I purchased this protector for my brand new mattress set,  and I was truly amazed at how comfortable it feels underneath my fitted sheets. Most importantly,  It really does repel anything liquid from penetrating onto the bed! I had no issues putting it through a washing machine either and just to be safe,  I hung it on the clothesline to dry afterwards.  I love how well it keeps my mattress like brand new! Well worth the investment for such a quality item!
