I got these sheets because they stated that they were cotton with a 525 thread count. I should have read closer because they are a cotton blend with polyester. I know that they do that so the sheets don't wrinkle, but I honestly would have the feel of 100% cotton with wrinkles than this blend of materials. The sheets are okay just not my favorite and I wouldn't buy another set. However, if you like this blend they are of good quality and wash well.
