These are really nice sheets at a great price. We have firm deep matresses with a 2" mattress topper for comfort. The fitted sheets fit nice and snug and hold the topper in place. I am a snob about good sheets and the feel of the sheets is clearly quality. Since we switched from a standard king to split king I need to have another set to make athe bed right away when we launder our bedding. I waited to see if I liked these and I definately do so I just ordered another set.
