I carefully read all the reviews of the various waterproof mattress covers, wanting the very best for my expensive new mattress, while at the same time not paying the very highest price. The Candice Olson pad came in with excellent reviews and a medium high price. The top feature (after being waterproof) was the QUIET waterproof material. Thus, we now have a smooth, soft, and perfectly quiet waterproof mattress pad, one that will protect our investment. I have not specifically tested the waterproof properties but based on the reviews, I believe this will satisfy my requirements. If something changes, I will come back with another review.
