The one you linked is the unofficial one I have, or at least a copy of it, as amazon didn't show the "you previously ordered this item" bar.

I just checked and it appears the one I ordered is no longer sold by that seller, but the one you linked is most certainly a duplicate and the same exact item.

The official one can be found Here it's where I got mine, this one is much more huggable, but that's simply due to it's size, which also makes it awkward at times.

The "regular" pillow can be found Here if you are interested in it.
