Very peculiar material. Chucked straight into the washing machine, as one would with new bedding and came out so creased I was absolutely disgusted. After the dryer it was even worse. However, when on bed, still looked creased but quite cool and comfy. Fitting is deep, which is what I was after for my deep mattress. (Photo is after I have slept on it for a week. That's a lie, two. lol)
