This waterproof mattress pad so far as held up as I would have expected.  We had a whole tumbler of water spill and it did its job and kept the mattress dry.  It is easy to put on and stays put.  We haven't experienced any pulling off of the corners.  I've washed it a few times so far according to to the directions and it's been fine with no signs of wear and tear.  I'm impressed so far and would recommend it if looking for a waterproof mattress pad.
