I LOVE my Hullo (14 x 20). I’ve had buckwheat and millet pillows in the past, but the hulls weren’t as fresh as these are, which actually makes a big difference. If you haven’t used a buckwheat pillow before, they are somewhat firm. They are also adjustable in two ways – the first way you can adjust these pillows is by adding or subtract hulls so that your head is cradled just right. The amount I took out seems minimal, but it made a huge difference for me. I played around with it quite a bit before settling on the right amount, and I kept the extra hulls around in case I need them later.
The second way the Hullo is adjustable is that you can move the hulls around so they best cradle your head each time you move.
There is a rustling noise as you adjust the pillow and the buckwheat settles into place. It might bother some people, but I find it very relaxing.
