Question: how much cotton do they contain?
Document: When I read the description, I did not count on &#34;polyester&#34; material...I should have know that for $25.00, cotton might be too much to expect...these are exceptable. tomc,Illinois
I really enjoy these sheets. They are soft, comfortable and they fit correct to size. I liked them so much I ordered another set for my self and one for my mother and she loved them also. Everyone who is saying they are not as advertised and Egyptian cotton seem to have misread because it states they are egyptian quality, not exact.
Being a guy, I don't know much about buying bedsheets. Thread count means nothing to me. Do I really need cotton from Egypt?! But these sheets are awesome! They're light, and the size completely covers my California king bed, not like so many sheets that fall short. I would definitely buy these sheets again and again.
I purchased these sheets when they were still being sold as &#34;Egyptian Cotton&#34;, so when I read the tag I was a bit surprised that it stated &#34;100% polyester.&#34;  I'm fine with them being polyester, although I thought I was getting a better deal; $25 for &#34;Egyptian Cotton&#34; is a much better bargain than $25 for polyester.
I just put these on my bed. I thought I was buying 100% cotton sheets since the description says a high thread count and also says something about &#34;Egyptian Quality.&#34; (I assumed that meant cotton). As I was placing them on my bed, I noticed the 100% polyester tag. I am NOT happy about this and wished it said 100% polyester in the description. I would return these, but it would be too much of a hassle.
Softest set I've ever had, makes sleeping that much more luxurious!
I like my new sheets and it matches my covers and its the best you can buy!! Love it very much
I have spent 5 times this much for sheets and these were just as soft...I love them & plan to order more!! !
The sheets are good quality & so soft to sleep on. I liked them so much I orderd another set.
Good sheets! Soft, smooth, comfortable. Not much more to say than that! I am sleeping great and enjoying them a lot.
Answer: I dont think any, they are microfibre,
