When the pillow arrived it was too full to use, so I took out 8 cups and that ended up still a little too full for me so I took out another 8 cups and while that may have been a little too much it works for me. I learned a long time ago that I didn’t really need a pillow until I switched to a waterbed. Then I started using a buckwheat hull pillow that was not adjustable. Still I found that what I needed was support under my neck. That pillow died and I got the Hullo as a replacement. Now with it as light as it is I can jam the whole thing under my neck and get the support I need. The buckwheat pillow is always cool when the night is it’s hottest and a relief to feel in those conditions.
Washing the pillow (minus the buckwheat) is something I haven’t tried yet though I’m curious to see the results. Being able to change the size to suit my needs is the feature that sold me on the Hullo and I don’t regret it.
