the springs anymore. Only down side now is I can't close the sofa bed to the sofa position. Overall a great buy, too bad I saw the one $40 cheaper two weeks later but it didn't have a 1 1/2 inch fiber bed mattress topper included. By the way be cautious, I just ripped it by accident recently by moving it.. it tears easily but very much what memory foam should be.
