The Wonder Sheet Pillow is a unique style of pillowcase uses the same fabric as the Wonder Sheet fitted sheet and the same colour, a creamy/beige.
It has charmeuse satin on the top side against your head and 50/50 blend poly/cotton sheeting on the underside. It was designed with the poly/cotton fabric on the underside to stop if from moving around while you enjoy the benefits of having the satin against your head.
If you have an injured or saw neck, the process of rolling your head over can be difficult and often painful. Its more comfortable to slide your head on satin than normal sheeting as there is less friction.
