My wife and I have tested this out several time and it’s definitely waterproof!

Excellent quality, met description, good pricing

So far they seem to do the job. I am hoping they hold up to the multiple washings per week over the course of time.

Great - using these in a rental condo that I own. Cleaning people are really happy with the quality of these.

The material is very thin and feels kind of cheap. I have not yet tested it to see if it is waterproof.

Good mattress cover at very economical price. It does not stay on mattress very well unless you tuck corners in as far as you can reach.

I got this for an amazing price of under $10. However, it fits well but could cover underneath more. Also, it causes sweating.

I put over comforter cover for my puppy if he has an accident..Works great..washes good..dries good..not hot to sleep under..

This is a perfect waterproof mattress pad. Fit a king size bed just right. Very reasonably priced for such quality.

Fitted sheet for twin and XL-twin does the job of covering even when the adjustments have been made. Our expensive mattresses are protected.
