Protects very nice mattress because the top is sponge (loop) soft and slightly plasticized below. I do not meet plastic noise problem as in other reviews. I washed for the first time at 40 and no problem. I previously had a quilted mattress and protects it always was very unpleasant pilling. With the above sponge no problem. I took a size up for a bed of 140 * 190 standard and therefore I did well as the seams are not too tense. that is the right size to take. fast delivery. I recommend the mattress cover.
