Using the CarbonCool™ LT Pillow is easy. Just place it on your bed and enjoy a comfortable night's sleep. Here are some things to keep in mind. When you first get the pillow, let it air out for a little while to get rid of any initial smell. Make sure to keep the pillow clean. You can remove the TENCEL™ mesh cover and wash it according to the care instructions on the label. Avoid using harsh chemicals or bleach. If the pillow gets dirty, spot clean the foam gently with a mild detergent and a soft cloth. Don't soak the foam directly in water. Also, store the pillow in a dry and cool place when not in use. This will help keep it in good condition for a long time. With proper care, your pillow will continue to provide you with a great sleeping experience for years, thanks to the 5-year warranty.
