I have been using this cover for a few months now. I purchased this because my dog has occassional accidents when sleeping on my bed. She has "tested" the mattress cover for me twice since. This cover has proved to be totally waterproof. There was absolutely no leakage thru the cover onto the mattress. I have washed it twice and it continues to protect the mattress. It is very easy to wash and dryed on low, in the dryer. The bottom that wraps around the mattress may seem as though it may rip, but I find it to be very durable. My mattress is a queen size, 16" high and this cover fits perfectly. There is also no "crinkle noises" when sleeping on it. For 3yrs I've used this same cover on my grandaughters mattress and it continues to protect the mattress and looks brand new. I have used this brand for probably 20+ years and have never had a problem. I did shop around and this is the best price I could find. I highly recommend this mattress cover to anyone who needs 100% waterproof protection coupled with a quality mattress cover.
