Writing this after my toddler spilled a ton of water on my bed (a new mattress). I didn't realize what she had done for about 1 minute. By the time I got her off the bed, pulled the sheet off and pulled the mattress protector off, the mattress was still dry! I felt the bottom plastic part of the mattress protector and could feel the coolness of the water, but not dampness. This thing works! Note, I don't know how it would perform if I had left it for a really long time. The protector is also very soft on top, not noisy, and easy to stretch over the mattress. You can kind of see the square shapes of the protector through the sheet, but I personally don't care. It was a great buy.

Good fit

Size: Queen

Covered the mattress well. It was not noisy. Sheets are wee bit oversized and the the cover helps keep the sheets from sliding around. Kids are older so it’s more for the pets. I do recommend it.
