If I put only 4 stars is that the side with the insertion neck is more pronounced is also thinner and crashes faster and does not take shape very quickly, but as I specify the highest returns the pillow and I am again well supported.
The size and weight seemed exaggerated to me, but they allow less move.
I put it in my pillowcase because the cover provided is really crappy, the zipper is difficult to catch the plastic and not necessarily pleasant.
I forgot, it can also seem a little hard at first, but it's a matter of habit we must tame it after I think it will be difficult to move on.
