Item is exactly as described. We are using it with a memory foam mattress (11in?) My sister suggested it after she bought it, and we are very pleased with the purchase. Doesn't have the plastic, "crinkly" feel like I think of with something water-resistant. And we got it just in time - one of our dogs actually urinated a little on the bed (due to a UTI) a day or two after we purchased it and it worked! No urine seeped through and it cleaned up beautifully. I don't know what the going rate is for these sorts of things, but so far it has proven to be worth the money.
