We've now purchased 3 sets, two sets of sheets (Royal 1000 Thread Count, Chateau 800 Thread Count) and these pillow cases. We didn't purchase the sheet set because my wife didn't want white (Split King only available in white). The Pizuna fabric is the thickest. After one washing they are rough and not very supple. There is no doubt of the quality of this fabric. Does 1000 thread count make a difference? Definitely!! It will likely take a good dozen washings before they would be very supple and comfortable. They are VERY much worth the money. Of the 3, these represent the best value. I can't comment on the fit of the fitted sheets given we purchased the pillow cases but the pillow cases are very large. Really, too big! (King) Once they're washed enough and become more supple their large size will not be bothersome. After one wash they are bothersome.For now I have this pillow case on a formed latex pillow that I put between my legs at night. They are too rough, right now, to be against my face. I'll say this, once they've been broken in I suspect they will be the best of all three. So, in assessing the 3, I would pick these above any that we have tried or compared to. The Pizuna 1000 thread Count sheets represent an exceptional value!
