This mattress pad made my firm mattress utterly luxurious, however, the backing is very "frail." One run through my high efficiency washer started shredding it. If you have a washer without anything to grab onto material, you may be able to wash this, otherwise I just "wash" it in the sun and shake it out. Note that this is very thick padding. My deep sheets barely fit over it. I had no idea just how plush and thick this would be when I ordered it. Regular sheets are not going to fit over this well. But...it's very comfortable.
This mattress topper is very soft and has enough foam that you can sink down into it. The only downside is that it doesn't have adequate tension to stay n the bed and it tends to take the bottom sheet off or nearly off constantly.I am sooooooo happy with the comfort, but with these other things gonig on, don' get much sleep
