These sheets are advertised as 530 thread count, but I have to question that. They are softer than the 200 count sheets that I usually buy, but they feel very lightweight and insubstantial. I expected sheets with a very high thread count to be heavier, like hotel sheets. Also, the top hem of the flat sheet tore apart after just two days of use. I have never had this happen to any sheet, even the $10 ones I get at discount stores. They are VERY cheaply made and I cannot recommend them.
