Compared to other XL sheets I've tried, these sheets made by Tempur-pedic for their double XL mattresses like mine are a great fit and have a really comfy soft feel. I love the straps that keep the sheets anchored on all 4 corners. After you adjust the bed and put it flat again there is some wrinkling but that is expected with these beds. Just pull and tuck back under the mattress. I have washed these sheets several times already and they are nice and soft with no "pill"-ing. I will definitely purchase these sheets again.
