Will it fit a Twin XL mattress?

Yes. It is sized for Twin XL, which is 80 inches long, so it matches the length of a Twin XL mattress.

Is it really waterproof?

Tempur-Pedic lists it as waterproof, so it is designed to block spills and accidents from reaching the mattress.

Can I machine wash it?

Yes. It is machine washable. Follow the care label and tumble dry low or line dry to protect the waterproof layer.

Does it change how the mattress feels?

It is a thin polyester layer, so it adds little cushioning. Some sleepers notice the waterproof backing feels warmer or slightly crinkly.

Is this a set or a single protector?

It is one protector per pack, not a set of two.
