This pad fit perfectly on our crib mattress and held up great for 2 months. After several days of washing it each day, i purchased a 2nd one. Shortly thereafter the plastic on the 1st one fell apart. And after having the 2nd for only a few weeks, that one fell apart, too! i machine washed and tumbled dry on low, just as the directions say. Today i bought the "especially for baby" pad, but it doesn't fit tightly on the mattress.
