The Core Products Tri-Core Cervical Support Pillow is known for relieving the neck of any and all pain, while correctly aligning the spine in its natural position. This orthopedic pillow has two width neck rolls so it can provide the proper fit for any type of sleeper. For side sleepers, the lobes on each side are larger to provide the custom fit needed to sleep comfortably. The pillow comes with a blended cotton cover that is breathable and super soft. The Tri-Core pillow fits a standard-sized pillow case and is considered more firm than fluffy.
