Amazing !! It actually works great.. have an senior dog that doesn’t quite make it out in the morning and I just needed a good water proof covering for my mattress so the day after I put it on he didn’t make it and I was so afraid that my mattress would be soaked again and much to my excitement .. it was absolutely dry!! I love it when you make a purchase and it does what it says! Saved me from cleaning my mattress !! Would buy another one if needed !! Thanks so much
