Latex Mattresses Toppers, Latex is a natural product and the only foam derived from the sap of the rubber tree. Because it is a natural, porous and biodegradable product, a latex mattress topper will conform to your body’s contours and alleviate pressure points. It will remain cool in the summer and warm in the winter, allowing your skin to breathe as you sleep. Latex mattress toppers do not transfer motion, and are an inexpensive way to improve your sleep surface without the added expense of replacing an existing mattress. 100% natural latex mattress toppers are eco-friendly, elastic and durable and highly recommended for people who would like to reduce the synthetic materials in their sleeping environment.
