I feel this item is a great value considering that similar items sell for 3 times as much or more. Its very comfortable, much more so then a conventional spring matteress. I think Nasa engineered the way this item is packaged. It arrived in a box 1/10 the size of the matteress, compressed, rolled up and and wrapped in plastic, once it was unpacked, and the multiple layers of shrink wrap are removed, it unrolls expands to normal size. DHL shipping was fine also. Overall I'm very happy with the purchase.
