Tri-Core Cervical Support PIllow helps provide proper alignment of the spine. Two different width neck rolls on top and bottom provide a custom fit for different sized sleepers. The trapezoid-shaped center delivers great orthopedic benefits for back sleeping by cradling the head and allowing the built-in neck roll to firmly support the neck. The comfortable, but firm, side lobes support the head in a natural position when side sleeping.- Cervical Pillow, Firm Support, Standard, 24"x16" (61cm x 41cm), White (15 ea/plt) (080150)
