I bought these not knowing how I would like them. I thought with buying the 300thread count they wouldn't hold up to my current 500thread count but the description for the 300thread count cotton was it feels like a 500 thread count and it's no joke they feel the same if not better. I love them. I only wish I would have noticed when I bought the king set that it came with pillow cases too, because I bought another set of pillow cases and didn't really need them since the king sheet set came with two already. The fitted sheet also has the straps that go under the mattress so it does come off and it tells you which way is bottom and top which makes making my bed so much easier. I'm known for putting the fitted sheet on wrong at least that's what my husband says. But now I never have that problem.
