I'd been looking for something like this for a while, and this definitely checked all the boxes except one - the installation. The description says you don't have to remove the mattress to put it on the box springs, which technically could be true - but in order to get it to "wrap" correctly you will need to lift the box springs to tuck it under the bottom if you have any other style bed frame other than a platform...and if you need to use the elastic straps to make it taut around the perimeter of the box springs, you will need to remove the mattress completely regardless of the type of frame you have. Unfortunately, we have a very heavy king mattress, so we did the best we could. We do have a bed frame that hides the bottom of the box springs (only about 4" is above the rail), so the part I want covered looks great and we were able to get it tucked under the box springs on the end and some of the sides.
