I shopped for a while to find a decent mattress protector and finally purchased this one.  It fit great around my mattress after I washed it and you can't even tell that it's there when you are sleeping.  The material is nice and doesn't make any crinkling noise when you move. The only downside is that when I zipped it closed the zipper slid right off and won't go back on.  Even though it has been a good protector, I'm not exactly happy that I'll have to purchase a new protector when it's time to wash it since the zipper can no longer zip.
