    • Not a good fit

      Our memory foam mattress isn't even 14" deep, yet this mattress pad doesn't even go to the bottom of it, so it doesn't stay tight around the mattress causing the pad and the sheets to bunch up. If it had fit, it probably would've been great. But back it goes...

    • Quality looks great

      I would have given this five stars, but not really whisper quiet. I am using these in the guest room for grandchildren, so felt a waterproof pad was a wise idea. They no longer wet the bed, but spills happen.

    • Sealy Egyptian Waterproof bed pad

      Sealy Posturepedic 300 Thread Count Egyptian Cotton Waterproof Pad. I have purchased this pad in the past and very satisfied with product. I especially like the material on the side panels, they seem to hold to the bed without stretching material out.

    • quality mattress cover/pad

      Needed to replace existing mattress pad. This is good quality for the price. Easy to fit, waterproof but not stiff or noisy. Wouldn't know was waterproof fibers by texture, pleased it looks and performs well. Comfortable, just what we needed.

    • Oh so Soft, and VERY COMFORTABLE!!!

      This Pad is very comfortable, and adds a more cushion-y feel to My Memory Foam Mattress. The original pad was waterproof as well, but over time, its usefulness has waned. This Egyptian Cotton Pad makes for an extra-comfortable sleep!!! You won't regret EVER purchasing one of these!

    • How deep a mattress will the twin XL fit? Ours is 17 inches?

      • Hello Kitty922, the recommended mattress thickness for this item is approximately 18 inches. Thank you for shopping with us!

    • When might this item arrive? My son's bedding is coming in 2 weeks. Thanks

      • Hello hfezza, most orders ship within 1-2 business days unless stated otherwise. It will then go through USPS, UPS, or FedEx. I hope this information helps, have a good day!

    • Is this good for sofa bed that isn't very comfortable?

      • Hello Luithe3rd, this is more of a mattress protector. I would recommend a mattress topper with a 3-4 inch memory foam to make your sofa bed more comfortable. Thanks for shopping with us.

    • Is the waterproof Dry-Lock barrier a plasticy type material? I'm asking because I've had mattress pads with that before and when you wash them the water pools in the pad so that when you remove from the washer you have water that didn't get rinsed out.

      • Hello Jamie, these are machine washable, i would recommend providing time to let it dry before using it again. Thanks for shopping with us!

    • Will this protect from Bed Bugs? Larry901

    • Will this product fit a 10" memory foam mattress?

      • Hello rachelfreitas79, yes, this will fit mattresses 13 to 18 inches in thickness. With your 10 inch mattress you can simply tuck any additional fabric under the mattress, and your top sheet will help keep everything snug. Thank you for shopping with us.

    • What is the Dry-Lock barrier? Is it polyurethane or other material? I'm looking for a tight weave cotton or polyester that creates water-resistant effect.

      • Thank you for your question, jislove. The backing of the Sealy Posturepedic 300 Thread Count Egyptian Cotton Waterproof Pad is a whisper quiet, laminated, polyester, fabric that offers the waterproofing of this pad. Have a great day.

      • Hello Gram, I hope your day is going well. The pad comes from China. Thank you for shopping with us.

    • how thick is this mattress pad?

      • Hello vche, this mattress pad is approximately 1 inch thick. I hope this helps. Please let us know if you have any additional questions. Thank you for shopping with us!

    • Is this mattress pad good for a child who may still occasionally wet the bed?

      • Hello laactriz74, yes, this is a durable, waterproof mattress pad. Thank you for shopping with us! Terri D.

      • Absolutely or for the elderly who might have an accident. I would recommend it 100% as there is no plastic feeling to it. Great quality.

    • does putting a mattress pad over a mattress topper change the properties of the topper, like heat control, comfort etc

      • We bought a tight top bed and added a mattress topper so we could change it out in a few years when it breaks down. Adding a waterproof (not plastic though) mattress protector over that did not increase the heat. The whole set up is slightly warmer than sleeping on the mattress alone but not enough to bother me.

    • Does this pad keep cool while you sleep? Or does it lock the heat in? Thanks!

      • Cool

      • absolutely!

      • we have found that it stays cool. it is not like the old plastic ones. it feels nice.
