worked out for me
I actually removed the buckwheat hulls and just use the wool and cotton cover (and my satin pillowcase). I wanted a truly flat pillow and this was the only way to get it. Most people would not want a pillow as flat as I like it. I bought the Serenity several years ago when it was called the Boxi pillow. It appears to be the same, except the new Serenity Rejuvenation buckwheat might to be a bit smaller in length.
