This protector seems like a good quality product. I was able to place it on my mattress by myself with considerable effort but having a helper would have made it a lot easier. The bottom of the mattress pad is the waterproof plastic layer and the top of it is soft fabric. This protector would fit the fattest pillowtop mattress around in my opinion. I had plenty of extra space once I got it on. It is a bit crinkly which I cut down on by topping with another tighter mattress pad that keeps everything in place.
