Uratex foam cover pls?? What exact material or where to buy?? 🥺

Hi. I am someone na nahihirapan matulog if wala ang testure ng uratex foam cover. Eh I like travelling, and madalas ending walang ganung texture. I want to make it handy at magdadala ako ng cover or pillow case with the exact same texture anywhere I go. Can someone suggest saan makakabili ng same na same na ganung texture as the uratex foam cover??? Or anong exact material yung ganon?? Badly needed. Mahirap matulog ng wala yun. Weird but it’s true. 🥺
