The cushion cover is fitted with a zipper. When you open it, an inner shell is revealed, also equipped with a zipper. That's good, because one can easily determine the degree of filling of the pillow itself. I have about half of the material removed because my pillow would otherwise have been too plump. Now it's perfect and can be crumpled by my will.
Individual does not get any!
I suspect that because of the chemical fibers, the heat dissipation does not work as good as with a feather filling. Who tends to perspire, so probably will not be happy with this pillow. Experience on my part for this purpose are pending.
