We received this topper for free from the manufacturer to review the product. The straps in each corner made fitting the topper on our king size bed easy. It fits very nicely. However, the topper does add a few inches on top of your existing mattress, so, depending on the sheets, it may be good to use sheet straps to hold the sheets in place. The topper is very plush and soft, making your body sink in. It is very comfortable and it feels like sleeping on a cloud :) We also have a down blanket and pillows so the topper, even though it is down alternative, kind of made the sleeping experience complete. Between the down blanket and this topper, it can get nice and toasty. We were thinking of replacing our mattress, but with the addition of this topper, we are going to hold off on that. I would definitely recommend this topper to anyone looking for a more plush and comfortable sleep, and even though we received this product for evaluation, I would not mind purchasing it myself.
