King Size Premium Microfiber Bed Pad King ■Premium microfiber The material used has finer fibers than microfiber. Air is trapped between each fibre, so just adding one layer provides a level of warmth that is one level higher. Prevents cold feet and helps you sleep soundly until morning. ■Moisture-generating cotton improves heat retention Uses moisture-absorbing, heat-generating cotton ``Thermo Alpha.'' It absorbs sweat while you sleep and turns it into warmth. It also resists stuffiness, improving heat retention. Easy to put on and take off! Rubber bands on all four corners It's easy to put on, just attach the rubber bands on the four corners. Perfect for busy people like you! The rubber band holds it in place so it doesn't slip off easily, which is nice. Always clean! You can hand wash it at home, so you can always use it cleanly. It dries quickly and is easy to care for! *Please be sure to check the washing instructions before use. Please wash by hand.
