These sheets are great, I washed before putting on bed which came out pretty well after washing and drying. The sheets did have little wrinkle which was totally fine because it did smooth out when it was placed on the bed. The quality was fine and most of all all it fit my 10" mattress along with a 4" mattress topper, So I would say the sheets are approx. 15" deep after washing and drying on high temp. I love my new sheets I got them in "Taupe" Great color its sort of neutral Will definitely buy again and must say it was supper fast shipping. Seeing is believing! Thks overstock!!
