    • Water resistance
Material Type: Cotton Size: Queen
It was water resistant and easily went over mattresses

    • Soft top, and not hot to sleep on
Material Type: Cotton Size: King
Not sure about the water resistance, as there has not been any accidents, but the top is very soft. I have noticed in the past that the cover makes sleeping hot, but I have not noticed that with this one.

    • GREAT PROTECTION, BUT A LITTLE LARGE FOR OUR CALIFORNIA KING MATTRESS
Material Type: Cotton Size: California King
We still like this product, though it's a bit larger than we thought it would be for our California King mattress. Perhaps it was made so that you could fit the box springs in it, too. I don't know. We just ticked the excess under the mattress and it works fine.

    • Better than anything else!
Material Type: Cotton Size: King
I have had this mattress protector for about a year. It's quiet, comfortable and fits my king bed perfectly. I wouldn't say there's a temperature change in the bed and it's not cushiony....because it's a pad not a topper, but it absolutely does what it's supposed to do! Just yesterday my puppy had an accident, in the middle of the bed, while I was changing the sheets. I was in the other room so i don't know exactly when it happened, but I found the pee sitting in beads on top of the protector and it totally stayed there until I could get a towel. Nothing reached the mattress! I am ordering a second one so I can rotate them when I wash the sheets. I was going to run to Target to buy one off the shelf but I'm afraid it won't be as good as this one! So I'll wait the 2 days to ship it and know I'm getting what I want! ... show more

    • Super soft and full coverage
Material Type: Cotton Size: California King
This mattress protector is so soft and comfortable to sleep on. It is also ver quiet, meaning not scratchy like our old one. There is no pilling left behind on the mattress.
