Our proven, pressure-relieving memory foam has now teamed up with the natural antimicrobial and climate-controlling power of copper. The Copper Memory Foam Mattress Topper kills bacteria as you sleep, acting like a self-cleaning, odor-neutralizing layer atop your regular mattress. In addition, this cutting-edge foam formula is packed with a double-whammy of temperature regulating benefits, like cooling gel in addition to its already highly conductive copper microparticles. Together, these ingredients do the heavy-lifting of trapping body heat to keep you comfortably cool throughout the night. And to ensure that every inch of it is completely perfect, it's covered by our 5 year worry-free warranty. It's the mattress topper that delivers on pressure points, comfort points and one heck of a price point. We'll sleep to that.
