    I bought this mattress protector for our bed and the quality is much better than I expected! It's not noisy or uncomfortable like the ones that feel like you're sleeping on covered plastic and it's quite comfortable and cool on those hot nights! I also love the idea of being able to zip the top of this pad off when I need to launder it and the bottom half remaining on the mattress so I don't have to fight to get the cover off or put it back on again. All in all, I am extremely happy with my purchase and fast shipping time! I would purchase his product for my other beds.

  • Comfortable and breathable.

    I got this for my son to use at college. A twin XL. It is a great product. It's easy to put on. It would even sit with a much thicker mattress. It feels lightweight, very sturdy and protective. It does not feel plasticy at all... Also very comfortable. My niece got a different bed bug mattress protector her dorm room at a local * and she did not like it as well as this one. I think this will last him all through college and beyond.

  • waterproof and convenient

    Have been using this protector for a few months now. It is truly waterproof but does not feel plasticky as most other waterproof mattress protectors I've tried do. It is also easy to launder as you can leave the bottom half in place and unzip to remove the top half (you don't have to lift up your mattress every time you want to wash the protector).

  • Keeps you cool on hot summer nights!

    I received this mattress protector as a product test from the manufacturer for our Queen bed. We had a mattress protector from Wal-Mart and you can definitely tell the difference. My wife and I have been having trouble sleeping because some of the hot nights this summer and I have woken up sweating even with a fan. The fan can't reach in between the mattress and my body so that's usually the biggest problem. Since we switched out the old cheapo protector for the Sleep Tite mattress protector, the advertised "Wicking Tencel" has kept us much cooler even through a cotton sheet and I've been getting much better sleep at night. Another difference between our old Wal-Mart mattress protector and the Sleep Tite is that it covers the whole mattress and is water-proof which means the mattress will last longer and is fully protected. It also isn't loud and crinkly like the some of the other water-proof mattress protectors I've tried. I would have bought this protector for the temperature regulation alone but all the other protections it offers plus it doesn't feel plasticy makes it a great deal.

  • So far so good!

    So far so good! I grew up using a mattress protector. However, the quality of it was sub-par when compared to this mattress protector. This is the real deal! First this mattress protector encompasses the whole mattress. Second this mattress protector is breathable! I remember the ones on my old beds getting extremely hot and uncomfortable. With this mattress protector you won't even recognize that it is there. Last of all this mattress protector does not make the obnoxious noises that the old mattress protectors used to make. Let's be honest, mattresses cost a lot of money. This is the right way to protect your investment!

  • Worth the Investment!

    The six-sided protection is kindof a cool idea... The bottom (what lays underneath the mattress) is elasticized, so it fits the mattress snugly. The top attaches to the bottom with a 360 degree zipper, so it can easily be removed for washing. I have to say (and it's also in the instructions), you definitely need two people to put this on the mattress the first time! One person to lift and support the mattress; one person to slide it on and zip it up. After that, it's no more difficult than tucking a blanket into your bed frame. One funny thing to note: if there's an air bubble after zipping it up, you may need to unzip a little and press the air out! :) It is waterproof - we tested it by pouring water on top and waiting to see if it would soak in. The majority of the water beaded up on top. Some of it absorbed into the top layer of the mattress protector, but because of the waterproof layer underneath, the mattress remained dry! It's also quiet. You'd think that a plastic layer under the sheets would crinkle and be uncomfortable, but we don't even notice that it's there! It doesn't make any noise at all, and it's made of soft, pliable fabric that molds easily to the shape of the bed.

Questions & Answers

  • Q:

    "Does it work with 16.5 inch pillow-top mattress?"

    • A:

      Yes, it should fit that size just fine. It's very well made. Just make sure and follow the washing instructions - you can't put this in the dryer!

    • A:

      I have it on a 15 inch mattress and it fits well. The bottom portion of the cover has seams that stretch and even with my 15 inch mattress it has more room to stretch. It might be a nice snug fit but I don't think you will have a problem getting it on 16.5 inches deep. Hope that helps!

  • Q:

    "Because I am going from my smoking home to a non smoking home, will this mattress encasement keep my smoking odors in. I ask this because I see that it has Polypropylene in the fabric. Polypropylene is a form of plastic. I just don't want my mattress to make their home smell like smoke."

    • A:

      All of our encasement are waterproof but also breathable. This prevents odors from being trapped in the encasement. Your mattress may have absorbed some of the smoke smell.

  • Q:

    "Would this encasement fit snugly over a ten inch mattress. I don't want extra fabric uncomfortably bunching under the sheets."

    • A:

      Hello Lois g., there is a chance it would be slightly loose, but it should not be too large for your 10-inch mattress. Thanks for shopping with us!

  • Q:

    "would the Slumber Solutions Choose Your Comfort 14-inch Queen-size Gel Memory Foam Mattress work with this product?"

    • A:

      Hello JoelG, this will fit a mattress up to approximately 22 inches, it should work well with the Slumber Solutions Choose Your Comfort 14 inch Queen size Gel Memory Foam Mattress. Thanks for shopping with us!

  • Q:

    "Why did you choose this product?"

    • A:

      waterproof and temperature regulating mattress protector.

    • A:
