I love a luxurious sleep. And once or twice I may have splurged on some high thread count sheets.
Turns out... that may have been a waste of money.
According to an article from REAL SIMPLE, any thread count over 430 doesn't make it any more luxurious. Rather you should look for the terms, "long staple cotton" or "Extra Long Staple Cotton."
The longer fibers give it a softer feel.
Good to know!
