Bamboo charcoal has been used in medications and skin care products, and is completely safe to use in fabric and bedding products. This topper is ventilated for superior airflow and temperature regulation. The Lucid 3 Inch Bamboo Charcoal Memory Foam Mattress Topper brings you the benefits of memory foam pressure point relief combined with the odor and moisture control of bamboo charcoal. Bamboo charcoal has many great qualities: it eliminates odors, absorbs excess moisture, regulates temperature, and is an excellent choice for people with allergies.
