I've been looking for a nice, thick, high thread count sheet for almost a year. It seems that the thread count is a random number, and it doesn't mean that they will be thick. Based on other reviews, I took a chance with these and I was not disappointed. These are nice and thick, but still soft. I expect they will soften more with washing. They fit our pillowtop mattress and the top sheet is long enough to stay tucked in. I have already ordered a second pair!
