first off - this is a QUEEN - when i got it it wasn't noted and everyone gave different sizes. you can get a standard pillow case on it, as long as you don't want slack. it does come with a pillow case is very nice- however it has polyester in it, and i don't know why i was under the impression that it was totally cotton. it was one of the reasons i got this pillow. i'm allergic to poly.
