These pillows are filled with buckwheat hulls that rustle when shifted around. Once you get the pillow in the shape that feels most comfortable, you won't need to move it and it should be silent. It will take some getting use to but it will provide much more head and neck support than a normal pillow

Glad you enjoy your pillow! I'm trying to spread the word about these pillows because they are relatively unknown. They are so unique compared to traditional pillows and more people should try them!
