One of the major differences between hotel slippers and regular ones is in the comfort level of the wearer. Hotel room slippers are usually made of materials that will guarantee the guest will get pampered. Usually made with soft cotton, plush terry cloth, or even luxurious satin, these slippers provide a cozy feeling that regular slippers probably do not have. While regular slippers can be comfortable, they may not provide the same soft and cushioned experience that you find in hotels.
