These are top-quality single ply sheets. The 800 thread count gives them a beautiful sheen. And they are delightfully soft to the touch. The stitching and workmanship are excellent. I ordered the coral queen-sized set, and the color is exactly as shown in the product description. The deep-pocket sheet fits my 16-inch mattress snugly, but it will not fit a mattress any thicker than that. The length of the top sheet is fine, but the width of the top sheet, when evenly placed on the mattress, only hangs or reaches slightly below the bottom of the mattress on both sides (16"). In other words, the sheets are "adequately" sized but not generously sized, or oversized. The sheets must be washed in cold water. If there is any shrinkage, using these queen-sized sheets on a 16-inch thick mattress will be problematic. The pillowcases are designed for queen-sized pillows and are not suitable for over-sized pillows.
