I was a real skeptic upon delivery of this mattress. It arrives in a box about half, if not more, the size of the mattress. When you take it out of the wrapping, it immediately starts to expand, to its full  
thickness. At first, it felt too soft, but once I lay down for the night, I had a great night sleep. This mattress is so comfortable and well made. This would be something I would buy to replace my other mattresses as needed. A great value at this price point.
