I had purchased this product many years ago from the mattress store where we bought our new bed at a much higher price.  When I examined it after washing this past week, I noticed it was beginning to show wear on the part that protects against wetness.  I searched the internet & when I found it through Wayfair, I knew I had a good deal & I received 10% off the price when I found a coupon through Facebook.  This is the best mattress cover protection you can buy.
