This Bamboo Charcoal Gel Memory Foam Mattress Topper combines moisture-wicking bamboo charcoal fibers in both the cover and foam core to actively regulate temperature and keep you dry. The breathable knit cover features 30% bamboo charcoal, while the gel-infused memory foam enhances cooling and airflow.

Ideal for any sleeping position, it adds a plush, supportive layer to your mattress-perfect for bedrooms, guest rooms, or dorms. Color: Grey.
