These sheets were super soft and cozy when we first used them. I did NOT wash them before putting them on my bed. Other reviewers indicated a smell, but the set I received was perfectly fine. As is the nature of this material, it did pill up some after a week of use, and when we washed them, we had a bunch of fibers in the lint catcher. The second week, they pilled up even more, again lots of fibers in the lint catcher, but then they started to smooth out again. We really like these sheets even if it did take a couple washings to get them back to new feeling. They are soft, warm and comfortable.
