      Finding bedding for Cal King is a pain. This zip in complete mattress protector fits well, has an interesting texture, seems durable and fits the bill for what I needed. I would buy this brand again.

      Option: 12" White - King

      Here in ME. I don't worry about bed bugs, but I bought it because I am allergic to dust mites. I need help putting the cover on and taking it off to wash, but that is only because we have a King sized bed. I wipe it with a damp sponge every couple of changes so I don't have to wash it too often. Using it helps to keep my asthmas under control. Worth the extra work!

    • Quality product

      Price, quality, and fit was as expected (or better). Sizing was perfect. A king sized mattress is at best a bear to maneuver, but with help the cover went on smoothly. There is a little "noise", but we put a mattress cover on top and we don't even notice it.

      I really like how this cover fits over a pillowtop and memory foam mattress, however, it makes a lot a noise with any movment. I guess it is the material that keeps it waterproof (a plastic), but everytime you move it crackles. I move a lot in my sleep, and the crackles has woke me up multiple times over the past 2 nights. Overall I would not purchase this product again, but for the price difference I guess I will get used to it.

    • Fits My King Size 14" Pillow Top Matress

      The review for this 12" Waterproof Mattress Protector is exactly the same as my review for the 16" Waterproof Mattress Protector with one exception, the fit. Surprisingly, the 16" protector was huge on our 14" king size pillow top mattress, so back it went. After much consideration I decided to give the 12" mattress protector a try and ordered it. My husband and I held our breath while zipping this protector as it appeared it may be a tight fit, but zip it did. When I changed the sheets last night, I was surprised to find the protector had actually stretched somewhat allowing a little extra material all around. I checked the packaging which clearly states, "Stretch Knit"! This is my only explanation for the tight fit when we first put the protector on the mattress and a perfect fit one week later. This protector makes no noise whatsoever. Now for the rest of the story. This WATERPROOF Mattress Protector is exactly what I have been searching for. I finally located it on & at a reasonable price. For those of us who suffer with allergies to such things as dust mites, pet dander, mold spores & the like, this mattress protector totally ENCASES the mattress. For those of us with pets, babies or diapered people of all ages, it is WATERPROOF! These two features are exactly what I need as our family must deal with both issues.! This protector zips on three sides & is sewn closed on only one end which makes putting it the on the mattress extremely easy to do. I love this WATERPROOF & totally ENCASING mattress protector and highly recommend it! Thank You Overstock.

    • comfortably soft super sized to install easily

      Great product to purchase. The only downer is if one has a king sized bed. The cover is designed to encapsulate both the box spring AND mattress and had ample volume to do so but it's quite an ordeal unless there's another person to help with mattresses that are large, carry weight or are flexible memory foam which will curl unless someone else is helping to brace. And then to remove for washing it's back to the same aggravation, in other words it would be beneficial if the product were in 2pcs for a Queen and 3pcs for a King sized matress ...other than that it's quite cozy and quiet and works.well under the sheets.

    • Mattress Cover

      It is waterproof, so that's good. We have a 14 inch mattress, with a 3 inch mattress topper, and the cover zips all the way around all 17 inches without any problems. It was confusing to put on at first, and I had to let my boyfriend do it alone, but after seeing how he did it, I've had no problem taking it on and off by myself. The only thing is that it is pretty loud. But honestly, I've been hard pressed to find a waterproof mattress cover that doesn't make that scratchy noise. It works well in holding the mattress topper in place, so I like that. Also, I've got a potty training 22 month old, and it's definitely prevented accidents from reaching the mattress and topper. The only problems are the scratchy noise, and that every once in a while it like fills up with air and makes the sheets bubble up and stuff- kind of weird. But, like I said, it's a full zip, waterproof/bed bug protector... You can't really expect it to be completely silent. I'm trying to find something to put OVER it, so it's not so scratchy sounding, but don't want to get rid of it because it works so well. So you know, what can you do. You take the good with the bad.

        Thank you for your question nnana. The Bed Bug and Dust Mite Proof King/ Cal King-size Mattress Protector is made from a 100-percent polyester laminated to a urethane membrane. Polyester is a durable fabric and with this combination not very breathable. Have a great day.
