Infused with bamboo charcoal to regulate humidity, temperature and odors, the Zoned Dough® Bamboo Charcoal pillow is paired with Zoned Dough® technology for one of the best sleep materials available. Its Zoned Technology™ cradles the head with larger holes on the inside while supporting the neck with smaller holes on the outside. Additionally, the Dough® formula creates a softer, more supportive memory foam that is naturally antimicrobial and hypoallergenic creating clean, long-lasting comfort. Accompanying the pillow is a luxuriously soft rayon from bamboo velour cover, excellent for sensitive skin and temperature regulation.
