This Mattress Protector I almost decided NOT to buy is hands down amazing. So far my daughter has had a couple monster size “accidents” while sleeping with us. If it weren’t for the Mattress Protector, my brand new Casper Hybrid King Size Bed would have been ruined. My advice to all you buying a Brand New Mattress, protect your investment. Buy the Mattress Protector. You’ll be thanking yourself down the road like I am!!
