Unlike a humanoid body pillow, a "skeleton-filled body pillow" lets you hear a heartbeat too, promising a deep, restful sleep

ChuukuraiLab unveiled a life-size dakimakura at Wonder Festival 2026 Summer with an internal skeleton and built-in speaker.

The product can play heartbeat sounds, support posture adjustment, and be customized for individual needs.

Orders began in July on BOOTH, with the full set priced at 120,000 yen.

The hybrid design blends sleep aids and life-size doll aesthetics, pointing to a growing market for personalized comfort products.
