Will it fit a 14-inch mattress?

Yes. The protector is listed with a 14-inch deep pocket, so it is made for mattresses up to about 14 inches thick. Thinner mattresses will have extra fabric to tuck.

Is it really waterproof?

Layla lists it as waterproof, with a polyester face and a protective backing. Wash it on a gentle cycle and tumble dry low to keep the backing intact.

What size is Twin XL?

Twin XL measures 35 by 80 inches, five inches longer than a standard Twin. It fits dorm beds and adjustable bases.

It is the only new price listed, $64.00 at Layla Sleep as of November 7, 2026. Without other stores pricing it, there is no lower benchmark to judge against.

Can I machine wash it?
