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.
