    • Easy to fit, waterproof cover

      This is an easy cover to fit onto any mattress. I was able to do a full mattress on my own but needed help with a king mattress. I"d recommend this to anyone.

    • Perfect fit

      The cover I received with a mattress pad did not fit well. This one fit perfect to the size of the mattress. Love it!

    • Good product

      I have yet to test out its "waterproof" abilities, but with a baby on the way I'm sure I shall see soon after the baby is born. Originally, I ordered a different mattress cover. That cover was incredibly difficult to put on and did not fit. This cover however fit beautifully and was somewhat easier to put on. The side zippers allow for expansion or for a tighter fit when zipped. So far, I'm quite pleased.

    • Exactly what I was looking for!

      It is roomy without being overly so, easy to zip on and has a nice cloth feel to it so your sheets don't slip off AND you don't get sweaty like you would lying on plastic. The first one I had purchased like this lasted over 8 years so it is a good value! Before I found this on Overstock recently, I made the mistake of purchasing a regular fitted plastic one from a retail chain that cost over half of what this one did and the sheets were constantly popping off so I was thrilled to have found this one through Overstock again.

    • Definite Buy

      This mattress cover expands to hold the new thicker mattresses and fully encases the whole mattress. It is thin enough to allow the benefits of the memory foam mattress to still be felt.

    • Ripped @ zipper, does not fit 18" Stearns & Foster

      I bought this item based on the HONOR system. In the ad read " "Fits up to a 20" Mattress". Well folks it does NOT...... I opened the packaging, began fitting it over the Queen size Stearns and Foster 18" mattress one end at a time alternating back and forth on each side to get even expansion. When I got to the bottom of the mattress there was NO MORE MATTRESS COVER left, yet I needed another 12" of mattress to cover. As I pulled on the cover and pressed down on the mattress the cover ripped away at the zipper.. Either I got a faulty manufactured item, or BEAUTY REST ULTRA II is full of B.S.
