I bought these sheets because the majority of the reviews were positive. However, since I received them, I have been very dissapointed. At first they were very smooth and soft. After the first wash, they were fine, but after using them for a week they became rough and bumpy. Also, they are hard to fit on my 12 in thick mattress. according to the description, they should fit fine. They ceraintly do not reflect a Eguypian Cotton 530 thread count sheet set. I have ordered other sheets hoping to replace these and I have had them less than a month.
