Customer Reviews & Questions
Review Summary
Summarized by generative AI from text of customer reviews
Customers overwhelmingly praise the mattress protector for effective waterproofing and soft, quiet comfort that eliminates the plastic feel of traditional protectors. Many highlight the cotton-top design, durable construction, and reliable performance against spills and stains. The zipper enclosure stays secure on standard mattresses, though some report difficulty fitting thicker models. A few note zipper quality concerns or slight heat retention. Overall, most customers express strong loyalty, with many repurchasing for additional beds.

Protecting my mattress 🙂
I love this waterproof mattress protector. It helps to protect my mattress from my kid when they accidentally spill out the water or milk. It is easy to installation.

Great mattress protection
This is just perfect to protect the mattress box spring, but it also makes a good mattress protector, no liquid goes through, perfect for a children’s mattress.
It’s material is good quality and it’s elasticity helps fit it in perfectly.

This really was not what I was expecting at all. This is not your typical mattress cover that just goes on like a fitted sheet would. The entire mattress is zipped up inside this thing and the material is like similar to a raincoat, I guess I would say?? Not really what I was looking for but either way, I have a taller queen size mattress and this did not fit it at all. This would also be very difficult to put on logistically.

This mattress protector has worked wonders! We have had no complaints from our daughter and absolutely no crinkle sounding which is so nice! The zipper seems durable and is very much hidden as if it’s a seam! It fits great to her bed and allows her sheet to fit right over! Must have if you are in the stages of potty training or nighttime training!

My son isn’t fully potty trained so this has been super helpful to keep our mattress dry. It fit our bed perfectly and when its time to wash, it has been super easy. It doesnt feel like we see sleeping on anything other than the sheet. It doesn’t protect from the a strong smell of pee if my son peed through his pull up but it wasnt like insnaely strong. Still recommend! So glad we have it!

Great!
I have been needing a mattress protector as my son sleeps in the bed sometimes. This one is very durable and feels good on the bed. I’ve had others in the past that do not feel like they will last and were uncomfortable - this one is not like that!

Hi char. The Company Cotton™ Waterproof Mattress/Box Spring Protector - 16". Constructed of tightly woven, breathable 300 thread count 100% cotton percale. The 16" drop should work well with your 13.5" deep mattress. This will allow for ease in putting on your mattress. When laundered according to instructions, any shrinkage should be minimal to none. With the 16" drop on the mattress protector, you will have a buffer should any shrinkage occur. Thank you for your inquiry.

What is the pore size in microns, please? Does the zipper have a cover at the end of it? Thank you.

Hi Noel. The Waterproof Mattress/Box Spring Protector. The average pore (open space between interlocking yarns) size is <15 microns. The average bed bug is visable to the naked eye at 1/4"" to 3/16"". A quarter inch= 6350 microns. In contrast, dust mites are microscopic at an average of 250 microns. The cover has a zipper at the end that wraps around the corner. Thank you for your inquiry.

On your mattress/box spring encasement, they are separate encasements is that correct? One encasement for the mattress and one encasement for the box springs?

Hi Cindy. The Company Cotton Waterproof Mattress/Box Spring Protector is designed to cover a mattress or a box spring. This product is offered in a 9"", 12"" and 16"" size to accommodate the depth of your mattress and/or box spring. Typically a mattress and box spring used on together on the same bed are the same depth as each other, however if they are not, you should choose your size accordingly. Thank you for your inquiry.
