My go to for all beds

Fits perfect. I like that it's like a fitting sheet instead of the zippered ones because it makes it easier to pull off and put back on during washes.

I Like It!

For the price, this is great. Some reviews say it makes a loud "sound". That isn't the case with mine. It makes no noise, even when moving around a lot on it. I have it on a twin bed that also doubles as a couch in my tiny house, so it gets sat and laid on all throughout the day and night , and there is no noise. I have it pinned so it stays in place, but l haven't used it "unpinned" so l don't know if it stays in place without pins. I'm very pleased with it, nonetheless.

Cooling!? Yes, please!

Haven't tested the waterproof claim, but definitely cooling. I've always said your mattress should not be without a cover and this is a great, inexpensive option.
