    • Not sure how to rate it yet

      I have never owned a mattress pad before, but our sorry old mattress sure needed one. It feels good and we definitely sleep better with it than on the mattress without it. The only thing I am not crazy about is the way it tends to bunch up under the side of the bed, where my husband sleeps. I am constantly re-pulling and re-tucking it, but everything else about it is comfortable and good and I like having it.

    • comfortable

      A nice mattress pad. The sides could be made of a more solid material, it's made of some kind of mesh. Time will tell how long it will hold up. Other than that a nice comfortable addition to spare bed.

    • Sounded like it was lined with paper in the middle

      as I unrolled this it sounded like crinkling paper. I think it would be very loud to sleep on. Otherwise it felt soft and looked appealing. I wound up returning.

    • Does not stay in place

      When I first put this on, I thought it was great, but after a short while, the elastic does not keep it in place. So I am constantly having to make my bed from scratch to so there are not giant "pad wrinkles" under the sheet. I have plans to replace it.

    • Very comfortable.

      Purchased for my son, who has lots of allergies. Waterproof of his dog (just in case). Best part is that the mattress pad does not sleep hot!!

    • 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!

    • 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.

    • 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.

    • 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.
