The discovery of buckwheat hulls in unexpected places, such as beds, can occur if the pillow has developed a tear or worn out over time, spilling its unique filling. If your roommate owns one of these pillows, it’s likely due for a replacement or a patch job.

These pillows became particularly popular during the era of late-night infomercials, with the Sobakawa brand being a household name in the 1990s and early 2000s. Their quirky advertisements touted health benefits, including improved posture, reduced snoring, and relief from neck pain.

So, if you spot these curious “seeds” in your home, you might not have a mystery but rather an opportunity to explore the quirky, comforting world of buckwheat pillows. And if you’re intrigued, you can still find these pillows today—just ensure to keep them intact to avoid a buckwheat bed invasion!
