I purchased these as a filler for my King Shams.  They fit nicely, fill out the sham well, and still have a very soft/ squishy look and feel to them like you would see in a higher end hotel.  They were a little more than I normally would spend on just a sham insert, but they were worth the money.  I'd say if you were purchasing them to sleep on, make sure you buy a pillow case cover.  They are so silky, they would slide right out of a pillow case!
