SureGuard Cot Bed Mattress Protector 100% Waterproof Hypoallergenic Premium Cotton Cover Smooth

I have no way of testing if it's actually doing what it claims to do. But if it's anything like the pillowcases, it's a very tight weave and lets almost no air through the material. If that's the case, then it prob does a great job of preventing dust and mite through. What I do like is the quality of construction and material. Fit is almost perfect for my Amazon Basics 10" Queen Mattress. It fits so snug that when my daughter washed the sheets, she didn't even know it was a cover, she thought it was just the mattress.

This fits perfect on my 14 inch mattress, and is very easy to put on. Recently my child wet the bed and the mattress is untouched. This is a pretty comfortable topper, we are unbothered it. It doesn’t crinkle or feel plastic. It’s very easy to wash and dried without any damage to the material. I would definitely suggest this brand and will be buying more in the future.

Works well. My daughter wanted this to protect the mattress, and help with allergies.

Good fit. True to size. Works well.

This is a quality piece of bedding, definitely waterproof, soft and no plastic feel or sounds. The only problem I have is the mattress protector stretches and leaves ripples under the sheets. My son is special needs, and has a little OCD so the creases under the sheet is an issue for him. He does move quite a lot during his sleep. I also tried sheet clips , and it still stretched. If you're a sound sleeper, I definitely would recommend this mattress protector.
