The Lucid Charcoal Memory Foam Mattress Topper brings you the benefits of memory foam combined with the benefits of charcoal. Bamboo charcoal has many great qualities: it eliminates odors, absorbs excess moisture, regulates temperature, and is an excellent choice. Combined with contouring memory foam, it is an innovative master piece. Bamboo charcoal is created from the plant. First it is burned at high temperatures, then it is ground into a fine powder. Finally, it is infused in our memory foam. This topper is ventilated for superior airflow and temperature regulation.
