Using this sofa bed mattress pad is easy. Just place it on your sofa bed, and the snug skirt will keep it in place. When you sleep on it, the 3M treatment will keep you dry and cool. If it gets dirty, simply follow the care instructions. Machine wash it in cold water on a gentle cycle and separate it from other clothes. Avoid using bleach. Tumble dry it on low and take it out right away. Don't iron it. If your home washer or dryer is too small, use a commercial one. Keep this mattress pad clean and it will provide you with long - lasting comfort.
