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.
