COOL AND COMFORTABLE - Pillow Cube keeps its cool with a temperature regulating memory foam and our Ice Cube Cover engineered with frozen fibers, so you don’t have to be flipping the pillow all night long. All 6 sides of the Pillow Cube are the cool side.SUPPORT YOUR NECK AND SHOULDERS - There’s a gap between your neck and shoulder which most conventional pillows won’t fill. Pillow Cube gives you support for your “pillow hole” which can alleviate neck pain or shoulder pain caused by unsupportive or thin pillows. Stop folding or bunching up pillows and try the pillow designed with you in mind.BETTER SLEEP ON YOUR SIDE - Side sleep is healthier for you and is proven to help with circulation, respiration, and digestion. Pillow Cube is the pillow created specifically to support side sleepers in their search for a better night’s sleep.SIZE MATTERS - Most side sleepers love a 5” pillow, but if you have broader shoulders or require more support, we made the 6” pillow with you in mind. The Pillow Cube Classic is more compact than the Pillow Cube Pro and perfect for travel, naps, or people who don’t roll around while they sleep.
