Upholstery filling
Buckwheat hulls are used as filling for a variety of upholstered goods, including pillows and zafu. The hulls are durable and do not insulate or reflect heat as much as synthetic filling. They are sometimes marketed as an alternative natural filling to feathers for those with allergies. However, medical studies to measure the health effects of pillows manufactured with unprocessed and uncleaned hulls concluded that such buckwheat pillows do contain higher levels of a potential allergen that may trigger asthma in susceptible individuals than do new synthetic-filled pillows.

Production
In the northeastern United States, buckwheat was a common crop in the 18th and 19th centuries. Cultivation declined sharply in the 20th century due to the use of nitrogen fertilizer, to which maize and wheat respond strongly. Over 1,000,000 acre were harvested in the United States in 1918. By 1954, that had declined to 150,000 acre, and by 1964, the last year annual production statistics were gathered by USDA, only 50,000 acre were grown. However, it may benefit from an "explosion in popularity of so-called ancient grains" reported in the years 2009-2014. In 2017, world production was 3.8 million tonnes, led by Russia with 40% of the world total, followed by China with 38% and Ukraine with 5%.
