Only rated the waterproof a 4 because I haven't had to find that out yet.

This item is very well made and perfect for the mattress.

I needed a cover that would stay in place once put over the mattress and live up to their claim of protecting my mattress.

Amazing quality, love it

It does what it says

This has been the best investment!My concern was to protect my new mattress and its worked like a dream. I also bought a mattresses pad for comfort.

Liked the easy way to put it over mattress. Seems to have a good quality. Durable

Does what it says and works for the purpose bought,arrived fast

great value for the price.

Just what I Wanted, At a great price
