Designed to correctly align the spine and support the neck in its natural position for side and back sleeping. 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. Two different width neck rolls on top and bottom provide a custom fit for different sized sleepers. The generous side lobes are taller for side sleeping and help support the neck. High resiliency fiber springs back when compressed for exceptional comfort and durability. The blended cotton cover is breathable and soft to the touch.
