"IMPORTANT: Activate the CarbonBlue cooling by placing this pillow in front of a fan for 12-24 hours after opening. This will cool the pillow after high temperature exposure during shipping. It will also accelerate dissipation of new memory foam odor. HYPER SLIM - ONLY 2.25 INCHES HIGH: The standard sized Max Cool version of our Hyper Slim pillow offers a low profile that keeps stomach and back sleepers comfortably aligned without the bulk of traditional pillows. MAX COOLING: Enjoy instant cooling relief from our CarbonBlue phase change material. While no pillow can stay cold all night, CarbonBlue is engineered for that first, refreshing burst of comfort to help you drift off with ease. PREMIUM, SOFT MEMORY FOAM: Our CertiPUR-US certified gel memory foam offers medium-soft support without excessive height. It cradles your head and neck, helps open your airways, and may ease snoring and pressure on your shoulders and back. COOL-TO-THE-TOUCH, WASHABLE COVER: A zippered, cool-to-the-touch, removable cover makes it simple to clean. This cover was specially designed to work with the CarbonBlue cooling material. Just toss it in the washer and dryer to keep the pillow hygienic and feeling like new. WHY CHOOSE BLUEWAVE? We're a family-owned business committed to innovation and exceptional customer support.
