I gave these fitted sheets 3 stars only because I really have to question the stated 400 thread count, and I think other people who buy them should too, they are a lot thinner in texture than my old sheets.
Work this one out, I also ordered the 200 thread count pillow cases, same make, they are thicker in texture than the 400 thread count sheets  hmmm ?
Quite disappointing Wayfair, I think the stated 400 thread count should be looked into.
