Buckwheat hulls have several advantages over traditional pillow filling like foam or feathers. Most significantly, buckwheat hulls do not collapse under the weight of your head. They provide excellent support for your head and neck. The buckwheat hulls conform perfectly to the unique shape of your head and neck. This allows the weight of your head to be evenly distributed, which will prevent any undue stress on the muscles in your neck. In addition, buckwheat hulls do not conduct or reflect heat like other popular pillow filling types. They’re breathable, allowing warm humid air to quickly escape, keeping you cool all night long. Using a zippered opening, the buckwheat hull filling can be added or removed to provide the thickness you prefer. Buckwheat hulls are also an economic choice – they tend to have a much longer life span than most pillow filling types.
