Ventilated for increased air circulation and breathability, the Zoned Dough pillow cradles the head with larger holes on the inside while supporting the neck with smaller holes on the outside. Its Dough formula creates a softer, more supportive memory foam for optimal conform. Accompanying the pillow is a luxuriously soft rayon from bamboo velour cover, excellent for sensitive skin and temperature regulation. This pillow comes in three loft heights - 4.5 low loft, 6 mid loft and 7 high loft - and two density levels - firm and plush.
