Antique Folding Bamboo Japanese or Chinese head rest (possible Takamakura?)

Rare Antique Collapsible folding Bamboo Chinese Headrest/Neck pillow. The legs can be folded in when not in use -- really cool intricate little contraption! Might be from the 19th century? In excellent condition. It might be a Takamakura to preserve Geisha hairstyles or some kind of (not super comfy) traveling pillow
