Woven with a blend of cotton and COOLMAX®® fiber, this sateen mattress pad works overtime to keep you cool by pulling moisture away from your skin (which, of course, results in quicker evaporation and cooling). We won’t get into the science of it, but trust us. If you like your bed crisp and cool, look no further. Repel·A·Tex® stain release keeps it looking new longer. Generously filled with hypo-allergenic SensorLOFT® polyester, providing superior support, comfort and loft.
