Perhaps the problem for us is that we have another memory foam pillow that is of a much higher quality and as a comparative, this one failed some. It comes very flat, it does expand, but it's still about half the size of the one we had. That said, it feels fine, but doesn't come with a protective cover. That's to say you have direct foam inside your cases unless you buy one of the zipped ones. It's OK and if you're inclined to sleep on a flatter type of pillow, you might prefer it. The memory foam -- of which we've discovered there are many varying qualities -- is just OK.
