I purchased two of these for twin mattresses on a daybed with pop-up trundle. I have not laundered them as of yet so I will have to update this review at that time. I did have a guest accidentally spill a little water on one during the night and it did not reach the mattress so I am pleased with that aspect. There is no "crinkly" sound which I have experienced with other waterproof covers. The quilted top was the main reason I chose these as I wanted a little extra padding on top of the mattress. I am very satisfied with the purchase and would recommend the item to others.
