    • Convenient waterproof cover
      Verified Purchase

      I searched for a waterproof cover that was 100% waterproof as well as cool and comfortable. I found just that in this cover as well as the fact it is so easy to remove and launder. The sleeping surface is soft and the under side is waterproof. It zips off completely around the top and launders very nicely. Easy to zip back on for making the bed! You will not be disappointed in this purchase.

      Keeps you cool. Added benefit is that it doesn't allow the fitted sheet to slid off on the corners. Great product.

    • Queen foam mattress cover.
      Verified Purchase

      Haven't washed this yet so don't know how it will hold up, but fit is perfect for queen foam mattress I covered. I don't sweat at night, that's a good thing.

    • The best mattress encasement I've ever had!
      Verified Purchase

      I wish I would've found this a couple years ago. We've tried so many different mattress pads that wouldn't stay on the bed even with mattress clips. We had tried one other zipped encasement, but it was so incredibly hot to sleep on and made a ton of noise. We only used that 1 night and threw it away. This Pellon cooling mattress encasement actually does what it says - it does cool you. And its QUIET. I was able to get this on our king size bed all by myself due to it being a zipper on all sides. I recommend this to anyone who needs something to cool them, and protect their mattress. Well worth the money!!

    Questions & Answers

    • Q:

      "Does this product encase the mattress with a zipper? "

      • A:

        Yes it does.

    • Q:

      "Hi All - I already bought this and am using it on a 14" mattress. All is good now. However, above it says this has a pocket depth of 18 inches. Has anyone tried using this on a deep mattress? Reason I ask is my mattress is 14". I want to put a 3" topper on. Not sure if this can handle though. Seems pretty tight on the 14". Is it ok to stretch the encasement, or is the 18" a stretch of the truth. Seems like a good product, just want it to be 18 in as advertised here."

      • A:

        I too, have this on a 14-inch mattress. But the sides of mine are super stretchy and I'm sure it will fit. Plus, most toppers are not as thick as they claim.

      • A:

        Thanks for the response. I ended up returning due to this though. Not a bad product, just not as deep as they say so will not fit my needs.

    • Q:

      "Hi there, Customer Care Person! Hope you're doing well today, and can answer a question about this product. My question is – how can a product like this possibly wick away moisture and heat through the night, when it is completely filled with polyurethane?!? Have any of your folks, there, actually try this product, and if so could you give me your feedback!?! I am also in need of an answer to the question of how much each encasement weighs?"

      • A:

        Hello katadobermom, the product wicks away moisture from high concentration to low concentration area. This means moisture is wicked away from right under the person who is sleeping over it to the areas where there is no contact. As the moisture wicks away, its evaporates quickly. The person sleeping on it feels cooler because moisture is going away from his/her body and product stays dry by wicking it away to low concentration area. The polyurethane acts as a barrier to avoid any fluids to go through the pad to mattress as well as a barrier for moisture to go into mattress. The last thing you want to do it to let the moisture go into mattress which normally reduces life of mattress and facilitates dust mites and other allergens growth. Thank you for shopping with us!

    • Q:

      "Is it washable???"

      • A:

        Hello kathychad1, this item is machine washable. Thanks for shopping with us.

    • Q:

      "If my mattress is only 13 inches deep, will this pad still fit properly or will it be uncomfortably "baggy"?"

      • A:

        Hello ssmtn21, this mattress pad will work great with your mattress. It should not be too baggy. Thanks for shopping with us! L.B.

    • Q:

      "This product is an encasement with a zipper. Is the zipper only one end or half etc."

      • A:

        Thank you for contacting us, miamibridges11340. This product unzips completely on all four sides and can actually separate into two pieces. Please let us know if you have any further questions.
