These sheets (pillowcases actually, but I also bought the matching sheet set) washed very well and did not get super wrinkled in the dryer even though I had to let them sit for a while before I could take them out.  I washed as per the instructions - cold gently cycle and tumble dry on low (I am used to sheets saying to wash and dry with hot water and high heat).  They are very soft and comfy.  Hopefully they will wear well.
