Hullo Buckwheat Organic Adjustable Cooling Pillow for Side & Back Sleepers (20×36 King Size)

Firm and grounded, this pillow is filled with buckwheat hulls that contour in a beanbag-like way, offering sturdy, consistent support. It’s also fully natural and sustainable, which is a meaningful bonus. That said, the texture, weight, and sound of the hulls as they shift make it more of a personal preference, especially if you’re sensitive to sound while you sleep.
