I bought a bed online and it was much firmer than described. I looked for weeks for just the right memory foam topper. Not only is this one super comfortable, does not say at all, is more than thick enough and so soft! But, it also has a water proof marred cover. It not only covers the topper but my super thick 17" matress as well, which was hard to find one that just fit that alone. I highly recommend this topper for comfort, the waterproof matress pad, it's all in one and never shifts, even when I change the sheets!
