Our Arctic Sleep Cool-Blue Memory Foam Pillow is made with a revolutionary cooling memory foam - the infusion of blue cooling gel into the memory foam helps to regulate the temperature of this pillow while you sleep; that means if you have a tendency to get very hot while sleeping, you can experience a cooler, more inviting sleep thanks to the temperature regulating gel infusion. Our Cool-Blue Memory Foam Pillow is also ventilated to make the pillow breathable and further helps prevent heat build-up while you sleep. It's contour shape combines both head and neck support to help provide the ultimate in stress relieving support; combine this with our super soft memory foam and cooling fabric cover and your head will feel like it is resting on a cloud! Removable cover is easy care machine washable.
