What material are the hotel bed sheets and quilt covers? 

It depends on how many stars the hotel is, whether it is high-end or not. Like very high-end star-rated hotels, they all use silk bedding. Business hotels are generally made of pure cotton, but this kind of pure cotton is more compact and delicate if it is 300T or 400T.
