I am really pleased with this mattress topper. I bought it to go on a new sofa bed that is firm and has a couple of areas where the frame makes lying on it very uncomfortable. When I saw the small package I thought I had made a mistake, but I couldn't have been more wrong. It looked too thin to make a difference, but it is so comfortable I would be happy to use it night after night. It is the ideal size to cover the bed space  and a sheet covers it, neatly fits over the elastic, which secures the topper under the frame. It was a great price and delivered within a few days. I am so impressed I am going to purchase another for the Kingsize bed about to be delivered,  without even waiting to test the mattress. Great purchase.
