I bought these sheets because of the thread count, relatively good reviews and the sheets being deep pocketed. However, after washing and drying the sheets once, the fitted sheet does not fully accomodate the 18 inch mattress depth, which means that they shrunk. We are having to pull and tug at the fitted sheet to keep it on the bed, and are fighting to be fully covered at night by the flat sheet. I am further disappointed by how hot they get in the night, it's as if they retain all of your core heat. It is late fall now and although it is cold in our house, both of us are throwing off the sheets at night. I wish I could return these to be honest, but they are used and I no longer have the packaging.
