Excellent waterproof mattress cover find
Color: 5 Beige, Size: Queen
Good quality. Backing is waterproof with quiet material being such. Top cover is soft cotton which is hard to find. Followed proper washing & drying per tag instructions results were good. Em confident it will have longevity in quality. Also, a perfect regular queen mattress fit.

Fantastic mattress cover!
Color: 4 Black, Size: Twin XL, Color: 4 Black, Size: Twin XL
My son's bed needed a new mattress cover. The old one was a synthetic material that held stains, had snags and runs and didn't last long.
So, I went hunting and found this one. I liked that it was quilted as well as waterproof, nice looking. I purchased one for my son's bed, black. Wow, these are really nice. They fit great and are so much more attractive, completely elevates the bed.
They make a bit of noise when being put on the bed but are completely silent when laying on the bed. No more crinkle sound!
I was so impressed I purchased one for my bed too! Never going back to the old covers. These will not disappoint.

Fit our California king perfectly. Goes on just like a fitted sheet. Lightly padded and is infact water proof. Exactly what we were looking for and in our budget!

Good protector
Color: 2 White, Size: King
Excellent quality mattress protector for the price. It’s waterproof, quiet, and comfortable to sleep on. I also like that it’s machine washable and keeps the mattress fresh and clean. Would definitely buy again.

Great purchase!
Color: 1 Gray, Size: California King
I am really happy with this mattress protector! It fit my mattress perfectly and was easy to put on without constantly slipping around. The material feels soft and comfortable, not stiff or plasticky like some waterproof protectors. I also like that it doesn’t make any crinkling noises when moving around in bed. It gives me peace of mind knowing my mattress is protected while still feeling breathable and comfortable to sleep on. Overall, great quality for the price and I would definitely buy it again.
